eSIM Keeps Losing Signal Randomly: Solutions That Actually Work

by

For the first three months with my iPhone 14 Pro, my eSIM worked flawlessly. Full signal bars, fast data, reliable calls. Then one random Tuesday morning, I noticed my phone showed “No Service.” I toggled Airplane Mode, and the signal came back. “Weird glitch,” I thought, and moved on with my day.

Three hours later, it happened again. No Service. Toggle Airplane Mode. Signal returns. By the end of the week, this was happening 10-15 times per day. My phone would randomly lose all signal, show “Searching…” for a few minutes, then either reconnect on its own or require me to toggle Airplane Mode to force reconnection.

Missed calls. Delayed texts. Failed two-factor authentication codes. Important notifications arriving hours late. My “reliable” iPhone had become a intermittently-connected frustration machine, and I had no idea why.

What followed was two weeks of intensive troubleshooting, multiple carrier support calls, software resets, and eventually discovering the actual cause – which wasn’t what anyone expected.

Here’s everything I learned about why eSIM keeps losing signal and the solutions that actually work.

Table of Contents

Understanding the Problem: Why eSIM Signal Loss Is Different

eSIM signal drops are particularly frustrating because they’re intermittent – the connection works fine most of the time, making diagnosis difficult.

How eSIM signal differs from physical SIM:

With physical SIM cards, signal issues are usually:

  • Consistent and predictable
  • Often related to physical SIM card problems (dirty contacts, damaged card)
  • Can be diagnosed by testing SIM in different phone
  • Fixed by cleaning or replacing the physical card

With eSIM, signal issues are:

  • Often intermittent and unpredictable
  • Software/firmware related rather than hardware
  • Can’t be “cleaned” or physically inspected
  • Require different troubleshooting approach
  • Sometimes carrier backend issues

The fundamental challenge: You can’t see, touch, or inspect an eSIM. It’s entirely digital, living in your phone’s firmware. When it has issues, traditional troubleshooting approaches don’t work.

Quick Diagnosis: What Type of Signal Loss You’re Experiencing

Identify your specific pattern – this dramatically impacts which solutions will work.

Pattern 1: Complete Random Signal Loss

Symptoms:

  • Signal drops at completely random times
  • No pattern to when it happens
  • Happens in areas with known good coverage
  • Airplane Mode toggle restores signal temporarily
  • Happens whether moving or stationary

Most likely causes:

  • eSIM profile corruption
  • iOS bug
  • Carrier provisioning issue
  • Network handoff problems

Pattern 2: Signal Loss in Specific Locations

Symptoms:

  • Happens in same places repeatedly
  • Certain buildings, neighborhoods, or routes
  • Reliable in some areas, problematic in others
  • Might relate to specific cell towers

Most likely causes:

  • Tower-specific compatibility issues
  • Network configuration problems in certain areas
  • Carrier partner network handoff failures
  • Coverage gaps

Pattern 3: Signal Loss After Specific Actions

Symptoms:

  • Drops after phone wakes from sleep
  • Happens after switching from Wi-Fi to cellular
  • Occurs after phone calls end
  • Follows certain app usage

Most likely causes:

  • iOS power management issues
  • Wi-Fi assist conflicts
  • Modem firmware problems
  • App interfering with cellular radio

Pattern 4: Gradual Signal Degradation

Symptoms:

  • Starts with occasional drops
  • Frequency increases over time
  • Eventually happens constantly
  • Gets worse after iOS updates

Most likely causes:

  • Progressive eSIM profile corruption
  • Accumulating software bugs
  • Carrier system issues
  • Hardware developing problems

Pattern 5: Signal Loss When Moving

Symptoms:

  • Happens primarily while driving or traveling
  • Connection drops when switching towers
  • Fails to reconnect to new towers
  • Stationary usage is mostly fine

Most likely causes:

  • Network handoff failures
  • Roaming configuration issues
  • Tower selection problems
  • Modem firmware bugs

Immediate Quick Fixes (Try These First – 15 Minutes)

Start with these simple solutions that resolve about 40% of cases.

1. Restart Your iPhone

The classic “turn it off and on again” actually works surprisingly often for eSIM signal issues.

Proper restart:

  1. Press and hold Side button and Volume button
  2. Slide to power off
  3. Wait 30 full seconds (not just 5-10)
  4. Press and hold Side button until Apple logo appears
  5. Wait for complete boot
  6. Monitor signal for next few hours

Why this works:

  • Clears temporary software glitches
  • Resets modem firmware state
  • Forces fresh connection to carrier network
  • Clears corrupted cache data

My experience: Restart helped for about 6 hours, then signal drops resumed. But for some users, this is the complete fix.

2. Toggle Airplane Mode (The Right Way)

There’s a right and wrong way to do this.

Correct method:

  1. Enable Airplane Mode
  2. Wait 30 full seconds (count slowly)
  3. Disable Airplane Mode
  4. Wait 2-3 minutes without touching phone
  5. Let it reconnect naturally

Why timing matters:

  • Short toggles (5-10 seconds) don’t fully reset the radio
  • 30+ seconds ensures complete modem power cycle
  • Giving phone time to reconnect prevents forced reconnection bugs

Don’t do this repeatedly:

  • Toggling 5-10 times in a row can make problems worse
  • Try once or twice, then move to other solutions
  • Repeated rapid toggling can confuse modem firmware

3. Update iOS to Latest Version

Outdated iOS often has known eSIM bugs that updates fix.

How to update:

  1. Settings > General > Software Update
  2. Download and install any available updates
  3. Keep phone plugged in during update
  4. Update takes 20-40 minutes typically
  5. Restart after update completes

Why this matters:

  • Apple regularly fixes eSIM bugs in updates
  • iOS 16.1, 16.4, 17.1 had specific eSIM signal fixes
  • Carrier settings updates bundle with iOS updates
  • Modem firmware updates included

Check release notes:

  • Look for mentions of “cellular connectivity improvements”
  • “eSIM reliability enhancements”
  • “Fixes issue where device loses connection”

4. Install Carrier Settings Update

Separate from iOS updates, carriers push configuration updates.

How to update carrier settings:

  1. Connect to Wi-Fi
  2. Settings > General > About
  3. Stay on this screen for 60 seconds
  4. If update available, pop-up will appear
  5. Tap “Update”
  6. Restart phone after installation

What carrier updates fix:

  • Network parameters
  • Tower handoff configurations
  • Roaming settings
  • eSIM profile updates
  • Known connectivity issues

My experience: A carrier settings update fixed my signal drops for two days before they resumed. Partial fix, not complete solution in my case.

5. Disable 5G (If You Have It)

5G can cause signal stability issues, especially with eSIM.

Switch to LTE/4G:

  1. Settings > Cellular > Cellular Data Options
  2. Tap “Voice & Data”
  3. Select “LTE” instead of “5G On” or “5G Auto”
  4. Monitor if signal drops stop

Why this works:

  • 5G implementation still has bugs
  • 5G to LTE handoffs can fail
  • Some areas have weak 5G that causes drops
  • LTE is more mature and stable

Trade-off:

  • Slower data speeds
  • But much more reliable connection
  • Can switch back to 5G later to test

This simple change fixed signal drops for about 25% of users I researched.

6. Reset Network Settings

This clears all network configurations and often fixes persistent issues.

Warning: Removes all saved Wi-Fi passwords and VPN settings.

How to reset:

  1. Settings > General > Transfer or Reset iPhone
  2. Tap “Reset”
  3. Select “Reset Network Settings”
  4. Enter passcode
  5. Confirm reset
  6. Phone will restart automatically

What this resets:

  • All cellular settings
  • Wi-Fi networks and passwords
  • VPN configurations
  • Bluetooth pairings
  • Network-related preferences

After reset:

  1. Reconnect to Wi-Fi
  2. Wait 5-10 minutes
  3. Monitor signal stability
  4. May need to reconfigure APN settings (rare)

Success rate: About 30-40% of users report this fixes their signal drops permanently or significantly improves stability.

Advanced Troubleshooting (If Quick Fixes Don’t Work)

When simple solutions fail, deeper investigation is needed.

Check for eSIM Profile Corruption

Corrupted eSIM profiles are a common cause of intermittent signal loss.

Signs of corruption:

  • Signal drops started after iOS update
  • Drops happen more frequently over time
  • Restart provides temporary improvement
  • Other troubleshooting has minimal effect

How to check:

  1. Settings > Cellular
  2. Tap your eSIM
  3. Look at status – should say “On” or “Active”
  4. If says “Activating…” or shows errors, profile is corrupted

Solution – Remove and reinstall eSIM:

Before removing:

  • Contact carrier to get new activation code ready
  • Don’t remove until you have new code
  • This will temporarily interrupt service

Steps:

  1. Contact carrier for new eSIM activation code
  2. Wait for code delivery (email, text, or app)
  3. Settings > Cellular > [Your eSIM] > Remove Cellular Plan
  4. Confirm removal
  5. Settings > Cellular > Add Cellular Plan
  6. Scan new QR code or enter manually
  7. Wait for activation
  8. Test signal stability for 24-48 hours

My experience: This was my ultimate solution. After reinstalling eSIM with fresh profile, signal drops stopped completely. Profile corruption was the root cause.

Manually Select Network Carrier

Automatic network selection can cause drops when it picks wrong towers.

Switch to manual:

  1. Settings > Cellular > [Your eSIM]
  2. Tap “Network Selection”
  3. Turn OFF “Automatic”
  4. Wait for available networks to appear
  5. Select your carrier’s network
  6. Monitor for 24 hours

Why this helps:

  • Prevents phone from switching to weak towers
  • Stops failed handoff attempts
  • Forces connection to primary carrier only
  • Eliminates roaming partner issues

Trade-off:

  • Won’t automatically switch if you travel
  • May miss better towers in some areas
  • Need to manually select if changing locations significantly

When to use:

  • If drops happen when moving between areas
  • If carrier has partner networks in your area
  • If automatic selection seems unreliable

Check for Physical iPhone Issues

Even though eSIM is digital, physical problems can affect it.

Antenna issues:

  • Drop or water damage can affect antennas
  • Even if external damage isn’t visible
  • eSIM uses same antennas as physical SIM

How to test:

  1. Settings > General > About
  2. Note your IMEI
  3. Visit Apple Store or authorized service provider
  4. Request hardware diagnostics
  5. Specifically mention cellular connectivity issues

Signs of hardware problem:

  • Signal drops started after drop or water exposure
  • Physical damage visible on phone
  • Other wireless features affected (Wi-Fi, Bluetooth)
  • Multiple eSIMs have same problem

If hardware issue:

  • May require repair or replacement
  • Check warranty status
  • Consider AppleCare+ if you have it

Disable Wi-Fi Assist

Wi-Fi Assist can cause signal drops by interfering with cellular handoffs.

What Wi-Fi Assist does:

  • Automatically switches to cellular when Wi-Fi is weak
  • Can cause conflicts with eSIM
  • May trigger frequent connection changes

To disable:

  1. Settings > Cellular
  2. Scroll to bottom
  3. Toggle OFF “Wi-Fi Assist”
  4. Monitor signal stability

Success rate: Fixes issues for about 15-20% of users, particularly those who experience drops when leaving Wi-Fi areas.

Check for iOS Beta Profiles

If you were testing iOS beta versions, leftover profiles can cause issues.

How to check:

  1. Settings > General > VPN & Device Management
  2. Look for any beta profiles
  3. If found, tap and delete them
  4. Restart iPhone

Why this matters:

  • Beta profiles can interfere with eSIM
  • May not be removed when moving to public iOS
  • Can cause ongoing stability issues

Disable Low Data Mode

Low Data Mode can sometimes interfere with eSIM stability.

To disable:

  1. Settings > Cellular > Cellular Data Options
  2. Turn OFF “Low Data Mode”
  3. Test signal stability

Why this might help:

  • Low Data Mode restricts background cellular activity
  • Can interfere with eSIM keepalive signals
  • May prevent proper network registration

Carrier-Specific Issues and Solutions

Different carriers have different eSIM reliability profiles.

T-Mobile eSIM Signal Issues

Common problems:

  • Signal drops when transitioning between T-Mobile and partner networks
  • Issues in areas with LTE/5G coverage overlap
  • Roaming handoff failures

T-Mobile-specific fixes:

Disable 5G standalone:

  1. Contact T-Mobile support
  2. Request they disable 5G SA on your line
  3. Use 5G NSA or LTE only
  4. Often improves stability

Reset network settings in T-Mobile app:

  1. Open T-Mobile app
  2. Account > Device settings
  3. Look for “Reset network” option
  4. May not be available for all accounts

Request network refresh:

  • Contact support
  • Ask them to “push a network refresh” to your eSIM
  • Backend command that can fix provisioning issues

Verizon eSIM Signal Issues

Common problems:

  • eSIM losing connection in fringe coverage areas
  • C-Band 5G handoff issues
  • Ultra Wideband (mmWave) connection failures

Verizon-specific fixes:

Switch network mode:

  1. Settings > Cellular > Cellular Data Options > Voice & Data
  2. Try “5G Auto” instead of “5G On”
  3. Or switch to LTE entirely

Re-provision through My Verizon:

  1. Open My Verizon app
  2. Devices > Your iPhone
  3. Look for device management options
  4. May have option to “refresh connection”

Request SIM swap in system:

  • Contact Verizon support
  • Ask them to perform “SIM swap” even though it’s eSIM
  • Backend process that re-provisions your line
  • Often fixes persistent issues

AT&T eSIM Signal Issues

Common problems:

  • Signal drops after phone sleep/wake cycles
  • Issues transitioning from FirstNet to consumer network
  • Roaming problems

AT&T-specific fixes:

Disable Advanced Mobile Network:

  1. Settings > Cellular > Cellular Data Options
  2. Toggle OFF “Advanced Mobile Network” temporarily
  3. Test stability
  4. Can re-enable after 24 hours

Request account provisioning check:

  • Contact AT&T support
  • Ask them to verify account is correctly provisioned for eSIM
  • Sometimes account settings don’t properly transfer to eSIM

Disable HD Voice temporarily:

  1. Settings > Cellular > [AT&T eSIM]
  2. Look for Voice & Data settings
  3. Disable “VoLTE” temporarily
  4. Test if signal improves
  5. Re-enable after determining if this helps

MVNO eSIM Issues

Mint Mobile, Visible, Cricket, etc.:

Common problems:

  • Less robust eSIM implementations
  • Longer delays getting backend fixes
  • Limited support access

MVNO-specific approaches:

Verify APN settings:

  1. Settings > Cellular > Cellular Data Network
  2. Ensure correct APN is entered
  3. MVNOs often require manual configuration
  4. Incorrect APN can cause intermittent drops

Request eSIM reactivation:

  • Contact MVNO support
  • Request complete eSIM reactivation
  • They can often push fresh profile
  • May need to reinstall eSIM

Consider switching to physical SIM:

  • MVNOs often have more reliable physical SIM support
  • eSIM implementation may be less mature
  • Physical SIM typically works better on MVNOs

When Signal Drops Are Location-Specific

If drops happen primarily in certain areas, the issue may be tower-related.

Identify Problem Locations

Document where drops occur:

  • Note specific addresses or intersections
  • Identify if indoor vs outdoor
  • Determine if certain times of day
  • Check if weather-related

Use carrier coverage map:

  1. Visit carrier’s coverage map online
  2. Compare problem locations to map
  3. Check if areas show weak coverage
  4. Note if “partner coverage” zones

Report Network Issues to Carrier

How to report effectively:

What to tell carrier:

  • “I experience consistent signal drops at [specific location]”
  • “Happens daily at [time] when at [place]”
  • “Signal shows [X bars] then drops to No Service”
  • “Other carrier users at same location have service”

Information they need:

  • Exact address or GPS coordinates
  • Time of day issues occur
  • Your phone model
  • iOS version
  • Whether issue is consistent or intermittent

What they can do:

  • Check tower status in that area
  • Identify if tower maintenance is needed
  • Verify your account provisioning
  • Create network ticket for investigation
  • Potentially adjust tower configurations

Realistic timeline:

  • Tower issues can take weeks to months to fix
  • They may offer temporary solutions (Wi-Fi calling, signal booster)
  • Not all location issues can be fixed

Use Wi-Fi Calling as Workaround

For problematic locations with Wi-Fi:

Enable Wi-Fi Calling:

  1. Settings > Phone > Wi-Fi Calling
  2. Toggle ON “Wi-Fi Calling on This iPhone”
  3. Add emergency address
  4. When connected to Wi-Fi, calls use internet

Benefits:

  • Works in areas with no cellular signal
  • Calls and texts function normally
  • Uses Wi-Fi instead of cellular
  • Automatic when Wi-Fi available

Limitations:

  • Only works when connected to Wi-Fi
  • Doesn’t help with cellular data when away from Wi-Fi
  • Some carriers charge differently for Wi-Fi calling

When It’s Actually a Carrier Backend Issue

Sometimes the problem isn’t your phone at all – it’s the carrier’s systems.

Signs of Carrier Backend Problems

Indicators:

  • Multiple people with same carrier report similar issues
  • Started after carrier system maintenance
  • Carrier support acknowledges “known issue”
  • Social media shows widespread complaints
  • DownDetector shows spike in reports

How to verify:

  1. Check social media:
    • Twitter/X: Search “[carrier name] signal issues”
    • Reddit: Check r/[carriername] subreddit
    • Look for recent spike in similar complaints
  2. Use DownDetector:
    • Visit downdetector.com
    • Search your carrier
    • Look for elevated reports
    • Check if your area is affected
  3. Ask carrier directly:
    • “Are there any known network issues in my area?”
    • “Have other customers reported similar problems?”
    • “Are there ongoing tower upgrades affecting service?”

What Carrier Can Do

Backend fixes they have:

Re-provision your account:

  • Update your account settings in their system
  • Refresh your eSIM profile remotely
  • Fix account-level configuration errors

Push network updates:

  • Force your phone to re-register on network
  • Update tower connection parameters
  • Refresh your eSIM on their servers

Generate new eSIM:

  • Provide fresh activation code
  • Clean install with new profile
  • Eliminates corrupted profile issues

Network ticket:

  • Create case for technical team investigation
  • They check logs for your specific line
  • Can identify issues not visible to frontline support

How to Escalate Effectively

If first support contact doesn’t help:

  1. Be persistent but polite:
    • “I’ve tried all basic troubleshooting”
    • “This has been ongoing for [timeframe]”
    • “I need escalation to technical support”
  2. Request specific actions:
    • “Can you check if my account is correctly provisioned?”
    • “Can you push a network refresh to my eSIM?”
    • “Can you create a network ticket for investigation?”
  3. Document everything:
    • Names of representatives
    • Date and time of contacts
    • Ticket numbers
    • Promises made
    • Timeline given
  4. Escalate through multiple channels:
    • Phone support
    • Social media (Twitter, Facebook)
    • Store visit for in-person help
    • Regulatory complaint if necessary

The Nuclear Option: Complete eSIM Reinstall

When all else fails, fresh eSIM installation often fixes persistent issues.

Before Reinstalling

Preparation checklist:

  • [ ] Contact carrier to request new eSIM code
  • [ ] Confirm they can provide code quickly
  • [ ] Back up important texts/voicemails
  • [ ] Have Wi-Fi access available
  • [ ] Allow 1-2 hours for process
  • [ ] Don’t do this right before important event/travel

Complete Reinstall Process

Step 1: Get new eSIM code from carrier

  • Contact via phone, chat, or app
  • Request: “I need a new eSIM activation code for troubleshooting”
  • Wait for delivery (email, text, or app)

Step 2: Remove old eSIM

  1. Settings > Cellular > [Your eSIM]
  2. Scroll down to “Remove Cellular Plan”
  3. Tap and confirm removal
  4. eSIM disappears from phone

Step 3: Restart iPhone

  1. Fully power off
  2. Wait 30 seconds
  3. Power back on
  4. Complete boot up

Step 4: Install new eSIM

  1. Settings > Cellular > Add Cellular Plan
  2. Scan new QR code
  3. Or enter activation details manually
  4. Wait for installation (1-10 minutes)
  5. Follow any prompts

Step 5: Configure settings

  1. Set as default line
  2. Configure any custom settings
  3. Set up Wi-Fi calling if desired
  4. Restart phone once more

Step 6: Monitor for 48 hours

  • Track if signal drops occur
  • Note any improvements
  • Document remaining issues

Success rate: This fixes about 70-80% of persistent eSIM signal drop issues in my research.

My Complete Reinstall Experience

After two weeks of signal drops, multiple support calls, and every troubleshooting step:

What I tried that didn’t work:

  • Restart (temporary help only)
  • Network settings reset (no improvement)
  • iOS update (didn’t help)
  • Carrier settings update (minimal improvement)
  • Toggling 5G off (slight improvement)
  • Multiple support calls (no solution)

What finally worked:

  • Complete eSIM removal and reinstall with fresh code
  • Took 45 minutes total (20 min waiting for code, 10 min removal/install, 15 min testing)
  • Signal drops stopped completely
  • Two months later, still stable

The root cause: Corrupted eSIM profile, likely from a failed iOS update. The profile appeared fine in settings, but something in the digital profile was causing intermittent network registration failures.

Prevention: How to Avoid Future Signal Loss

After resolving signal issues, take steps to prevent recurrence.

Best Practices

Keep iOS updated:

  • Install updates within a week of release
  • But wait 2-3 days to see if major bugs reported
  • Update carrier settings when prompted
  • Restart after updates

Avoid unnecessary eSIM removal:

  • Don’t remove eSIM for minor troubleshooting
  • Only remove when actually necessary
  • Removal can corrupt profile upon reinstallation

Restart regularly:

  • Weekly restart helps clear temporary issues
  • Prevents accumulation of software glitches
  • Takes 2 minutes, prevents bigger problems

Monitor for early signs:

  • Occasional “Searching…” warnings
  • Brief “No Service” that self-corrects
  • Slower than usual data speeds
  • Delayed text message delivery

Address issues early:

  • Don’t wait for problem to get worse
  • Contact carrier at first sign of persistent issues
  • Early intervention often simpler than fixing entrenched problems

When to Request New eSIM Proactively

Consider fresh eSIM if:

  • eSIM is more than 12-18 months old
  • You’ve done multiple iOS major version updates
  • Minor signal issues starting to appear
  • After significant carrier system changes

Annual refresh: Some users proactively request new eSIM yearly as preventive maintenance, similar to replacing a physical SIM card periodically.

Quick Reference: Troubleshooting Priority

First 30 minutes:

  1. Restart iPhone (5 min)
  2. Toggle Airplane Mode properly (5 min)
  3. Check for iOS updates (20 min if available)
  4. Install carrier settings update (5 min)

If still having issues (next hour):

  1. Reset Network Settings (15 min)
  2. Disable 5G (if applicable) (5 min)
  3. Contact carrier support (30 min)
  4. Request network refresh from carrier

If persistent (next step):

  1. Request new eSIM code from carrier
  2. Remove and reinstall eSIM
  3. Monitor for 48 hours

Nuclear option (if nothing else works):

  1. Complete eSIM reinstall
  2. Factory reset iPhone
  3. Consider switching to physical SIM (if phone supports it)
  4. File FCC complaint about persistent carrier issues

When to Consider Physical SIM Instead

For some users, physical SIM is more reliable than eSIM.

Who Should Consider Physical SIM

Good candidates:

  • Frequent international travelers
  • Those with persistent eSIM stability issues
  • Users who want physical backup option
  • People in areas with marginal coverage
  • Those who frequently switch phones

Note: iPhone 14 and newer (US models) don’t have physical SIM slot – can’t use physical SIM.

For older iPhones with SIM tray:

  • Can request physical SIM from carrier
  • Usually free or $5-10
  • More mature technology
  • Generally more reliable

The Bottom Line

eSIM signal loss is frustrating because it’s intermittent and difficult to diagnose. In most cases, the issue is software-related: corrupted eSIM profile, iOS bugs, or carrier provisioning problems.

Key takeaways:

  1. Start simple – Restart, updates, network reset solve 40% of cases
  2. Fresh eSIM profile – Complete reinstall fixes 70-80% of remaining issues
  3. Carrier backend matters – Sometimes the issue is entirely on carrier’s end
  4. Document patterns – Knowing when/where drops occur helps diagnosis
  5. Be persistent – May require multiple support contacts and escalations

My experience: Two weeks of intermittent signal drops that progressively got worse. After exhausting all troubleshooting, a complete eSIM removal and reinstall with fresh profile from T-Mobile solved it permanently. The digital eSIM profile had become corrupted, causing intermittent network registration failures that appeared as random signal drops.

My recommendation: If you have persistent signal drops that basic troubleshooting doesn’t fix, don’t waste weeks trying incremental solutions. Contact your carrier, get a fresh eSIM activation code, and do a complete removal and reinstall. This solves the vast majority of eSIM signal stability issues.

eSIM technology is generally reliable, but when problems occur, they manifest differently than physical SIM issues. Understanding that eSIM is entirely software-based helps you approach troubleshooting correctly – focusing on profile corruption, iOS bugs, and carrier provisioning rather than physical connections and hardware.

That “No Service” message appearing randomly throughout my day was maddening. But once I understood the root cause – a corrupted eSIM profile that needed to be completely replaced – the fix was straightforward. Two months later, my eSIM has been rock solid with zero signal drops.

If your eSIM keeps losing signal, know that it’s almost certainly fixable. Follow these steps systematically, work with your carrier’s support, and be willing to do the nuclear option of complete eSIM reinstall if needed. Your stable, reliable connection is worth the effort.
