Android Phone Won’t Detect eSIM After Update? Here’s How to Fix It

by

I updated my Android phone last week, and suddenly my eSIM stopped working. No service, no data, and my phone acted like the eSIM didn’t even exist. I panicked because I had important calls to make, but after working through the problem systematically, I got everything working again.

Let me walk you through the solutions, starting with the quickest fixes first.

Check the Basics First

Before diving into complicated troubleshooting, these simple checks solve the problem surprisingly often:

Verify airplane mode is off:

  • Swipe down from the top of your screen
  • Make sure the airplane icon isn’t highlighted
  • If it is, tap it to turn airplane mode off
  • Wait 10-15 seconds for your phone to reconnect

Check if mobile data is enabled:

  • Go to Settings
  • Tap “Network & Internet” or “Connections”
  • Select “Mobile Network”
  • Make sure “Mobile data” is turned on
  • Check that data isn’t disabled for your eSIM specifically

Confirm your eSIM profile is still installed:

  • Go to Settings
  • Tap “Network & Internet” or “Connections”
  • Select “SIM cards” or “SIM manager”
  • Look for your eSIM in the list
  • It should show as installed with your carrier name

Make sure the eSIM is enabled:

  • In the SIM settings, find your eSIM
  • Make sure the toggle switch is turned on
  • If it’s off, turn it on and wait a moment
  • Your phone should detect the network

Restart Your Phone

A simple restart clears temporary software glitches that can happen after an update.

Perform a normal restart:

  • Press and hold the power button
  • Tap “Restart” or “Reboot”
  • If you don’t see those options, tap “Power off”
  • Wait 30 seconds, then turn your phone back on
  • Wait 1-2 minutes for it to fully boot up and search for networks

Check if service returns:

  • Look at the top of your screen for signal bars
  • You should see your carrier name or logo
  • If you see “No service” or “Emergency calls only,” continue troubleshooting

Toggle Airplane Mode

This forces your phone to re-register with the network and often fixes detection issues.

Turn airplane mode on and off:

  • Swipe down from the top of your screen
  • Tap the airplane icon to turn it on
  • Wait 10 seconds
  • Tap the airplane icon again to turn it off
  • Watch for signal bars to reappear (this can take 20-30 seconds)

If that doesn’t work, try a longer wait:

  • Turn airplane mode on
  • Wait 2-3 minutes
  • Turn airplane mode off
  • Give your phone time to find the network

Reset Network Settings

Network settings can get scrambled during an update. Resetting them often fixes eSIM detection issues.

Before you reset:

  • Note that this will erase saved Wi-Fi passwords
  • Bluetooth pairings will also be removed
  • Your eSIM profile should stay installed
  • You’ll need to reconnect to Wi-Fi networks afterward

Reset network settings:

  • Go to Settings
  • Tap “System” or “General Management”
  • Select “Reset” or “Reset options”
  • Choose “Reset Wi-Fi, mobile & Bluetooth” or “Reset network settings”
  • Confirm the reset
  • Enter your PIN or password if prompted
  • Wait for the phone to restart

After the reset:

  • Your phone will reboot automatically
  • Wait for it to fully start up
  • Check if your eSIM is now detected
  • Reconnect to your Wi-Fi network

Check for Carrier Settings Updates

Sometimes your carrier needs to push new settings after a system update.

Look for carrier updates:

  • Go to Settings
  • Tap “About phone”
  • Look for “Software update” or “System updates”
  • Check for “Carrier settings update” or similar option
  • If an update is available, install it

Contact your carrier:

  • Call your carrier’s customer support
  • Tell them you updated your Android version and lost eSIM service
  • Ask if they need to push carrier settings to your phone
  • They can often trigger an update remotely

Disable and Re-enable the eSIM

Toggling the eSIM off and on can force your phone to detect it properly.

Turn off the eSIM:

  • Go to Settings
  • Tap “Network & Internet” or “Connections”
  • Select “SIM cards” or “SIM manager”
  • Find your eSIM
  • Toggle it off
  • Wait 30 seconds

Turn the eSIM back on:

  • Toggle the eSIM switch back on
  • Wait 20-30 seconds
  • Your phone should search for the network
  • Look for signal bars to appear

Check APN Settings

The update might have reset or corrupted your Access Point Name (APN) settings.

View current APN settings:

  • Go to Settings
  • Tap “Network & Internet” or “Connections”
  • Select “Mobile network”
  • Choose your eSIM
  • Tap “Access Point Names” or “APN”

Reset APN to default:

  • In the APN screen, tap the three dots in the upper right
  • Select “Reset to default”
  • Confirm the reset
  • Restart your phone
  • Check if service returns

Manually enter APN settings if needed:

  • If resetting doesn’t work, contact your carrier for correct APN settings
  • Tap the “+” icon to add a new APN
  • Enter the settings provided by your carrier
  • Save the APN
  • Select it as the active APN
  • Restart your phone

Clear Cache for SIM-Related Apps

Cached data from before the update can interfere with eSIM detection.

Clear cache for carrier services:

  • Go to Settings
  • Tap “Apps” or “Applications”
  • Tap the three dots and select “Show system apps”
  • Find “SIM App Dialog” or “SIM Toolkit”
  • Tap “Storage”
  • Select “Clear cache”
  • Do NOT select “Clear data” yet

Clear cache for other system apps:

  • Repeat the process for these apps if you find them:
  • “Phone” or “Dialer”
  • “Carrier Services”
  • “Carrier Hub”
  • Any app with your carrier’s name

Restart your phone:

  • After clearing cache, restart
  • Check if the eSIM is now detected

Update Carrier Services App

Google’s Carrier Services app helps manage eSIM connections and might need updating.

Update Carrier Services:

  • Open the Google Play Store
  • Tap the search bar
  • Type “Carrier Services”
  • If an update is available, tap “Update”
  • Wait for the update to install
  • Restart your phone

If no update is available:

  • Try uninstalling updates to Carrier Services
  • Go to Settings > Apps > Carrier Services
  • Tap the three dots and select “Uninstall updates”
  • Restart your phone
  • The app will update automatically to the latest version

Remove and Reinstall the eSIM Profile

If nothing else works, you may need to delete and reinstall your eSIM profile.

Before you remove the eSIM:

  • Make sure you have your eSIM QR code or activation code
  • If you don’t have it, contact your carrier to get a new one
  • Some carriers charge for reissuing eSIM profiles
  • Do NOT proceed without your activation information

Remove the eSIM:

  • Go to Settings
  • Tap “Network & Internet” or “Connections”
  • Select “SIM cards” or “SIM manager”
  • Tap on your eSIM
  • Look for “Remove eSIM” or “Delete eSIM”
  • Confirm the removal

Restart your phone:

  • Turn your phone off and on again
  • This ensures the eSIM is completely removed

Reinstall the eSIM:

  • Go to Settings
  • Tap “Network & Internet” or “Connections”
  • Select “SIM cards” or “Add mobile plan”
  • Tap “Download a SIM instead” or “Add eSIM”
  • Scan your QR code or enter the activation code manually
  • Follow the prompts to activate
  • Wait 5-10 minutes for full activation

Check for Additional System Updates

Sometimes the first update has bugs that get fixed in follow-up patches.

Check for new updates:

  • Go to Settings
  • Tap “About phone”
  • Select “Software update” or “System update”
  • Tap “Check for updates”
  • If an update is available, download and install it
  • These patch updates often fix eSIM issues

Install security patches:

  • Security updates can also fix cellular connectivity issues
  • Look for both major updates and security patches
  • Install anything available

Boot Into Safe Mode

Safe mode helps identify if a third-party app is interfering with your eSIM.

Enter safe mode:

  • Press and hold the power button
  • When the power menu appears, touch and hold “Power off”
  • A prompt will ask if you want to reboot in safe mode
  • Tap “OK”
  • Your phone will restart with “Safe mode” at the bottom

Test your eSIM in safe mode:

  • Check if you have cellular service
  • Look for signal bars
  • Try making a call or using mobile data

Exit safe mode:

  • Simply restart your phone normally
  • If the eSIM works in safe mode but not in normal mode, a third-party app is causing the problem
  • Uninstall recently added apps one by one

Factory Reset (Last Resort)

This is the nuclear option and should only be done if nothing else works.

Before you factory reset:

  • Back up all your data, photos, and files
  • Write down your Wi-Fi passwords
  • Make sure you have your eSIM activation code
  • Sign out of all accounts or remember your passwords
  • This will erase EVERYTHING on your phone

Perform a factory reset:

  • Go to Settings
  • Tap “System” or “General Management”
  • Select “Reset” or “Reset options”
  • Choose “Factory data reset” or “Erase all data”
  • Read the warnings carefully
  • Confirm the reset
  • Enter your PIN or password
  • Wait for the phone to erase and restart (10-20 minutes)

Set up your phone again:

  • Follow the initial setup wizard
  • Reinstall your eSIM using the QR code or activation code
  • Restore your backup
  • Reinstall apps gradually to identify any problematic ones

Check Phone Compatibility

Some older phones lose eSIM support after major Android updates.

Verify eSIM is still supported:

  • Check your phone manufacturer’s website
  • Look for your specific phone model
  • Check if eSIM is supported on the new Android version
  • Some manufacturers drop eSIM support on older devices

Check carrier compatibility:

  • Visit your carrier’s website
  • Look for their list of eSIM-compatible devices
  • Make sure your phone model is still listed
  • Some carriers stop supporting older phone models

Advanced Troubleshooting

These technical steps might help if you’re comfortable with advanced settings.

Check IMEI numbers:

  • Dial *#06# on your phone
  • You should see multiple IMEI numbers
  • One IMEI is for your physical SIM slot
  • One IMEI is for your eSIM
  • If the eSIM IMEI is missing, that’s the problem

Enable VoLTE and Wi-Fi Calling:

  • Go to Settings
  • Tap “Network & Internet” or “Connections”
  • Select “Mobile network”
  • Turn on “VoLTE” or “Enhanced 4G LTE Mode”
  • Turn on “Wi-Fi Calling” if available
  • These features sometimes need to be re-enabled after updates

Check for stuck provisioning:

  • Some phones get stuck trying to provision the eSIM
  • Dial *#*#4636#*#* (this may not work on all phones)
  • If a testing menu appears, look for “Phone information”
  • Check for provisioning status
  • If you see errors, a factory reset may be necessary

Quick Troubleshooting Tips

If you see “SIM not provisioned”:

  • This means your carrier hasn’t fully activated the eSIM
  • Contact your carrier
  • They need to provision the eSIM on their end
  • This usually takes 5-10 minutes

If you see “No service” but the eSIM is listed:

  • Try airplane mode toggle first
  • Reset network settings
  • Check if your account is in good standing with your carrier
  • Unpaid bills can cause service suspension

If the eSIM worked before the update:

  • The update definitely caused the problem
  • Check for follow-up patches from your manufacturer
  • Consider rolling back the update if possible (requires technical knowledge)
  • Most manufacturers release fixes within 1-2 weeks

If you have dual SIM (physical + eSIM):

  • Try removing the physical SIM temporarily
  • Test if the eSIM works alone
  • Some updates cause conflicts between the two SIMs
  • Reinstall the physical SIM after testing

If you’re using a custom ROM:

  • Custom Android ROMs often have eSIM issues
  • You may need to flash a different version
  • Check your ROM’s forum for eSIM fixes
  • Consider switching back to stock ROM

When to Contact Support

Sometimes you need help from the manufacturer or carrier. Contact them if:

  • Your phone is no longer listed as eSIM-compatible after the update
  • The eSIM IMEI is missing when you dial *#06#
  • Factory reset didn’t fix the problem
  • Your carrier confirms the eSIM is active on their end but your phone doesn’t detect it
  • You get persistent error messages about SIM provisioning

I went through this exact problem with my Samsung Galaxy after the Android 14 update. The eSIM just disappeared completely. What finally fixed it for me was resetting network settings first, then removing and reinstalling the eSIM profile. My carrier (T-Mobile) had to send me a new QR code, which was annoying but free. The whole process took about 30 minutes. The key thing I learned is to always save your eSIM activation code somewhere safe before doing major updates – I didn’t have mine backed up and had to spend 45 minutes on the phone with customer service to get a new one.
