How to fix eSIM not working on Android phones?
Welcome to the Blackview store, which offers phone with projector, thermal camera phone, and slim rugged phone, and more. Hope this guide helps.
eSIM technology has changed the way Android users connect to mobile networks. Unlike traditional SIM cards, an eSIM is embedded directly into the device, allowing users to activate mobile plans digitally without inserting a physical card. However, despite its convenience, many Android users still encounter problems such as activation failure, no signal, network detection issues, or sudden loss of connectivity after updates or carrier changes.

When an eSIM stops working, the problem is not always caused by the device itself. In many cases, the issue comes from incorrect carrier settings, unstable software updates, network compatibility conflicts, or incomplete activation processes. Understanding the root cause before attempting repairs is important because random troubleshooting can sometimes make activation problems even worse. This guide explains the most common reasons behind eSIM failures on Android phones and provides practical step-by-step solutions to restore mobile connectivity quickly and safely.
Common Reasons Why eSIM Stops Working on Android
Before fixing the issue, it is important to identify what may have caused the malfunction. Here are the most common reasons:
- The eSIM profile was not activated correctly
- Android system updates introduced network bugs
- The carrier does not fully support the device model
- Mobile network settings are corrupted
- Airplane mode or network configuration errors interrupted the connection
- The eSIM profile became disabled accidentally
- The device firmware is outdated
- Multiple SIM configurations created conflicts
- Poor network coverage prevents activation
- The carrier temporarily suspended the eSIM service
How to Fix eSIM Not Working on Android Phones
1. Restart the Android Device
A simple restart can refresh temporary network glitches and reload eSIM services.
Steps:
- Press and hold the power button
- Tap “Restart”
- Wait for the phone to reboot completely
- Check whether the mobile signal returns
This basic method often resolves temporary connection failures after software updates or network switching.
2. Check Whether the eSIM Is Enabled
Sometimes the eSIM profile becomes disabled accidentally during system updates or settings changes.
Steps:
- Open Settings
- Go to Network & Internet or Connections
- Tap SIMs or Mobile Network
- Select the eSIM profile
- Ensure the toggle is turned on
If multiple SIMs are active, temporarily disable the unused one to avoid conflicts.
3. Turn Airplane Mode On and Off
Refreshing network communication can force Android to reconnect to the carrier.
Steps:
- Swipe down from the top of the screen
- Enable Airplane Mode
- Wait for 30 seconds
- Disable Airplane Mode
- Allow the network several moments to reconnect
This method is especially useful when the phone shows “No Service” or “Emergency Calls Only.”
4. Update Android Software
Outdated firmware may contain bugs affecting eSIM compatibility and carrier communication.
Steps:
- Open Settings
- Tap Software Update
- Select Download and Install
- Install any available updates
- Restart the device after installation
Manufacturers frequently release fixes for connectivity and eSIM-related issues.
5. Reset Network Settings
Corrupted network configurations are one of the leading causes of eSIM failures.
Steps:
- Open Settings
- Go to System
- Tap Reset Options
- Select Reset Wi-Fi, Mobile & Bluetooth
- Confirm the reset
- Restart the phone
Keep in mind that saved Wi-Fi passwords and Bluetooth pairings may also be removed.
6. Reinstall the eSIM Profile
If activation files are damaged, reinstalling the eSIM can often solve the issue.
Steps:
- Remove the existing eSIM profile from settings
- Contact your carrier for a new QR activation code
- Go to Settings > SIMs > Add eSIM
- Scan the QR code
- Follow the activation instructions carefully
Ensure the phone has a stable Wi-Fi connection during activation.
7. Verify Carrier Compatibility
Not all Android models support every carrier’s eSIM system, especially international variants.
Steps:
- Visit the carrier’s official compatibility page
- Confirm your phone model supports eSIM services
- Check whether your region supports eSIM activation
- Contact carrier support if necessary
Carrier restrictions can sometimes block activation even on technically compatible devices.
8. Contact the Mobile Carrier
If none of the previous methods work, the issue may originate from the carrier’s network system.
Steps:
- Contact customer support
- Request verification of your eSIM activation status
- Ask whether the IMEI is properly registered
- Request a fresh eSIM activation profile if needed
In some cases, carriers may need to manually refresh the line from their side.
eSIM problems on Android phones can appear frustrating, especially when mobile data and calls suddenly stop working without warning. Fortunately, most issues are related to software settings, activation errors, or temporary carrier conflicts rather than permanent hardware damage. By identifying the root cause first, users can avoid unnecessary resets and focus on the most effective solutions.
Following a structured troubleshooting process is the fastest way to restore connectivity. Starting with simple fixes like restarting the device or refreshing network settings often resolves the problem quickly. If the issue persists, reinstalling the eSIM profile or contacting the carrier usually provides a permanent solution. Keeping Android software updated and ensuring carrier compatibility can also help prevent future eSIM failures.
