No Service or No Bars Showing on Your Nesa eSIM: A Step-by-Step Troubleshooting Guide
If your device is showing No Service, No Bars, or simply can’t connect to your Nesa eSIM plan, follow these steps to troubleshoot the issue. We recommend going through them in order; each step rules out a different potential cause.
1. Remove and Reinstall the eSIM Profile
Why This Helps
Sometimes, the original eSIM profile can become corrupted or fail to install properly, causing connection issues.
How to Do It
Delete your existing Nesa eSIM profile:
iOS: Go to Settings → Cellular → Select your Nesa eSIM → Remove Cellular Plan.
Android: Go to Settings → Network & Internet (or Connections) → SIMs → Select the Nesa eSIM → Delete/Remove.
Restart your device to clear any cached data after removing the profile.
Re-install the eSIM using your Nesa Mobile activation QR code or manual activation steps.
Enter the APN details again if they aren’t automatically populated.
Restart the device once more and check if you have service bars.
2. Confirm Your Device Is Unlocked
Why This Helps
If your device is carrier-locked (even partially), it may reject any foreign or non-default eSIM profiles.
How to Do It
Verify with your original carrier that the phone is fully carrier-unlocked.
If you have a physical SIM from another carrier, test it in your phone:
If the phone doesn’t accept the other carrier’s SIM or fails to connect, the phone is likely still locked.
If it works without issue, then your phone should be unlocked.
3. Perform a Full Network Settings Reset
Why This Helps
Resetting your network settings erases stored carrier profiles, Wi-Fi networks, and possible corrupted data, giving you a clean slate to re-apply APN settings.
How to Do It
iOS: Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
Android: Go to Settings → System → Advanced → Reset Options → Reset Wi-Fi, mobile & Bluetooth (path varies by device).
After the reset:
Re-enter your APN settings for Nesa eSIM, if needed.
Enable Data Roaming for the Nesa eSIM (on iOS, under Settings → Cellular → Nesa eSIM).
Restart your device and see if the connection is restored.
4. Disable or Remove Any VPN/Firewall Apps Temporarily
Why This Helps
VPNs or firewall apps can interfere with how your device connects to mobile data networks. If they block or reroute traffic, you may see “No Service” or experience dropped connections.
How to Do It
Turn off or uninstall any VPN or firewall app.
Restart your device and attempt to use the Nesa eSIM again, without a VPN.
If service resumes, you may need to adjust your VPN settings or whitelist the Nesa eSIM network.
5. Check Manual Network Selection and Band Compatibility
Why This Helps
Not all devices support every carrier frequency. Manual network selection can help verify if a supported carrier is available.
How to Do It
Switch to Manual Network Selection:
iOS: Settings → Cellular → Network Selection → Disable Automatic.
Android: Settings → Network & Internet → Mobile Network → Advanced → Select network manually.
Wait for your device to display available networks, such as Telkomsel or Indosat in Indonesia.
Select each supported network one by one to see if you can establish a connection.
If your phone can see the network but can’t connect, verify that your phone’s frequency bands are compatible with those carriers. Some regional models may not support all local frequencies.
6. Confirm Account Status and Plan Activation on Our End
Why This Helps
Sometimes, issues occur on the back end—like a stuck provisioning process or incorrect ICCID/EID details.
How to Do It
Contact Nesa Mobile Support (or let us know in the live chat) to confirm:
Your account is fully active.
The eSIM profile is registered correctly.
The ICCID and EID (or IMEI) match your current device.
Ask Support to refresh or reprovision your plan from our system.
7. Escalate to Our Tier-2 Support
If you’ve gone through all the steps above and still see No Service, please:
Gather any screenshots (e.g., APN Settings, Network Selection, error messages) and device details (make/model, software version).
Send them to our Support Team. We can escalate your case to our Tier-2 or network specialists for an in-depth review.
We may need to work directly with our carrier partners to resolve deeper network issues.
Additional Tips
Keep Your Device Updated: Ensure your phone’s operating system is running the latest version.
Recheck Data Roaming: Even if you’re using the eSIM domestically (in supported countries), some devices require data roaming settings to be turned on.
Use Stable Internet for Setup: When adding or refreshing an eSIM, make sure you have a reliable Wi-Fi connection or an active cellular data connection on another SIM card.
