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 simple steps to troubleshoot the issue. We recommend going through them in order, starting with the quickest and easiest solutions.
1. Enable Data Roaming
Why This Helps
Even when using your eSIM in supported countries, most devices require data roaming to be enabled for eSIMs to function properly.
How to Do It
iOS: Go to Settings → Cellular → Select your Nesa eSIM → Turn on "Data Roaming"
Android: Go to Settings → Network & Internet (or Connections) → SIMs → Select the Nesa eSIM → Mobile Data → Enable "Data Roaming"
Restart your device and check if service is restored.
2. Check and Update APN Settings
Why This Helps
APN (Access Point Name) settings tell your device how to connect to our network. Incorrect settings are a common cause of connectivity issues.
How to Do It
Find your correct APN settings in:
The Nesa Mobile app under "Plan Details"
The Nesa website dashboard under "Plan Details"
Update your APN settings:
iOS: Go to Settings → Cellular → Select your Nesa eSIM → Cellular Data Network → Update APN fields with the provided information
Android: Go to Settings → Network & Internet → SIMs → Select the Nesa eSIM → Access Point Names → Add New APN → Enter the settings and save
Restart your device and check for connectivity.
3. Try Manual Network Selection
Why This Helps
Sometimes automatic network selection doesn't choose the best available carrier in your location.
How to Do It
iOS: Settings → Cellular → Network Selection → Turn off "Automatic" → Wait for the list to populate → Select a supported network
Android: Settings → Network & Internet → Mobile Network → Automatically select network → Turn off → Select a supported network
Try each available network to see which provides the best connection.
4. Perform a Network Settings Reset
Why This Helps
This clears any corrupted network data without affecting your personal data.
How to Do It
iOS: Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings
Android: Go to Settings → System → Reset options → Reset Wi-Fi, mobile & Bluetooth
After resetting, re-enter your Wi-Fi passwords and check your eSIM connection.
5. Remove and Reinstall the eSIM Profile
Why This Helps
If the above steps don't work, your eSIM profile might be corrupted.
How to Do It
Delete your existing Nesa eSIM profile:
iOS: Settings → Cellular → Select your Nesa eSIM → Remove Cellular Plan
Android: Settings → Network & Internet → SIMs → Select the Nesa eSIM → Delete/Remove
Restart your device
Re-install the eSIM using your Nesa Mobile activation QR code or manual activation steps
Enter the APN details using the information from Step 2
Enable Data Roaming as in Step 1
6. Check Device Compatibility
Why This Helps
Not all devices support the same cellular bands used in different countries.
How to Do It
Confirm your device is carrier-unlocked (contact your original carrier if unsure)
Check that your device supports the frequency bands used in your current location
Test another SIM card if available to verify your device can connect to mobile networks
7. Disable VPN or Firewall Apps
Why This Helps
VPNs and security apps can sometimes interfere with mobile connections.
How to Do It
Temporarily disable any VPN apps
Check for security or firewall apps that might be blocking connections
Restart your device and test the connection
