eSIM Not Working? Here’s How to Troubleshoot

If your Firsty eSIM isn’t working, don’t worry—most eSIM issues, including eSIM connectivity issues, can be resolved quickly with a few simple troubleshooting steps. Whether you’re experiencing connection problems, activation failures, or network issues, this guide will help you get back online.

Step 1: Check if Your Device Supports eSIM

Not all devices support eSIM technology. If you’re unsure whether your phone is eSIM-compatible, check:

1⃣ Go to Settings > General > About.

2⃣ Look for the Digital SIM section. If you see an IMEI number there, your device supports eSIM.

💡 If your device does not support eSIM, you will not be able to use a Firsty eSIM. In this case, you will need to rely on a physical SIM card for cellular services.

Step 2: Ensure Your Phone is Unlocked

If your phone is carrier-locked, it will not allow you to install an eSIM from another provider.

To check:

1⃣ On iPhone, go to Settings > General > About.
2⃣ Scroll to Carrier Lock. If it says “No SIM restrictions”, your phone is unlocked.
3⃣ If it’s locked, contact your carrier to request an unlock.

💡 Firsty eSIMs only work on unlocked devices.

Step 3: Confirm That Your eSIM is Installed Correctly

To check if your eSIM is installed:

1⃣ Go to Settings > Cellular (or Mobile Data on Android).

2⃣ Under SIMs, check if your Firsty eSIM is listed.

3⃣ If your eSIM is there but not active, tap it and toggle Turn On This Line and check your eSIM settings.

💡 If your eSIM does not appear in the settings, you may need to reinstall it.

Step 4: Check If Mobile Data is Enabled

If your eSIM is installed but not connecting, ensure mobile data is enabled:

1⃣ Go to Settings > Cellular (or Mobile Data on Android).

2⃣ Tap Cellular Data and select your Firsty eSIM.

3⃣ Make sure Data Roaming is turned ON.

💡 If Data Roaming is OFF, your eSIM may not work outside your home country.

Additionally, verify your APN settings to avoid connection issues, as incorrect settings can hinder internet access.

Step 5: Restart Your Phone and Disable Airplane Mode

A quick restart can often fix connection issues.

1⃣ Turn off your phone.
2⃣ Wait 30 seconds.
3⃣ Turn it back on and check if your eSIM connects.

Step 6: Reset Network Settings

If your eSIM is still not working, try resetting your network settings:

  • On iPhone:

    1⃣ Go to Settings > General > Transfer or Reset iPhone.

    2⃣ Tap Reset > Reset Network Settings.

  • On Android:

    1⃣ Go to Settings > System > Reset Options.

    2⃣ Tap Reset Network Settings.

💡 This will reset WiFi, Wi-Fi networks, mobile, and Bluetooth settings, but won’t delete your eSIM.

Step 7: Check If Your eSIM Plan is Active

If your Firsty eSIM was working before but has stopped, check if your plan is still active:

1⃣ Open the Firsty App.

2⃣ Go to the Support Section.

3⃣ Check your remaining data balance and validity period.

💡 If your plan has expired, you will need to buy a new eSIM in the Firsty App.

Additionally, it is important to check with your eSIM provider for detailed plan information and support for any connectivity issues.

Step 8: Reinstall Your Firsty eSIM

If none of the above steps work, reinstall your eSIM:

1⃣ Open the Firsty App.

2⃣ Go to the Support Section.

3⃣ Select Buy a New eSIM and follow the setup instructions.

💡 Unlike other providers, Firsty does not use QR codes. You can install a new eSIM directly from the app.

However, if you are using a provider that requires a QR code for eSIM activation, ensure you store the QR code securely to prevent loss of access.
