If your Germany eSIM is not working, showing no service, or you have no internet after arriving in Germany, this is a common issue that can usually be fixed in a few minutes.

Quick Fix

  • Turn Data Roaming ON for your eSIM
  • Select the eSIM for Mobile Data
  • Restart your phone
  • Turn Airplane Mode ON and OFF
  • Try manual network selection
  • Wait 2–5 minutes for network registration

Important: In Germany, network connection can sometimes take a few minutes after arrival due to carrier registration. If your eSIM does not connect immediately, wait 2–5 minutes, restart your phone, or try switching networks manually.

Why Your Germany eSIM Is Not Working

The most common reasons are:

  • data roaming is turned off
  • your primary SIM is still selected for mobile data
  • the eSIM is installed but not activated yet
  • your phone has not connected to a German network automatically
  • temporary weak signal or network congestion
  • incorrect or missing APN settings
  • your phone is not eSIM-compatible or is carrier-locked

How to Fix eSIM Not Working in Germany

1. Turn Data Roaming ON

Travel eSIMs usually require data roaming to be enabled. Go to your eSIM settings and turn Data Roaming ON.

2. Select Your Germany eSIM for Mobile Data

Open your mobile data settings and make sure your Germany eSIM is selected as the line for mobile data.

3. Restart Your Phone

Restarting your device can force it to reconnect to available mobile networks in Germany.

4. Turn Airplane Mode ON and OFF

Enable Airplane Mode for 20–30 seconds, then turn it off. This refreshes your mobile connection and can help your phone register on the network.

5. Try Manual Network Selection

If automatic network selection does not work, choose a German network manually.

Common mobile networks in Germany include Telekom, Vodafone Germany, and O2 Germany.

6. Wait a Few Minutes After Arrival

Sometimes your phone needs a few minutes to register on a local German network, especially immediately after landing or crossing the border.

7. Check Your APN Settings

Some eSIMs require specific APN settings. If your installation email includes APN details, enter them exactly as shown.

8. Check Device Compatibility

If your eSIM does not appear or cannot be activated, check whether your phone supports eSIM and is not locked to another carrier.
