Is your eSIM not working while traveling abroad?

This is one of the most common issues travelers face after landing in a new country. You may see signal but have no internet, or your eSIM might not connect at all.

The good news: most eSIM problems can be fixed in a few minutes.

This guide explains the most common causes and how to fix your eSIM not working abroad step by step.

Common eSIM Problems While Traveling

  • eSIM connected but no internet
  • no signal after landing
  • slow mobile data
  • eSIM not activating

1. Turn On Data Roaming

This is the most common issue.

  • go to mobile settings
  • select your eSIM
  • enable data roaming

Without roaming enabled, your eSIM will not work abroad.

2. Check If eSIM Is Selected for Mobile Data

  • open mobile network settings
  • make sure your eSIM is set as primary data line

Sometimes your phone still uses your main SIM.

3. Toggle Airplane Mode

  • turn airplane mode on
  • wait 10 seconds
  • turn it off

This forces your phone to reconnect to the network.

4. Restart Your Phone

A simple restart can fix network issues instantly.

5. Manual Network Selection

  • go to network settings
  • disable automatic selection
  • choose a local carrier manually

This helps when your phone connects to a weak network.

6. Check APN Settings

Most eSIMs configure automatically, but sometimes APN must be set manually.

If needed, check your provider instructions.

7. Make Sure Your Device Supports eSIM

Not all devices support eSIM.
