Activate and start using

Your eSIM will activate automatically when you connect to a supported local network at your destination. First-time activation typically takes a few minutes.

Activation Steps:

  1. Open your phone's Settings
  2. Go to Cellular or Mobile Network settings
  3. Locate the installed eSIM in the SIM card list
  4. Turn on Cellular Data (or Mobile Data) for the eSIM and set it as the primary data line
  5. Enable Data Roaming
  6. Wait 2–5 minutes for the network to connect automatically
  7. Test the connection by opening a browser or app to confirm internet access

Network Optimization Tips:

  1. Set the APN if needed (usually configured automatically)
  2. Turn off unnecessary background data sync for apps
  3. Set data usage alerts and limits
💡 Usage Tips: We recommend checking your data usage regularly to avoid overages. After returning home, you can turn off eSIM data to save battery — the eSIM profile will remain stored on your device.
