CHECK BEFORE YOU BUY

Is your device eSIM-ready?

You need an eSIM-capable, network-unlocked device. Availability can vary by model, country of purchase and carrier, so check the device itself—not only the model name.

Quick device check

  1. Open your SIM settings. On iPhone, go to Settings → Cellular/Mobile Data. On Android, go to Settings → Network & Internet or Connections.
  2. Look for “Add eSIM”, “Add Cellular Plan” or “SIM manager”. If one appears, your device likely supports eSIM.
  3. Confirm it is unlocked. Ask your carrier if you are unsure. A carrier-locked phone may reject a travel eSIM.
  4. Check software requirements. The Terrtel iPhone app currently requires iOS 13.0 or later; the iPad app requires iPadOS 13.0 or later.
Important: Support can differ within the same model family. Always confirm in your device settings before buying.
