Before you buy a travel eSIM

Check that your exact phone model supports eSIM and is carrier unlocked. Compare the countries covered, data allowance, validity, activation rules, hotspot restrictions and total price on the current plan page. Coverage and speeds depend on the local network, your device and location; a 5G label does not guarantee 5G everywhere. Read the installation instructions before activating, because the validity start rule can differ between packages.
