How it works
An eSIM is a digital SIM built into your phone. There is nothing to post and nothing to swap — you add a travel data plan alongside your normal number.
1. Pick your destination
Search by country, region or choose a global plan for multi-stop trips. Compare data and validity at a glance.
2. Pay in your currency
Checkout as a guest with your email address. Prices include taxes and there is no contract or deposit.
3. Scan the QR code
Your QR code arrives by email and appears on your order page after payment. They are the same code, so scan either one while connected to Wi-Fi.
4. Install (Add eSIM)
Follow your phone's prompts and tap “Add eSIM”. Keep the new travel line turned off until you are ready to use it.
5. Activate
At your destination, select ATravelSIM for mobile data and switch on data roaming for the travel eSIM only.
6. Land & Connect
Your eSIM connects to a supported local network after arrival. Keep your usual SIM active for calls and texts if needed.
