Tip: Check eSIM support

Check your phone first

Your phone must support eSIM and be unlocked from its carrier. If it is locked, the eSIM may install but not connect. Check your device settings or ask your carrier before buying.

Read the plan details

Look at the countries covered, the data amount, the number of days and when the validity period starts. Some plans start on installation, others on first connection.

Check whether data only, or data with a phone number, is included. Many travel eSIMs are data only.

Install and test

Install the eSIM on Wi-Fi before you travel if the instructions allow it, but do not activate roaming until you arrive if the plan starts on install.

Keep the QR code or install details safe. They usually cannot be reissued once used.

Risks to understand

Locked or incompatible phones may not connect.
Plans that are data only will not receive calls or SMS on your usual number.
Coverage and speeds vary by country and network.
