Installation and activation are different steps
Installation adds an eSIM profile to your phone. Activation is when the plan becomes usable or its validity begins. Some plans activate on installation, others when they first connect to a supported network, and some follow another provider-defined rule.
The plan’s own activation terms are the source to follow; timing is not identical across providers.
Read the plan’s validity rule
Before scanning a QR code, check when the validity period starts and how long it lasts. If a plan starts on installation, setting it up days early could use part of its validity. If it starts on first network connection, you may be able to install before departure and connect on arrival.
Do not assume “install now, activate later” applies to every plan.
Prepare on a reliable connection
When the plan’s rule permits early installation, use stable Wi-Fi and follow the provider’s device-specific steps. Keep your home line available until you have confirmed the travel line is ready. Save the instructions somewhere accessible offline.
Avoid deleting an eSIM profile to troubleshoot unless the provider says it can be reinstalled. Some QR codes are single-use.
At your destination
Select the travel eSIM for mobile data when you are ready to use it. Turn on data roaming for that line only if the plan instructions require it. Keep an eye on which line handles calls and data, and verify service before relying on it for directions.
If it does not connect, check the selected data line, the plan’s coverage and the provider’s troubleshooting steps.
