On a compatible unlocked iPhone, adding a travel eSIM normally takes only a few minutes. The exact labels can vary slightly by iOS version.
Before you start
Make sure the iPhone supports eSIM, is not carrier-locked for the plan you want to use, and has a stable internet connection for installation. Keep the eSIM QR code or activation details available on another screen if possible.
- Open Settings.
- Go to Cellular or Mobile Service.
- Choose Add eSIM.
- Scan the QR code or use the manual activation details.
- Label the new line so it is easy to identify while travelling.
Choose the eSIM for mobile data
After installation, open the cellular settings and select the travel eSIM for mobile data. If you want to avoid accidental roaming charges on your primary line, verify that Cellular Data Switching is configured the way you expect.
At your destination
Turn on the travel eSIM line, select it for mobile data, and enable data roaming for that eSIM when required by the plan. Give the phone a short moment to register on a supported network. Restarting the phone or toggling airplane mode can help if the network registration is slow.
Keep the eSIM until the trip is finished
Do not delete the profile simply because the phone has not connected immediately. Verify the plan settings and coverage first. Deleting an eSIM can make reinstallation impossible for some profiles.
Frequently asked questions
Can I install the eSIM before I fly?
Yes. Installing before departure is usually convenient. Check the plan rules to confirm when validity starts.
Should data roaming be on for the travel eSIM?
Many travel eSIMs require data roaming on because they connect through partner networks. Follow the instructions for the specific plan.
