Check your phone and your selected plan before installing a travel eSIM. Installation adds the profile to your phone; the plan's rules determine when its validity begins.
1. Confirm the exact iPhone model
Apple lists iPhone XS, XS Max, XR and later as the starting point for eSIM support, but regional exceptions apply. Check Apple's current setup guidance for the country variant you own rather than relying only on the model name.
2. Check carrier lock
Open Settings, General, then About. An unlocked iPhone shows No SIM Restrictions beside Carrier Lock. If it is locked, contact the carrier before buying a plan from another provider.
3. Install using the supplied QR code
Connect to Wi-Fi or a hotspot. Follow your order's instructions and scan the QR code, then complete the on-screen prompts. On iOS 17.4 or later, Apple also supports pressing and holding a supported QR code in the default email app or browser, then choosing Add eSIM. Manual entry is another option when the provider supplies those details.
4. Review both SIM lines
Label the travel line clearly and choose it for mobile data when appropriate. Review data switching and roaming settings for each line. Your home carrier's call, text and roaming charges are separate from the travel plan.
5. Check activation instructions
Read the selected plan's validity trigger before installing early. Apply its stated roaming and network settings. If setup fails, keep the error message and contact support; do not delete the profile unless advised, because reinstallation rules can differ.
