eSIM Phone Installation Guide by Device Type

Follow these simple instructions to install and set up your eSIM

📶 WiFi Connection Required

For the smoothest installation experience, please connect to a stable WiFi network before installing your eSIM. Sometimes the installation happens quietly in the background - that's perfectly normal! Just check your Mobile Services or SIM manager afterwards to confirm your eSIM was successfully added.

Important Notes Before Installation:

Installation limits: Some eSIMs can only be downloaded and installed once, while others can be reinstalled multiple times (usually up to 3 times max). We strongly recommend not deleting your eSIM as it may not be able to be reinstalled. This is especially so for single use eSIM issued by local eSIM providers and those with single use disclaimers.
Device binding: Each eSIM installation can only be installed on a single device. Once installed, it's tied to that device.
Device requirements: Your phone must be carrier-unlocked and eSIM-compatible.
Data roaming is mandatory: You MUST enable data roaming for the eSIM to work, even in the destination country.
Prevent conflicts: Disable other SIMs/eSIMs when using your travel eSIM.
APN configuration: iOS devices auto-configure APN (except IIJ Docomo Japan eSIM). Android users may need to manually set APN unless already configured - please recheck to be sure.
