Can I set up my eSIM without an internet connection?
Last updated October 14, 2026
No. Setting up the eSIM requires an internet connection — Wi-Fi or your home cellular data both work. After setup, you don't need internet until you arrive in your destination.
Setup downloads the eSIM profile to your phone, and that download needs a connection. Once set up, the eSIM sits dormant — no internet, no data — until your phone connects to a network in your destination.
What counts as a connection for setup
Your home Wi-Fi (easiest).
Café or office Wi-Fi.
Your home SIM's cellular data.
Airport Wi-Fi (works but can be unreliable).
If you've already arrived and can't get online: use your home SIM briefly (a small profile costs pennies even roaming), find Wi-Fi, or borrow a hotspot. The lesson: set up before you fly and skip the airport problem entirely.
