Guam eSIM — FAQ
How do I get an eSIM for Guam?
Pick a Guam data plan below, pay by card or crypto, and we deliver your eSIM instantly. Scan the QR code and you're connected in minutes — no physical SIM, no store visit.
Will my phone work with a Guam eSIM?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3+, and recent Samsung Galaxy S/Z models. Your phone must be carrier-unlocked.
Does the Guam eSIM include 5G?
Yes — our Guam plans connect to 5G where the local network supports it, and fall back to 4G/LTE automatically.
Can I keep my own phone number?
Yes. The eSIM runs as a separate data line, so you keep your main number for calls and texts while using Guam data on the eSIM.
When does my plan start?
Your validity begins when the eSIM first connects to a network in Guam, so you can install it before you travel and it won't start counting down until you arrive.
