Getting online in Guam
A travel eSIM is a data plan you install before departure and switch on when you land, so your phone is online in Guam without roaming charges and without hunting for a SIM counter at arrivals. Your home number stays where it is.

Guam travel eSIM questions
Will my phone work with an eSIM?
Two things decide it, and both are on your handset, not on any plan: the phone must be eSIM capable, and it must be carrier unlocked. Most phones sold in the last few years are both; phones bought on a carrier contract often are not until the contract ends. We do not test handsets — your phone's settings screen and your carrier can tell you.
Do I keep my own number?
Yes. A travel eSIM sits alongside the SIM you already use, so calls and messages to your home number keep arriving. You choose which line carries mobile data.
When should I install it?
Before departure, while you still have wi-fi. Installation needs a connection; switching the line on when you land does not.
Why are there no prices on this page?
Because we do not measure them. Plans, data amounts and validity are set by our partner and change week to week. You see them on the partner's own page, where they are current.
