eSIM for Guam

In Guam, your eSIM runs on GTA Wireless. It is the network locals rely on, so you get solid coverage in the places you are actually likely to be.

A short trip with light use — maps, messages, a bit of social media — is well covered by a smaller plan. Our 1GB for 7 days at $3.49 is a solid starting point if you are only in Guam for a few days.

For a longer stay, or if you stream music and share photos daily, step up to 3GB for 30 days at $9.88. It gives you enough headroom that you are not watching your data balance the whole trip.

If you would rather not think about a data cap at all, the Guam Data eSIM also comes in an Unlimited option. Full speed up to 1GB a day, then a reduced 1 Mbps for the rest of that day — plenty for maps, messaging and browsing even after the cap. It starts at $3.49 for a single day, or $24.40 for a longer trip.

After you buy, you get a QR code by email. On an iPhone, open Settings, then Cellular, then Add eSIM, and scan the code. On Android, open Settings, then Network, then SIMs, and add an eSIM the same way. Do this before you leave, while you still have wifi — then just switch on data roaming for the new line once you land in Guam.

Home network roaming in Guam can rack up several dollars a day fast, and airport SIM counters mean lines, paperwork and a physical card to keep track of. Install this eSIM before you fly, land, switch it on, and you are connected within a minute — no counters, no plastic, no surprise bill.
