Why RoamZivo for Guam
Skip the rental counter
No pocket Wi-Fi or SIM counter to find when you land in Guam, and nothing to return before you fly home. The eSIM is installed before you leave.
Share with your laptop
Hotspot is allowed on the plan selected above, so a second device can use the same data in a cafe or a hotel room.

Guam travel data guide
A Guam eSIM from RoamZivo is a prepaid data plan for Guam that you install before you fly. Plans in Guam run on GTA Wireless and Docomo Pacific, with 5G where the operator offers it. The eSIM is data only, so your own SIM stays in for calls and texts.
There are 11 plans to choose from. Data sizes run from 1 GB to 20 GB, validity from 1 to 30 days, and prices start at $9.99. Unlimited plans are listed too, each with its own fair use line. Hotspot sharing is supported on every plan. Top ups are available on the fixed data plans and go onto the same eSIM.
Your days start the first time the eSIM connects in Guam, not when you buy, so you can install it at home days early. For a week of maps, messaging and social apps, most travellers are fine with 3 to 5 GB. Video calls or streaming need more, or an unlimited plan. Travel data in Guam from RoamZivo arrives as a QR code by email, with a copy kept in your account.
Guam FAQ
Does the eSIM work everywhere in Guam?
It connects wherever GTA Wireless and Docomo Pacific have signal, which is the same network local customers use. The eSIM is data only.
When do my days start?
On the first connection in Guam, not at purchase. The plan selected above (3 GB) runs for 30 days from that moment. You can install the eSIM at home and the clock stays still until you connect.
Do I get a local phone number in Guam?
No. The eSIM is data only. Your own SIM stays in for calls and texts, and WhatsApp keeps working over the eSIM data.
Can I share data with my laptop?
Yes. Hotspot sharing is supported on the plan selected above, so your laptop or tablet can use the eSIM data through your phone.
What happens after 1 GB a day on the Guam unlimited plan?
After 1 GB in a day, the Guam unlimited plan keeps going at up to 5 Mbps instead of full speed. You stay online for browsing, maps and messaging. Full speed returns at the start of the next day.
Is 10 GB enough for two weeks in Guam?
10 GB is enough for two weeks in Guam for nearly any normal use, including daily maps, social media and some video. The 10 GB plan is valid for 30 days. Lighter users can manage on 3 GB for 15 days.
Does a regional plan cover Guam?
No, none of our regional plans covers Guam. You need the Guam plan itself. If you are also visiting other countries, you can keep a second eSIM for those on the same phone and switch between them.
Do I need to scan the QR code in Guam?
No, scan the QR code at home over WiFi before you travel. The plan only starts when the eSIM first connects to a network in Guam, so early installation does not shorten it.
Should data roaming be on for the Guam eSIM?
Yes, data roaming needs to be on for the eSIM line, because a travel eSIM connects as a roaming line. Leave data roaming off on your home SIM to avoid charges from your own carrier.
Can I use my phone as a hotspot in Guam?
Yes, hotspot is allowed on all Guam plans. On unlimited plans the shared data counts toward the 1 GB of full speed each day, so a connected laptop will reach the slower speed sooner.
Can I top up a Guam eSIM?
Top up is offered on some Guam plans and not on others. The plan card says which. When top up is not offered on your plan, you can buy another plan once the first is used up.
How do I top up if I run low?
Open My eSIMs, pick this eSIM and choose a top up. It goes onto the same eSIM, so there is no new QR code to scan.
