No surprise fees or roaming chargesAn eSIM is an embedded SIM card, and you probably already have an eSIM-compatible device. When you install an eSIM for a country or region, it lets your device connect to local networks in that area. This means your device will have data without needing Wi-Fi or paying roaming charges.
With white-sand beaches and incredible diving sites, you’ll love every minute of your Guam vacation.
Before you leave on your trip, consider downloading a Guam eSIM (digital SIM card) so your phone has affordable prepaid data anywhere you travel in Guam.
A Guam eSIM is great for pulling up maps, driving directions, messaging, email, and more, especially since Wi-Fi isn’t available everywhere.
Your data requirements in Guam largely depend on your travel plans and personal usage. If you plan on enjoying the tropical outdoors and exploring the pristine beaches, you can’t rely on Wi-Fi availability.
The best thing about a Guam eSIM is that it comes with flexible data plans, so you can start with a smaller package and top up as needed.
We also have a travel data calculator to help you estimate how much data you’ll need for your trip.
Nope! With a Guam eSIM, you won’t pay any roaming charges because it connects you directly to a local network.
Just make sure you’ve turned off Data Roaming on your primary SIM (and confirmed you aren’t enrolled in a carrier travel plan) to prevent your home carrier from adding roaming charges to your next bill.
Most newer phones, tablets, and computers are already eSIM-compatible, so use our eSIM device checker to make sure you have a device that can accept an eSIM.
