Description

Guam sits where the Pacific meets a unique slice of American island culture — and whether you’re snorkelling the crystal-clear waters off Tumon Bay, exploring the ancient Latte stone pillars near Agana, watching the sunset from Two Lovers Point, surfing the breaks at Ritidian Point on the north coast, or diving the WWII wrecks off Apra Harbour, your Guam eSIM makes sure you stay connected throughout. No local SIM queue at the airport, no surprise roaming charges — just scan before you board and you’re set.

How It Works

Choose Your Plan
Pick from data plans starting at 1GB up to 20GB and Unlimited, with validity from 1 day to 15 days. A beach holiday calls for something light; an extended stay covering multiple activities suits a larger plan.
Scan Your QR Code
Your QR code arrives in your email within minutes of purchase. Add a new eSIM in your phone settings, scan, and you’re done — takes about 60 seconds. Best done at home before you fly.
Arrive and Connect
Your Guam eSIM activates automatically when you first connect to a local network. Nothing to set up on arrival.

Frequently Asked Questions — Guam eSIM

Q: When should I install my Guam eSIM?
A: Any time after purchase — you don’t need to wait until you reach Guam. Installing it at home on a good WiFi connection before your flight is the smoothest approach. Your data only starts when you connect locally in Guam.

Q: When does my validity period start?
A: From the moment you first use data in Guam — not the day you purchased it.

Q: Do I need to remove my current SIM?
A: No — your main SIM stays in. Just set the Guam eSIM as your data line on arrival, and your regular number keeps working for calls and texts as usual.

Q: Is my phone compatible?
A: iPhone XS and later, Samsung Galaxy S20 and later, and Google Pixel 3 and later all support eSIM, among many others. Check your specific device here.

Q: Can I top up or extend my plan?
A: Yes. Purchase another plan at any time and it gets added to your existing eSIM automatically — no new QR code needed.
