eSIM for Guam

Frequently asked questions

When should I install the eSIM?

Install before your flight while you still have Wi‑Fi. Data validity usually starts when the eSIM first connects to a network at your destination.

Does the eSIM support hotspot?

Many plans support hotspot / tethering. Check the Hotspot label on each plan card before you buy.

Which networks will I use?

Roamio routes you onto local partner networks at the destination. Supported networks are listed on the plan where available.

Can I top up after my data runs out?

If your plan supports top-up, you can add more data from your order page without installing a new eSIM.

Will this work on my phone?

Your device needs eSIM support and must be carrier-unlocked. Use our device checker on the home page or how-it-works guide if you are unsure.
