FAQ

Common questions about Guam.

Will the eSIM work as soon as I land in Guam?

Activation kicks in the first time you connect to a local network. You may need to enable the Roamo line in Settings → Cellular when you arrive.

Can I keep my home number for calls and texts?

Yes. Roamo is data-only and installs alongside your home SIM. WhatsApp, iMessage, and your phone number all keep working on your primary line.

What speeds will I get?

Full 5G where carriers have rolled it out, 4G LTE elsewhere. We do not throttle — speeds match the local carrier directly.

What happens if I run out of data?

Tap "Top up" in your dashboard. The new data lands on the same eSIM — no re-install needed.

Will my phone work with this eSIM?

Any iPhone XS or newer, recent Pixel, Samsung Galaxy S20+, or modern OnePlus / Xiaomi with eSIM support. We check compatibility automatically at checkout.

How do refunds work?

Full refund within 30 days if you haven’t installed the eSIM on a device. Once installed (even if you never connect to a network), the eSIM is locked to that device and the plan can no longer be refunded.
