Guam eSIM

Pick a Mobiily data plan for Guam online, pay, and receive a QR code by email within seconds. Scan it once and your device connects to a local network in Guam. Setup takes about two minutes — no physical SIM, nothing to ship.

Mobiily currently has 13 Guam data plans, starting from 3,24 $. Prices are tax-inclusive with no surprise roaming fees.

Guam plans range from 1 GB – 20 GB, valid up to 365 days. For a short trip, maps and messaging usually fit in a few GB; pick a larger plan for longer stays, streaming or hotspot use.

In Guam your Mobiily eSIM connects to local networks via our carrier partner — confirmed operators in this market include GTA Wireless. 5G plans are available.

You can install the eSIM as soon as you receive the QR code. Most plans start their validity from first activation (connecting to a network in Guam), so you can install ahead of time on Wi-Fi and only activate when you arrive.
