Choose a Guam eSIM for your itinerary
Tumon or Tamuning with an airport transfer
Check that Guam is explicitly included in the selected plan rather than assuming a USA offer covers it. Match validity to arrival and departure through your Tumon or Tamuning stay. Save hotel directions and transfer details before boarding the flight.
Hagåtña and a southern island drive
Budget data for navigation away from your Tumon accommodation, including stops around Hagåtña and the southern villages. Check the chosen offer's network information for your driving route. Download a map before leaving Wi-Fi; Guam coverage is not a guarantee of service on every coastal road.
Guam with Japan, Korea or Saipan
Confirm Guam, Japan, South Korea and the Northern Mariana Islands individually as relevant to your flights. Saipan should not be inferred from a Guam entry. Compare the exact regional country or territory list with separate plans, and check whether the first covered connection starts validity before Guam.
Open the current plan's details before buying: check validity, activation timing, coverage, hotspot rules and any fair-use limits. Calls and texts are included only when stated for that plan.
Guam eSIM — frequently asked questions
Everything travelers ask before buying a Guam data plan.
How do I activate my Guam eSIM?
After purchase you'll receive a QR code by email. Scan it from your phone's cellular settings to install the eSIM. Install over a reliable internet connection, then follow the activation instructions supplied with your plan.
Does my phone support eSIM in Guam?
Your phone must support eSIM and be carrier-unlocked. Support varies by exact model and the country where the phone was sold, so check your model and regional variant in our compatibility checker before buying.
Can I keep my regular phone number?
Yes. The eSIM runs as a second line alongside your physical SIM card, so your home number stays on the phone for calls and texts while mobile data comes from the eSIM. Your home carrier may still apply roaming charges to calls and texts; disable data roaming and automatic data switching on the home line.
Do plans for Guam include calls and texts?
Not here yet. These plans are data-only, so keep your home SIM active for calls and texts, or use WhatsApp, FaceTime and other apps over the eSIM's data. We do sell plans that include a phone number for many other destinations.
How much does an eSIM for Guam cost?
Plans start from $5.99 on Wanderly, depending on the selected data allowance and duration. Check the available plans above for the current total price and coverage.
When does my plan start?
Most plans begin when the eSIM first connects to a supported network in Guam or the covered region. Activation rules can vary, so check the instructions for your selected plan before installing or turning it on.
