How does an eSIM work?
An eSIM is a digital SIM built into your phone that activates mobile data without a physical card. After purchase, you install the Guam eSIM in one tap from your order email. Once you arrive in Guam, your phone connects to local networks automatically—no SIM swaps or roaming fees.
How do I install Guam eSIM on iPhone?
Open your order email on your iPhone and tap the install button: the eSIM installs in one tap, then follow the prompts. Once installed, select the eSIM as your data line. You’ll need to enable Data Roaming on the eSIM line (not your primary SIM) to connect in Guam.

Can I install my Guam eSIM before travel?
Yes! Install anytime before your trip—it won't activate until you arrive in Guam and connect to a local network. You have 180 days from purchase to activate.
Do I need to turn on Data Roaming for Guam eSIM?
Yes, enable Data Roaming on the eSIM line (not your primary SIM). This allows the eSIM to connect to local networks in Guam. You won't be charged roaming fees—it connects as a local plan with no extra charges from your home carrier.
Does Guam eSIM support hotspot/tethering?

Will WhatsApp work with a data-only eSIM?
Yes! WhatsApp and iMessage stay linked to your home number. The Guam eSIM is data-only, so your existing messaging apps work perfectly—you keep all your chats and contacts.
Can I make calls with a data-only eSIM?
This eSIM doesn't include a phone number for regular calls/SMS. However, you can make calls using WhatsApp, FaceTime, Skype, or other internet-based apps over your data connection.

Is Guam eSIM better than buying a local SIM?
Yes—no airport queues, passport checks, or language barriers. Install your Guam eSIM before you travel, land at Guam’s top attractions like Marine Corps Museum or explore UnderWater World, and connect instantly. Local SIMs require finding a store, dealing with paperwork, and physical swapping.
