Why buy a Guam travel eSIM from Olysim
Buy online before you fly
Order a prepaid Guam data plan online and get the QR code by email in seconds. Your mobile data is ready before you land.
Keep your home number
The eSIM runs as a second line on your phone. Your home SIM stays active for calls, texts and security codes, while Olysim carries the data.
No international roaming charges
Pay one fixed price for the data you use in Guam instead of your home network's daily roaming rate. No bill waiting for you at the end of the trip.
What is an eSIM and how does a travel eSIM work?
No physical SIM to swap
An eSIM is a digital SIM built into your phone. You never open the SIM tray or risk losing your home SIM card - you just add a travel data plan and turn it on when you arrive.
QR code sent by email
Your eSIM QR code arrives by email within seconds of paying. Scan it once in your phone settings to install the plan. Do this on Wi-Fi before you travel.
