Available plan durations are 1, 3, 5, 7, 14, 15 and 30 days.

You can choose 1GB, 3GB, 5GB, 10GB or 20GB plans, or select an unlimited data plan.

Guam: is an eSIM better than a local SIM?

For most travellers, yes. A local SIM in Guam means finding a shop once you have landed, usually with ID in hand, and it leaves you on a single carrier. An eSimHero eSIM installs before you travel, works the moment you arrive, connects across the networks we carry there, and leaves your usual number active on the same phone.

The eSIM connects to GTA Wireless on a 4G network in Guam. Coverage is limited to Guam, as this is a local destination plan.

How much data you need

Light users can choose 1GB or 3GB for essentials such as maps and messaging. For more regular browsing, social media and photo sharing, 5GB or 10GB may be suitable. A 20GB or unlimited plan gives you more allowance for heavier use. Data-only service is provided, so calls and texts are not included. Top-ups are supported if you need more data during your stay.
