Ubigi eSIM Data Plans for Guam

Ubigi does not provide an unlimited data eSIM plan for Guam. The available plans list fixed data allowances, the largest of which is 200 GB for 360 days at $390.00 USD. Other options include 100 GB for 360 days ($290.00 USD), 60 GB per month for 30 days ($140.00 USD) with a reduced speed of 2000 kbps, 50 GB for 180 days ($188.00 USD), and 25 GB for 90 days ($128.00 USD). These plans are available on Ubigi’s 5G network and cover Guam along with over 200 other countries. Choosing a fixed‑data plan can be more cost‑effective unless a traveler requires a true unlimited data allowance.

Ubigi does not provide an eSIM for Guam that includes a phone number or SMS capability. The provider only offers data‑only eSIM plans for Guam. Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but it is advisable to confirm that the necessary apps work in Guam because some destinations may block or restrict specific services.

Ubigi offers three single‑country plans and sixteen multi‑country plans for Guam. The plans are priced between nine and three‑hundred‑ninety dollars and provide data caps ranging from five hundred megabytes to two hundred gigabytes.
