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 a Guam eSIM that includes a local phone number or SMS capability. The provider only offers data‑only plans for travelers visiting Guam. Travelers who need voice or text can use VoIP services such as WhatsApp, Telegram or iMessage over the data connection, but no traditional mobile number or SMS service is available from Ubigi in Guam.

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.
