Giga.Tel eSIM Data Plans for Guam

Giga.Tel does not provide a true unlimited data eSIM for Guam. The plans that carry the “Unlimited” label actually allow only 1 GB of high‑speed data each day; after that amount the speed is limited to 512 kbps. Travelers who need more data can choose from Giga.Tel’s fixed‑data plans, such as the 34 GB annual plan for $78.49 USD or the 20 GB plan valid for 30 days priced at $143.99 USD. These options deliver larger data allowances without the daily cap and generally offer better value for heavy data users.

Giga.Tel does not provide a Guam eSIM that includes a phone number or SMS capability. Only data‑only eSIM plans are offered. Travelers can still use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection to make calls and send messages without a local phone number.

Giga.Tel offers eight multi‑country data plans for Guam, all sold through its eSIM catalogue. The plans cover a price range from $46.49 to $195.99 and provide data caps between 1 GB and 34 GB, with validity periods spanning from 5 up to 365 days. Half of the options are daily data cap plans, meaning the data allowance refreshes each day, while the other half are fixed data cap plans that allot a set amount of data for the entire validity period. Tethering is permitted on every plan, although some may experience a speed reduction to 512 kbit s.
