Giga.Tel eSIM Data Plans for Guam

Giga.Tel does not provide a true unlimited data eSIM for Guam. The plans advertised as “Unlimited” actually allow 1 GB per day; once that daily limit is reached the speed drops to 512 kbps. These plans are marketed for short stays (5, 7, 10, or 15 days) and use 4G networks across Guam and many other countries.

For travelers who need more data, Giga.Tel offers fixed‑data plans such as Global 26 GB, Global 20 GB for 30 days, or APAC 34 GB for a full year, all delivered on 4G coverage. Choosing a fixed‑data plan can be more cost effective unless a user requires consistently high‑speed data beyond the daily allowance.

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.
