Giga.Tel eSIM Data Plans for Guam

Giga.Tel does not offer a truly unlimited high‑speed data eSIM for Guam. The plans that carry the term “Unlimited” in their names provide 1GB of high‑speed data per day; once that quota is reached the speed is reduced to 512kbps, so the data itself is not unlimited and throttling applies. Travelers who need more unthrottled data can choose from fixed‑data options such as the APAC 34GB yearly plan or the Global 26GB plan, both of which are available on Guam and provide large high‑speed data allowances without daily limits. Choosing a fixed‑data plan can be more cost‑effective for users who expect to consume more than 1GB per day.

Giga.Tel does not provide Guam eSIM plans that include a phone number or SMS capability. All eSIM offerings for Guam from this provider are data‑only.

Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or over the data connection. These services allow calls and text messages without requiring a local phone number or SMS support.

Giga.Tel offers no single‑country plans for Guam, but it has nine multi‑country plans available. The plans include five daily‑data‑cap options and four fixed‑data‑cap options. Prices run from $23.49 to $195.99, and data caps vary between 500 MB and 34 GB, with validity periods ranging from 5 to 365 days.
