Ubigi eSIM Data Plans for Guam

Ubigi does not offer an unlimited data eSIM for Guam. Instead, it provides several fixed data plans that give access to high‑speed 3G/4G service on Guam and across 203 other countries. For example, the 60GB/month plan is valid for 30 days and costs $240.00 USD, the 50GB plan is 30 days for $188.00 USD, the 25GB plan is 30 days for $148.00 USD, the 20GB plan is 30 days for $49.00 USD, and the 10GB plan is 30 days for $79.00 USD.

Choosing a fixed data plan can be more cost‑effective for most travelers, unless you are an extremely heavy data user who would prefer unlimited data.

Ubigi does not provide an eSIM for Guam that includes a phone number or SMS capability. The provider offers only data‑only eSIM plans for that territory. Users who need voice or messaging can use internet‑based VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

Ubigi provides 2 single‑country plans and 10 multi‑country plans that include Guam, offering data allowances ranging from 500 MB to 60 GB and prices between $12.00 and $240.00.
