Ubigi eSIM Data Plans for Guam

Ubigi does not provide an unlimited data eSIM plan for Guam. The available plans are fixed‑data packages that range from 10GB up to 60GB per month. For example, the 60GB/month plan is valid for 30 days and costs $220.00 USD, while a 50GB plan is valid for 180 days at $188.00 USD. Other options include 25GB for 90 days, 20GB/month for 30 days, and 10GB for 30 days. Choosing a fixed data plan can be more cost effective for most travelers, unless a user expects to consume data beyond the highest available 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 two single‑country plans for Guam and ten multi‑country plans. Prices span from roughly $9 to $220, while data caps range between 500 MB and 60 GB over validity periods of 7 to 365 days. Some plans deliver a fixed data amount, whereas others provide a daily data allowance.
