Ubigi eSIM Data Plans for Guam

No, Ubigi does not provide an unlimited data eSIM for Guam. All available Ubigi plans for Guam have defined data caps. For travelers who want a large amount of data, Ubigi offers plans such as a 60 GB/month plan priced at $190.00 USD and a 50 GB plan valid for 180 days priced at $188.00 USD. These fixed data options can be more cost effective than paying for usage as a heavy data consumer, though they still come with a limit. The plans use 3G and 4G networks to deliver service across Guam.

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 a total of 14 data plans that cover Guam: two single‑country plans and twelve multi‑country plans that include Guam among their destinations. The price range varies from about $9.00 for the smallest 500 MB plan to roughly $210.00 for the largest 60 GB plan, with validity periods spanning from 7 to 365 days. In addition to the fixed data‑cap options, there are two daily data‑cap plans where a daily limit is applied to the overall data allowance.
