TooSim eSIM Data Plans for Guam

TooSim does not provide an unlimited data eSIM option for Guam. The plans it offers for the territory are fixed‑data packages, such as the 20GB plan valid for 30 days, the 10GB plan valid for 30 days, and smaller packages like 5GB and 3GB, each with a 30‑day validity. These plans include tethering and are priced at $117.99, $69.99, $42.99, and $25.99 respectively. For the same coverage area, there are also 2GB plans valid for 15 days.

Choosing a fixed‑data plan can be more cost‑effective for most travelers, especially those who do not exceed the allocated data. Unlimited plans are only warranted for very heavy data users, but in this case TooSim’s current offerings require a pre‑determined data allowance rather than unlimited usage.

TooSim does not provide Guam eSIM plans that include a local phone number or SMS capability. All available Guam eSIMs from TooSim are data‑only. Travelers can still use data‑based VoIP applications such as WhatsApp, Telegram, and iMessage for voice and messaging, but the plan itself does not offer traditional phone number services.

TooSim lists six single‑country data plans for Guam. The plans span a price range from $13.99 to $117.99, with data caps between 1 GB and 20 GB and validity periods of 7 to 30 days, and some plans allow tethering.
