WonderConnect eSIM Data Plans for Guam

There is no unlimited data eSIM for Guam offered by WonderConnect. All of WonderConnect’s Guam‑specific plans have a fixed data cap of either 10GB or 20GB, each valid for 30 days. For example, a 20GB plan costs $79.99, while a 10GB plan is $44.99.
Fixed data plans can be more economical for most travelers, unless the user needs a very high volume of data. The available plans give clear limits and a set validity, so users can budget their data usage accordingly.

WonderConnect does not provide a Guam eSIM plan that includes a phone number or SMS capability. The only Guam eSIM offered by WonderConnect is data‑only. Travelers who need voice and messaging can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection, but they should verify that these services are accessible in Guam before purchasing, as some destinations may block or restrict specific apps.

WonderConnect provides 5 single‑country data plans and 5 multi‑country plans that include Guam. The single‑country plans give travelers a fixed amount of data ranging from 1 GB to 20 GB, with validity periods of 7 to 30 days, at prices between approximately $9.50 and $150.00. The multi‑country plans offer the same fixed data ranges and validity periods while allowing coverage across multiple destinations, with prices covering the same $9.50 to $150.00 range. Tethering is permitted on selected plans.
