yaySIM eSIM Data Plans for Guam

No, yaySIM does not provide an unlimited data eSIM plan for Guam. Instead, yaySIM offers fixed‑data plans, such as the GU_20_30 plan that gives 20GB for 30 days and the GU_10_30 plan that provides 10GB for 30 days. These examples illustrate the range of options available; other fixed‑data plans may also be appropriate, particularly if cost effectiveness is a priority, unless a user consumes extremely high volumes of data.

There is no yaySIM Guam eSIM plan that provides a local phone number or SMS capability; only data‑only options are offered. Travelers wishing to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but should verify in advance that these services are accessible in Guam before purchasing.

yaySIM lists a total of 12 single‑country data plans that can be used on Guam, and 9 multi‑country plans that include Guam among their coverage areas. The single‑country plans range in price from about $7.94 to $38.50 for data volumes between 500 MB and 5 GB, while the multi‑country plans are priced from roughly $27.00 up to $101.15 and provide data caps between 2 GB and 20 GB. Overall, customers can choose from a mix of fixed data‑amount plans and, for the multi‑country options, bundles that include daily usage limits as well as longer‑term data allocations.
