yaySIM eSIM Data Plans for Guam

Travelers who need a larger data allowance can select one of these fixed data plans; the 20GB 30‑day package costs $62.49 USD, while the 20GB 90‑day package is $101.91 USD, and the 10GB 30‑day plan costs $43.94 USD. Choosing a fixed data plan can be more cost‑effective unless a user requires truly unlimited data usage.

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.
