Esimatic eSIM Data Plans for Guam

Esimatic does not provide an unlimited data eSIM for travelers visiting Guam. The available plans feature fixed data allowances. For example, a 50GB plan with a 90‑day validity costs $178.49 USD, and a 20GB plan with a 60‑day validity is priced at $75.49 USD. These options include tethering and use 2G, 3G, or 4G networks. Choosing a fixed data plan can be more cost‑effective unless the user expects very high data usage.

Esimatic does not provide a Guam eSIM that includes a phone number or the ability to send or receive SMS. Their offerings for Guam are limited to data‑only plans, which give travelers access to Wi‑Fi, 4G, or 5G data depending on the selected package.

Without a built‑in phone number or SMS capability, callers must rely on VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and allow communication without a traditional mobile number.

Esimatic offers 23 single‑country plans and 22 multi‑country plans for Guam. Prices run from $7.49 to $325.10, data caps range from 1 GB to 50 GB, and validity can be anywhere from 1 to 90 days. Plans come in two styles: fixed‑data plans give a set amount of data for the entire validity period, while daily‑cap plans limit the amount available each day, giving travelers more granular control over their usage.
