Esimatic eSIM Data Plans for Guam

Esimatic does not provide an unlimited data eSIM plan for Guam. All of the plans it offers to travelers include a data cap. Fixed data plans are available instead, such as the Global‑Standard plan that gives 50GB of high‑speed data for 90 days at $178.49 USD and the Global‑Standard plan that offers 20GB of data for 60 days at $75.49 USD. Guam‑specific plans also exist, for example a 20GB plan valid for 30 days priced at $92.99 USD and a 10GB plan for 30 days at $51.99 USD.

Choosing a fixed data plan can be more cost effective for most users, especially if heavy data usage is not expected. Unlimited plans are not offered, so travelers who anticipate consistently high data consumption may want to compare the costs of larger fixed data packages before deciding.

Esimatic does not offer Guam eSIMs that provide a phone number or SMS capability. The provider’s Guam eSIM catalog consists solely of data‑only plans. Travelers can still make voice calls and send messages by using VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection.

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.
