eSIMania eSIM Data Plans for Guam

eSIMania does not provide an unlimited data eSIM for Guam. Instead, the provider offers fixed‑data plans that can be suitable for most travelers. For example, there is a 20GB plan valid for 30 days at a price of $99.94 USD and a 10GB plan valid for 30 days at $56.74 USD. These fixed‑data options give a clear set of allowances that can be more cost‑effective for most users unless very heavy data consumption is required.

eSIMania does not provide a Guam eSIM that includes a local phone number or SMS capability. The provider offers only data‑only eSIM plans for Guam.

Travelers who require voice or messaging can instead use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to these apps, so it is advisable to confirm that the services you rely on are accessible in Guam before purchasing.

eSIMania offers 6 single‑country plans and 3 multi‑country plans for Guam, adding up to 9 distinct data offers. The plans range in price from $7.77 to $268.50, with data caps spanning 1 GB to 20 GB and validity periods between 7 to 30 days.
