eSIMania eSIM Data Plans for Guam

eSIMania does not offer an unlimited data eSIM plan for Guam.
Instead, eSIMania provides fixed‑data options that can be suitable for typical travelers. For example, the 20GB plan is available for 30 days at $181.32 USD, the 10GB plan is available for 30 days at $105.06 USD, the 5GB plan is available for 30 days at $61.07 USD, and the 3GB plan is available for 15 days at $40.83 USD. Choosing a fixed data plan can be more cost effective for most users unless a traveler needs an extremely large data allowance.

eSIMania does not provide a Guam eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for Guam, so travelers will need to rely on internet‑based messaging and calling apps such as WhatsApp, Telegram and iMessage to communicate.

eSIMania offers a total of nine data plans for Guam, comprising six single-country plans and three multi‑country plans that include Guam as one of the covered destinations. The plans are normally defined by fixed data amounts ranging from 1 GB to 20 GB and can be purchased for validity periods between 7 and 30 days, with prices spanning from about $15.51 to $268.50. The single‑country options give you data that is used only while you stay in Guam, whereas the multi‑country plans allow the same data allocation to be used across several destinations, providing flexibility for travelers who may visit additional nearby regions.
