Flysimio eSIM Data Plans for Guam

Flysimio does not provide an unlimited data eSIM plan for Guam. The available options are fixed data plans, such as the Guam 20GB 30Days plan and the Guam 10GB 30Days plan, which offer 20GB or 10GB of data for 30 days of validity. For travelers who need more data, Flysimio also offers global plans that include Guam, such as the Global (120+ areas) 20GB 30Days and Global (120+ areas) 10GB 30Days plans, which provide the same data allowances but cover additional countries. Choosing a fixed data plan can be more cost‑effective unless a user requires truly unlimited data usage.

Flysimio does not provide a Guam eSIM plan that includes a phone number or SMS capability. Travelers who need a local phone number for calls or texts will find that only data‑only plans are available from this provider. However, popular Voice‑over‑IP applications such as WhatsApp, Telegram, and iMessage can typically be used over the data connection to make calls and send messages. Because some destinations restrict or block certain VoIP services, travelers should verify that the apps they rely on are accessible in Guam before purchasing a Flysimio data plan.

Flysimio presents seven single‑country plans that cover Guam exclusively, and a further seven multi‑country plans that include Guam as part of a broader regional package. Most of these plans are fixed‑data offerings, providing a set amount of data for the entire validity period, while one product is a daily data‑cap plan, limiting usage on a day‑by‑day basis. Across the catalog the price ranges from roughly $6.23 to $166.25, and the data caps span from 1 GB up to 20 GB.
