nextSIM eSIM Data Plans for Guam

nextSIM does not offer a truly unlimited data eSIM for Guam. All plans that have “Unlimited” in the name provide a capped data allowance of 1GB or 2GB, after which the data speed is reduced to the listed reduced speed (for example, 512 kbps or 2000 kbps). Therefore the high‑speed data is limited rather than unlimited.

For travelers who need more data, nextSIM offers fixed data plans that can be used in Guam. Examples include the 20GB 30Days Standard plan priced at $197.46 USD and the 10GB 30Days Standard plan at $110.16 USD. These plans deliver full‑speed data up to the cap and may be a more cost‑effective choice unless the user is an extremely heavy data consumer.

nextSIM does not provide a Guam eSIM that includes a local phone number or SMS capability. The provider offers only data‑only eSIMs for Guam. Travelers can still use internet‑based messaging and calling apps such as WhatsApp, Telegram, or iMessage over the data connection.

NextSIM lists 22 single country plans and 16 multi country plans that cover Guam. Prices range from $6.97 to $349.32 and data caps vary between 1 GB and 20 GB. The catalogue includes both fixed data plans, which provide a set amount of data for the validity period, and daily data cap plans, which allow purchase of a daily allotment for travelers on short stays.
