nextSIM eSIM Data Plans for Guam

nextSIM does not provide a truly unlimited data eSIM for Guam. All plans labeled “Unlimited” in the catalog actually grant a capped high‑speed allowance, typically 1 GB or 2 GB, after which the connection speed is reduced to 512 kbps or 2000 kbps.

If an unlimited plan is not required, nextSIM offers fixed‑data options that may be more cost‑effective for most travelers. For example, the eSIM Guam 10GB 30Days Standard plan provides 10 GB of high‑speed data for 30 days at $55.09 USD, while the eSIM Guam 20GB 30Days Standard plan offers 20 GB for 30 days at $98.76 USD. These fixed plans give larger data allowances while keeping the data speed consistent throughout the validity period.

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.
