nextSIM eSIM Data Plans for Guam

No, nextSIM does not provide a truly unlimited data eSIM for Guam. The plans that carry the “Unlimited” label give a fixed amount of high‑speed data each day, such as 1GB/day for a 7‑day standard plan or 2GB/day for a 5‑day Plus plan. Once the daily allowance is used, the speed drops to the specified reduced rate—512kbps for the standard versions and 2000kbps for the Plus versions. Travelers who need more data can choose from the fixed‑data options, such as the 20GB or 10GB plans that are valid for 30 days.

nextSIM does not offer any Guam eSIM plan that includes a phone number or SMS capability. All plans available from nextSIM for Guam are data‑only. Travelers can still use VoIP applications such as WhatsApp, Telegram or iMessage over the data connection for voice and messaging, but they should verify that those services are accessible in Guam before purchasing, as some destinations may block or restrict certain apps or VoIP services.

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.
