nextSIM eSIM Data Plans for Guam

nextSIM does not provide a genuinely unlimited data eSIM for Guam. The plans that use the word “Unlimited” actually give a capped amount of high‑speed data each day—1GB or 2GB per day—and once that limit is reached, the connection throttles to 512kbps or 2000kbps. After the data cap is consumed, any further usage continues at the reduced speed.

Travelers who need a larger data allowance can choose from fixed‑data plans that are not throttled, such as the 20GB plan valid for 30 days priced at $100.93 USD or the 10GB plan for 30 days priced at $56.31 USD. These plans provide predictable data capacity without the speed reductions that apply to the “Unlimited” options.

nextSIM does not provide a Guam eSIM that includes a phone number or SMS capability. The provider offers only data‑only eSIMs for Guam. Travelers can still use voice and messaging apps that rely on data, such as WhatsApp, Telegram, and iMessage, to communicate.

NextSIM provides 18 single‑country plans and 9 multi‑country plans that include Guam. The single‑country entries are normally fixed‑data caps, while the multi‑country portfolio contains a mix of daily‑cap and fixed‑data‑cap options. Across the two categories the price range spans about $7.12 to $329.69 and the data caps vary from 1 GB up to 20 GB, giving travelers several choices depending on how they wish to use their data during their stay.
