nextSIM eSIM Data Plans for Guam

nextSIM does not provide a plan that offers unlimited high‑speed data while visiting Guam. Plans labeled “Unlimited” in the catalog actually give a set amount of data—typically 1 GB per day in standard plans and 2 GB per day in Plus plans—with a speed reduction after the cap is reached (512 kbps for standard, 2000 kbps for Plus).

If a traveler prefers a fixed data allowance, nextSIM offers several high‑capacity options for Guam, such as a 20GB 30‑day plan at $100.95 USD, a 10GB 30‑day plan at $56.31 USD, or a 5GB 30‑day plan at $30.81 USD. These plans provide the requested data at normal speeds for the full 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 offers 18 single‑country plans and 9 multi‑country plans that include coverage in Guam. The available plans range in price from roughly $7 to $330 and feature data caps between 1 GB and 20 GB. In addition to fixed‑capacity options, which provide a set amount of data to be used within the validity period, there are daily‑cap plans that restrict the amount of data available each day. The most comprehensive products grant up to 20 GB of data for up to 30 days, while the entry‑level offerings start at 1 GB for a single day.
