nextSIM eSIM Data Plans for Guam

nextSIM does not provide a truly unlimited data eSIM for Guam. The plans that carry the label “Unlimited” in their names, such as eSIM Guam Unlimited 1Days Standard and eSIM Guam Unlimited Plus 1Days Standard, actually include a fixed data allowance of 1 GB or 2 GB, after which the speed is throttled to 512 kbps or 2000 kbps respectively.

Travelers who need a larger, uncapped data supply can choose from fixed‑data options. For example, the eSIM Guam 20GB 30Days Standard plan provides 20 GB of high‑speed data for 30 days at $97.63 USD, while the eSIM Guam 10GB 30Days Standard plan offers 10 GB for 30 days at $54.46 USD. These plans are available as alternatives for those who prefer a generous data allowance without the speed restrictions that come with the “Unlimited” named plans.

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 supplies data plans for travelers to Guam with a mix of single‑country and multi‑country options. According to the latest catalogue, there are 21 single‑country plans available that focus solely on Guam, and 16 multi‑country plans that include Guam alongside other destinations. The plans vary in structure: some offer a fixed data cap for the entire validity period, while others provide a daily data cap that is credited each day of the plan’s life. Across both categories, prices range from $6.89 to $345.31, and data caps span from 1 GB to 20 GB, giving customers flexibility depending on usage needs and trip length.
