ZenSim eSIM Data Plans for Guam

ZenSim does not provide a truly unlimited data eSIM for Guam. The only plan that carries the word “Unlimited” in its name gives a cap of 3 GB per day over 5 days, which means high‑speed data is limited. Travelers who need more data can choose one of ZenSim’s fixed data plans, such as the 10 GB plans that are valid for 15 or 30 days or the 5 GB plans available for 5, 15 or 30 days. Fixed‑data options tend to be more cost‑effective for those who anticipate using a larger volume of data.

ZenSim does not provide a Guam eSIM that comes with a local phone number or the ability to send or receive SMS messages. The provider offers only data‑only plans for Guam. Travelers who need to communicate while in Guam can use VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection and do not require a traditional phone number or SMS capability.

ZenSim offers 12 single‑country data plans for Guam. All plans cost between $23 and $192, provide data caps ranging from 1 GB to 10 GB, and last 5 to 30 days. The catalogue includes one daily‑data‑cap option, while the remaining 11 plans have fixed data amounts. Tethering is allowed on these plans.
