ZenSim eSIM Data Plans for Guam

ZenSim does not offer an unlimited data eSIM plan for Guam. Instead, ZenSim sells a selection of fixed‑data options; for example, the Guam 10GB – 10 Days plan costs $111.00 USD, while the Guam 10GB – 30 Days plan is $120.00 USD. Smaller packages such as the Guam 5GB – 10 Days plan are also available for $65.00 USD. For most travelers, a fixed‑data plan can be more cost‑effective unless very high data usage is required.

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 currently offers eight single-coverage data plans for Guam. These plans provide a fixed data allowance ranging from 1GB to 10GB, with validity periods between 10 and 30 days. Pricing for these plans ranges from $23.00 to $120.00. ZenSim does not currently offer multi-country plans that include Guam. Tethering is permitted with some of the available plans.
