WoWo Sim eSIM Data Plans for Guam

WoWo Sim does not offer an unlimited data eSIM plan for Guam. The provider’s offerings for Guam are fixed data plans, such as 20GB for 30 days priced at $85.00 USD and 10GB for 30 days priced at $45.00 USD. These plans are available for purchase as a single‑purpose travel eSIM. Choosing a fixed data plan can be more cost‑effective for most travelers unless the user requires extremely high data usage that would otherwise exceed the allowance.

WoWo Sim does not offer a Guam eSIM that includes a phone number or SMS capability. The provider’s Guam plans are strictly data‑only.

Travelers who need voice or messaging services can use VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection and provide a practical alternative to traditional phone number and SMS functionality.

WoWo Sim offers five single‑country data plans and eleven multi‑country data plans for Guam. The plans available span a price range of roughly $4.99 to $120.00 and include data caps from 1 GB up to 20 GB, with validity periods between 7 and 90 days. The single‑country options grant data use strictly within Guam, while the multi‑country options allow usage across several destinations while still providing a set data allowance for the entire validity period.
