WoWo Sim eSIM Data Plans for Guam

There are no unlimited data eSIM plans offered by WoWo Sim for Guam.
WoWo Sim provides fixed data plans instead, such as a 20GB 30‑day plan priced at $80.00 USD and a 10GB 30‑day plan priced at $42.00 USD. These plans cover Guam and can be more cost‑effective for most travelers unless the user requires extremely high data consumption.

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.
