Zwitchy eSIM Data Plans for Guam

Zwitchy does not provide a truly unlimited data eSIM for Guam. The plans listed as “Guam · Unlimited” grant 1 GB of high‑speed data per day and, once that daily limit is reached, the speed is reduced to 1000 kbps. Consequently, the high‑speed data allotment is limited, and the speeds throttle after the cap.

Travelers looking for larger data allowances can choose from Zwitchy’s fixed‑data plans, such as the 10 GB plan valid for 30 days at $89.50 USD or the 5 GB plan for 30 days at $47.00 USD. These plans provide the stated data amount without throttling, making them a more cost‑effective choice for high‑data‑use travelers.

Zwitchy does not offer eSIM plans that include a phone number or SMS capability for Guam. Their Guam eSIM products are data‑only, providing high‑speed internet without local voice or text services.

Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict certain messaging services, so it is advisable to confirm that the apps you rely on are accessible in Guam before purchasing a Zwitchy eSIM.

Zwitchy offers 11 single‑country eSIM plans for Guam, with no multi‑country options available. The plans span a price range from $11.00 to $223.50 and cover data amounts between 1 GB and 10 GB, valid for 3 to 30 days. Of these, seven plans feature a daily data cap while four provide a fixed data cap. Tethering is permitted on most plans, though some may experience reduced speeds at 1000 kbps.
