Travelsim Asia eSIM Data Plans for Guam

Travelsim Asia does not offer an unlimited data eSIM for Guam. The provider’s Guam plans are fixed data allowances, with examples including a 20GB plan valid for 30 days at $40.99 USD and a 10GB plan valid for 30 days at $25.00 USD. Choosing a fixed data plan can be more cost‑effective unless a traveller is an extremely heavy data user.

Travelsim Asia does not provide any Guam eSIM plans that include a phone number or allow SMS. All available Guam eSIM plans from this provider are data‑only and do not support voice or text messages. Travelers who need communication while in Guam can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, though some destinations may restrict certain services, so it is advisable to confirm that the apps you rely on are accessible in Guam before purchasing a plan.

Travelsim Asia offers two multi‑country data plans for Guam, with no single‑country plans available at this time. The plans provide between 10 GB and 20 GB of data for a 30‑day validity period, priced from $25.00 to $40.99, and allow tethering on the applicable plans.
