GulfData does not provide an eSIM for Guam that includes a phone number or SMS capability. The provider’s offerings for Guam are limited to data-only plans, so users will not receive inbound or outbound voice or text services with the eSIM.
Travelers who need to place calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, access to these apps can sometimes be restricted or blocked in Guam, so it is advisable to confirm that the particular services required are available before purchasing a data-only plan.
