Bordersim does not provide a Guam eSIM that includes a phone number or SMS capability. The offers are limited to data‑only plans, so users will not receive inbound or outbound voice or text services.
Travelers who need messaging or calling can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may restrict access to certain apps or VoIP services, so it is advisable to confirm that the services you rely on are available in Guam before purchasing an eSIM from Bordersim.
