BNESIM does not provide eSIM plans for Guam that include a local phone number or SMS capability. All available Garmin eSIM plans from this provider are data‑only, meaning they offer internet access but not voice or text services tied to a mainland phone number.
Travelers who need to make calls or send messages can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so it is prudent to verify that the services you rely on are accessible in Guam before purchasing a BNESIM data‑only plan.
