aloSIM does not provide Belize eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for Belize. Travelers can use VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for calling and messaging, but some destinations may block or restrict specific apps or VoIP services, so it is advisable to verify that the services required are accessible in Belize before purchasing a plan.
