MobiMatter does not offer Belgium eSIM plans that include a phone number or SMS capability. The provider currently supplies only data‑only eSIMs for Belgium.
Travelers who require voice or text services can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. Availability of these apps can vary from one destination to another, so it is advisable to confirm that the services you rely on are accessible in Belgium before purchasing an eSIM.
