eSIM2Me does not offer any Belgium eSIM plans that include a phone number or SMS capability. Available plans for Belgium are data‑only, providing high‑speed internet access without inbound or outbound voice or text services. Travelers who need to make calls or send messages can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in Belgium before purchasing, as some destinations may block or restrict certain apps.
