Ubigi does not provide a Belgium eSIM plan that includes a local phone number or the ability to send or receive SMS messages. Travelers who purchase a Ubigi eSIM for Belgium will receive a data‑only plan; the provider does not offer inbound or outbound voice or SMS capabilities in that country.
If a traveler needs to communicate while in Belgium, popular VoIP applications such as WhatsApp, Telegram, or iMessage can typically be used over the data connection. However, some destinations may block or restrict specific VoIP services, so users should confirm that the applications they rely on remain accessible in Belgium before purchasing an eSIM plan.
