Zwitchy does not provide Belgium eSIM plans that include a phone number or SMS capability; all of their Belgium offerings are data‑only. Travelers who need an active phone number or SMS service will not find a suitable plan with this provider.
If a traveler still wishes to make calls or send messages when visiting Belgium, popular VoIP applications such as WhatsApp, Telegram, or iMessage can generally be used over the data connection. However, some destinations may block or restrict access to certain apps or VoIP services, so it is advisable to confirm that the preferred services are reachable in Belgium before purchasing a data‑only eSIM from Zwitchy.
