Zwitchy does not offer a Malaysia eSIM that includes a phone number or SMS capability. Travelers can only purchase data‑only eSIMs from Zwitchy for use in Malaysia.
If a user requires voice or messaging, VoIP applications such as WhatsApp, Telegram, and iMessage can typically be used over the data connection. However, some destinations may block or restrict access to these apps, so travelers should verify that the apps they rely on are accessible in Malaysia before purchasing a data‑only plan.
