Zwitchy does not provide a phone number or SMS capability for Pakistan. Travelers who choose a Zwitchy eSIM for Pakistan will receive a data‑only plan; no inbound or outbound telephony services are included. They can, however, use VoIP applications such as WhatsApp, Telegram and iMessage over the data connection to make calls and send messages. Because some destinations may block or restrict access to certain apps or VoIP services, travelers should verify that the applications they need are reachable in Pakistan before purchasing a Zwitchy eSIM.
