SimOptions does not offer any eSIM plans for Pakistan that include a phone number or SMS capabilities. The provider only sells data‑only eSIMs for the destination.
Travelers can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection to make calls and send messages. However, some destinations may block or restrict certain VoIP services, so it is advisable to confirm that the apps you rely on are accessible in Pakistan before purchasing a data‑only plan.
