Instabridge does not provide a Poland eSIM plan that includes a phone number or SMS capability. Only data‑only plans are offered for Poland.
Travelers who need voice or text services can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict specific apps or VoIP services, so individuals should verify that the applications they rely on remain accessible in Poland before purchasing.
