Avelis eSIM does not offer Poland eSIM plans that include a mobile phone number or SMS capability. Travelers purchasing a Poland eSIM from Avelis will receive only a data-only plan. While phone calls and text messages can still be made over the internet using VoIP applications such as WhatsApp, Telegram and iMessage, some destinations may block or restrict access to certain VoIP services, so it is advisable to verify that the messaging or calling apps you rely on are accessible in Poland before purchasing.
