MyTravel eSIM does not provide a Poland eSIM plan that includes a phone number or SMS capability; the provider only offers data‑only plans for this destination. Travelers who need phone calls or text messages can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict access to certain VoIP services, so it is advisable for travelers to verify that the apps they rely on are available in Poland before purchasing a plan.
