GIGAGO does not offer any Poland eSIM that includes a phone number or SMS capability. All plans available for Poland from this provider are data‑only, with no telephony services included.
Travelers who need voice or messaging can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so it is advisable to verify that the services you rely on are accessible in Poland before purchasing a plan.
