What is an eSIM?

An eSIM (embedded SIM) is a digital SIM card built directly into your phone's hardware. Instead of inserting a physical card, you download a carrier profile by scanning a QR code — the whole process takes under 5 minutes.

For European travelers, this means buying one regional plan that automatically connects to the best network in each country you visit. No more hunting for phone shops, no more losing tiny SIM cards, no more connectivity gaps between destinations.

With Dual SIM, you keep your home number active while using a travel data plan — the best of both worlds for connected travelers.
