Seamless operation and excellent support as it was my first time using an eSIM. Much better than purchasing a physical sim as once you move from one country to another you need to physically move a small amount of currency to your account to ensure the physical sim works. eSIM work perfectly.

I’ve received amazing support from this service. It was super difficult as I was travelling in both Egypt and Turkey but the support from Travelkon assisted me and I’m now very happily connected.

Seemlessly changed from country to country as we traveled through Europe. The only city I had patchy internet was Paris. Everywhere else the service was great!
