Excellent service. Hasn’t missed a beat, even in outside city areas. Highly recommend.

I’m very impressed. I initially bought another eSIM which I have been for the past three years for my overseas trips. I was happy with it and shared it with friends. But this year after using 1.5gb of data on the first day the high speed would drop down to 1mps which is useless. It was stated as an unlimited eSIM. I was in Japan and it was using China’s mobile network! I was very disappointed. But luckily a fellow traveller was using travelkon and showed me that it was truly unlimited with high speeds. I was happy to pay for another eSIM for the convenience and zero hassles. It was almost half the price for what I paid for the previous one.
I will definitely be using travelkon again on my future trips.
