Does what it’s supposed to

I needed cellular data in Italy and then Albania and Yesim came through. Had a little trouble connecting with network in Italy but chat support resolved it minutes.

The best

Setup was quick, activation took just a few minutes, and the connection worked well as soon as I arrived. The support team was also super helpful and responsive. Very convenient for travel!

Best ESIM out there

I’ve tried almost every mainstream eSIM provider out there and Yesim is now my go to! The customer service is 10/10. Super helpful always.
