I have been using it for about 2 years and I am very satisfied. I used it in Greece, Bulgaria, and Romania, and I experienced internet speeds that I haven't seen in Turkey.

I bought the eSIM for a holiday in Tibet. Everything was great; with the integrated VPN I was able to access all the sites that are normally blocked in China (Google, WhatsApp, etc.).
