      The activation process is not complicated, and it was done quickly by following the steps. The payment method is also flexible. I tried credit card and cryptocurrency payment, and both were completed smoothly, and the payment was immediate. When I arrived at the local area, I scanned the code to connect to the Internet, which is very convenient and very suitable for travel.

      I'm giving 4 stars because the installation guide didn't mention that I had to set up the APN manually, and support also didn't immediately suggest it. I had to do some troubleshooting myself. Other than that, so far so good. P.S. I used it in Turkey and the APN is 'isp.'
