Surprisingly, it worked for me
After reading a single person's review of saying "out on x numbers, some worked", it was good enough for me so I tried. I needed a Turkish number for a gmail account, I selected one that lasted for 15 mins, verified with no problem and continued on my way. The next day I tried using again a Turkish number but it says they are out of Turkish numbers, and asked me if I wanted something else close to that area, which I declined (So they probably fixed the issue with being given used number). I have a very unexpected and positive experience, even though it looked like a scam, it worked for me. Have fun you guys
