Btw, I've noticed that you've added NAC to your list of regions. What is it short of? I googled but nothing is coming up.
I have contacted our backend team and they will correct these regions to official region codes. At the moment, I can't say, what NAC is. The same question was for GCC at support. We try to fix these region codes as fast as possible.
UPDATE:
Regarding the mobile phone providers, we have added again many providers. Now, there are about 440 providers from about 148 countries online!
