Most of the people here need US and Europe phone number.
No, many businesses do not care where you live and which country numbers, you are using. Good example : Gmail verification.
If you can provide us these number with the same price, it will be the best phone verification I have ever seen in this forum. Anyway,Egypt is too damn good too
Yes, I do not see any problem in using Egypt numbers so this must be one of good services with vast numbers, will turn best if it will be available at required times.
