This site provide phone number to receive sms, for verification and activating purpose.
The feature they said on the main page looks promise, but when I fail to create a Google account with their phone number I try to contact to them by submit a support ticket (although they have Skype id but they won't reply when I try to contact by this way), it's took a long time to receive reply from them. Then I request them to give my money back, the one who supporting me with the Chinese name "Wu" don't get my point and he don't reply anymore. I pay $5 from my PayPal and don't get anything from them, there's a 7-day money back guarantee as they said but they don't want to give my money back.
