I have read this question and I know that I cannot directly access cell phone number in mobile website. However, is there a way I can access it with user's permission?
I am creating a mobile website of a member program. To register, I will need to verify the mobile number by sending a sms. Sending sms cost a lot, especially if the user is from another country. So I am thinking of another way to verify the user's mobile number, and one way I can think of is to get the mobile number from mobile browser with user's permission. Is this possible or do I have other ways to verify user's mobile number without sending a sms?
I am using PHP with laravel for backend but are willing to switch to any other language or framework if necessary.
