It’s more interruptive, but reminders should work this way :) In the world there is nearly 5 billions mobile phone users.

Because of that SMS becomes as effective communication medium as e-mail.

If you have some kind of Saa S or different app, you can use SMS for two-factor authentication or recovering lost password.It’s crucial to have correct number in database for such occasion.So your user can provide his number himself in some registration process. But how would you build expression for all countries over the world? Even if it’s 0.01$, let 100,000 registrations have invalid mobile number for the first time, and you’ll send 100,000 * 0.01$ = 1,000$ in outer space.In all those cases you want to ensure that number is valid. Validation problem is not trivial as numbers are very country specific. If it even would be possible, it would be an overkill to maintain it. Country codes can have variable length (from 1 to 3 digits) and so can numbers, valid area codes are country specific and there’re some additional rules which number must follow in chosen countries. So, next thought would be to send an SMS to number provided by user. Such code would assure that number is 100% correct. As user won’t receive message, he’ll probably catch typo but you get the point.

I’ll show you what I’ve learned about mobile number, how to store it in database or what you can expect from user.

If you’re simply running business, notification about special offer sent via text message would be more direct than e-mail.
