Receiving sms message Without typing your phone number (5)

Receiving sms message Without typing your phone number

Hello everyone!

My friend has a recently established sms subscription company. He is struggling with a problem right now and I want to explain it to get some help.

Generally, when it comes to PIN submits, it works like this (as far as I know); user puts his phone number, receives sms message with PIN, then puts the PIN into the field and is subscribed.
The problem is, how is it possible to receive sms message after clicking a button on a website Without Typing your phone number? How does it know your phone number? It goes like this; a user lands on the page, clicks ‚Register’ and automatically receives sms with PIN.
Any specialist can help me?

Interesting fact is, testing websites with such software has shown, that it's possible only on phones with facebook application installed. But that's not confirmed yet .

In WAP billing models, the mobile carrier passes the MSISDN (phone number) in the headers of the webpage to provide a more seamless purchasing experience for the user. This will generally only work on carrier 3g/4g traffic.

Yeah, that's exactly what I was looking for. So this works for all carriers? They are sending it automatically? Or I need a kind of agreement with the carrier?

You need to make some kind of agreement with any carrier that you actually plan to work with, otherwise they won't pay you for the subscriptions you generate. I never did the setup personally, but from what I know, there are companies who handle these billing relationships for some fee or you can go straight to the carrier, which costs more initially and doesn't make sense for small operations.

I am sure that you need agreement with the carrier to get paid for subscriptions. But I was asking about specific deal with the carrier to send users' mobile numbers in http headers. IF they don't do it automatically of course which would be pretty bad when it comes to our privacy.
