Nope, no web application has access to this kind of information

Well, there actually might be a way -- but it isn't web application specific, involves some manual work and enquiring with the mobile network operators, and is country-dependant.

Here in South Africa, you can ask the mobile networks to enable MSISDN forwarding, which assuming the user is coming through the correct gateways (this is still murky waters to me), the mobile number of the user will be available to you in the HTTP headers sent through to the page.

Perhaps the mobile networks in Kenya have some similar functionality? It could be worth an ask.

am really thankful because have really researched on that but never got anywhere

Ok, Ok, now you're just getting pedantic :p
This kind of approach needs you to prove your case to the operators in question, and it's not foolproof because of how the mobile gateways operate. And as for roaming users ... ;)

This is true. But, to be even more pedantic, @sach didn't stipulate the difficulty involved :P

But, as you said, it's definitely not foolproof, and definitely not something that can be relied upon absolutely :)

Oh, and @sach, have you chatted to the network operators about how to enable this MSISDN forwarding? Or have you just done research about it on the internet?

@GARBETJIE I look forward to having more pedantic discussions with you :p

@Garbetjie am on tight schedule trying to win the nokia n72 mini series mobile phone competition but planned to pass through there tomorrow ill get back at you @daniel am trying to use the my web application to help developers in kenya get cash out of our local way of money transfer, that uses the phone sms, you need to get to our level for you to understand this. could this be at your place @Garbetjie maybe we could start get on board. help developers get more.
