Cell Phone Number Capture

Is there a way to capture someones cell phone number when they visit a certain link from their cell phone other than an opt in form?

Say for instance they clicked on a link from their cell phone to enter to win a free smoothie or whatever...they are redirected to the webpage. We get the cell number and they get the coupon. Of course the tiny letters at the bottom of the page would state something along the lines of them agreeing to opt in to our SMS program haha.

Possible or no??? :baby09:

I don't think you can get the phone number so easily from a simple script or any other server side method
see some ads on website for free music download etc.. they always request the phone number for sms subscription.
So if they can't grab it, i think we can't take it too.

I think that's impossible..

When someone visits your website, its through the internet by their telecom company. They are not using their phone line to access it, they are using the data line of the same provider.

So its practically impossible to hijack their phone number. Only option you have is, put a request to enter their number before they can see the content or whatever you have.
