I was thinking the other day, that we are used to subscribe to a list by email. This is when visitors enter their email address to an Aweber form in the website. Then they click the submit button, and confirm their subscription via email.
Is there an Aweber-like service in the mobile website industry? Instead of using email, the visitors need to enter their phone number in the form. Then click submit and confirm their subscription by mobile phone. The member of the list will get update/special offer via sms (text message).
To entice the user enter their mobile phone number, we can simply offer them a big discount on specific product, or any other offers.
