I need a web service (Include sending SMS to all over the world & Free with user login and admin Control Panel. Also to include (Add User + Add Coupon or Password To Active The SMS Sender + Limit The SMS Sending For Each Passwor)).
After a user enters text message and a phone number, he should see banner and SMS should be sent after he clicks on it.
I need advice related to the choice of a GSM modem; there are varieties of them on the market. Which should be the most appropriate for this task?
Also, there are many banner providers available. Visitors won't be interested in exploring the advertisers' site so I need a CPC (cost per click) model oriented banner provider. Please suggest one.
