The Best SMS Gateways for Sending Receiving Messages

Aggregators
Aggregators operate by using multiple agreements with the many different mobile carriers to exchange a two-way traffic connection for SMS messages. These messages go in and out of the operator's Short Message Service Center (SMS-C), also called the 'local termination model.' Unlike the SS7, aggregators deliver messages in an operator's SMS-C, but not the subscriber's handset.
SS7
The SS7 gateway provider uses its connectivity to send SMS messages giving the provider the opportunity to see the SMS messages path during routing. All that means is the message can be delivered to a recipient without the SMS-C of other operators.
SMS Gateway Providers
There are a number of SMS gateway providers out there. Some may be more effective then others. Of the many providers are ICQ, Windows Live Messenger and Yahoo Messenger. There are also a number of websites hat you can go to that provide SMS gateways such as clickatell.com, mblox.com and sms2email.com.
