2-Way SMS

The recent emergence of 2-Way Short Messaging Services (SMS) gives the subscriber the capability to send messages from a mobile device to a database and get information in return. A 2-Way SMS application can act on any message received from a SIM and use it to generate another message as a reply. Within a short span of time, it has emerged as one of the most exciting capabilities that SMS offers today.

There are several advantages in using this feature:

• Mass reach: All users of GSM now have access to SMS messaging and hence can make use of it.
• Mobile owners need not have special WAP-enabled phones and do not need to have data calls enabled on their phones.
• There are no long waiting periods to get connected to an ISP and pay for it. You only pay for the SMS that you send. Receiving an SMS is free of cost, though some service charges may be accrued for the information received.
