Step 1:

The user needs a specific number to send his messages to SMS gateway. You can use either long code or short code which is provided by your SMS Gateway Provider.

A short code is a 5-6 digit code like 56767. Long code is 10 digit number. It is like mobile number but not the mobile number. It’s called Virtual Mobile Number(VMN).

Step 2:

After receiving SMS from user, SMS Gateway sends the user mobile number and request message details to application server.

Step 3:

Application server generates response for the particular user’s request from server and sends back to SMS Gateway via HTTP API.

Step 4:

SMS gateway forwards the same back to user’s mobile number immediately.

Feature of two way sms:

  • It can be used for customer feedback
  • Used for customer survey
  • Online Voting
  • Most of the time this  SMS services can be used for customer enquiry
