We have to send sms to international customers, the content will have the rating on product OR the service for example 1 for excellent and 10 for poor.
2. The feedback from the customer to be replied to be for the same SMS number which being used to deliver it to them (please note: we will not provide the separate number for the reply instead the feedback to be for the same SMS no which it delivered).
3. Feedback/reply sms from the customer should not be charged to them.
4.  We would like to have detailed reports and the journey of each customer with respect to the feedback /trend analysis for example month 1 poor is his/her feedback and later after few months based on services 5 later the feedback is excellent, we would like to measure this.
