SMS Module Documentation

I downloaded the SMS Module ( and installed SmsTarseel.apk on my android phone following instructions from the documentation. After all the process, tried to used it on my phone and I keep getting the error which says “Unexpected error: Contact program vendor. Details are :No value for respcd”.

What I really need to achieve is for patient to get an SMS 2 days before their appointment.

Is there any other way of achieving this? is the SMS Module still maintained
