Tata Docomo — not able to send sms from my sim

I can't send sms from tatadocomo sim while i can sms from my idea sim which is there in the same android.. It's been like this for very long period. I have deleted all my inbox and cleared cache, and tried dialling#33*1234# by seeing one of the customer review.. But nothing works

I was not able to check even my bank account balance due to this issue
