Not Receiving any messages from internet

#1
6 months ago I brought a spice coolpad mi-496 mobile, from the time itself, i didn't receive any confirmation messages like a message from OTP password from internet banking, way2sms , online verification code.

No more problem with my SIM card, if i want OTP code or else i put my SIM card to another mobile and to get the code. I tried to change so many setting but it doesn't work. What to do? I need your help guys.
