Motorola Solutions — I am getting error code 96 while sending message.

Address:	600063
Website:	www.motorola.in

My outgoing messages aren't being sent showing error code 96. It is from last march. I have been trying several things. But nothing worked. Rebooted phone and other steps were done. I am totally dissatisfied. Kindly help. My sim works in other mobiles.
My device is moto g3.
Android version is 6.
I had a problem in receiving incoming calls after the update. But after rebooting phone it got rectified. But outgoing message failure issue still persists.
