Vodafone — unable to send text messages

Address:

Hyderabad, Andhra Pradesh

Hello,

I'm using a moto g3 mobile with a vodafone sim and there is a problem with sending text messsages. I'm unable to send text messages and it says "message not sent" and none of the messages are sent.

Earlier it used to work without any problem. I could send the messages to any other number without any problem through this vodafone sim. Now, messages are not being sent from this number [protected], a vodafone sim.

Please look into this asap.

Thanks in advance
