Vodafone — Not able to send SMS from my Mobile Phone

Hi,
I am not able to send any messages, to any of the existing contacts as well as the unsaved numbers.I have tried the following things to resolve the issue but it is still not resolved

1.Restarting my Phone(Moto G5S Plus)
2.Changing the slot of the SIM
3.Clearing the cache of Contacts App
4.Force Stop the contact App
5.Changing the SMSC Number (I am a U.P. West Circle User )

Please resolve this issue ASAP as I am not able to login in my Payment Apps due to this .

Thanks and Regards
Amit Kumar
