Vodafone India — smsc number

I am not able to send or receive sms. Fix this asap. This is happening since last few days and i have tried to resolve it in many ways but it is not working. I have not received some important sms due to this and it is becoming annoying. So i need this to be fixed. Also i am facing problems in internet connection, it doesn't work many times during the day although i am residing in a city. Fix these sms and internet problems asap.
