[Resolved]  Vodafone India — cant make any outgoing calls

I arrived yesterday from singapore and since then i’m not able to make any outgoing calls. It just shows ‘call failed’ every single time i try placing a call. However my internet and incoming calls are working perfectly alright. I looked into my data balance available and it’s validity is upto 4th december, so that is ruled out. No issues with the handset as well as it worked alright before i left. Please look into the issue. Thank you.
