No outgoing calls on roaming in India

[tecorp]

I have a 2g 8GB iphone running firmware 2.0.1 (using Win PWN 2.0.0.4) using IDEA Cellular as my operator. My problem is that i am able to make and receive calls in my home city - Hyderabad but while on roaming i am able to only answer calls and all outgoing calls give me a Call Failed message.

I used my SIM on a Samsung phone and it works fine (making and receiving calls on raoming). I also put an AirTel SIM and it works fine.

Kindly help!!

Thanks for the response.
However, I am using an IDEA SIM and still have the Call Failed message for incoming calls. I am currently in Orissa. I do not know whether its a prob with carrier bundles.

Any help would be appreciated.
