[Resolved]  Idea Cellular — my idea prepaid sim is not working in germany

I'm having a idea prepaid sim since many years. Last three it was worked well in usa. As per the idea customer care representative, it needs to be maintained sufficient balance (Min above rs 500) and regular recharges min rs35. Now i have moved to germany recently and my idea sim stopped connecting to any local network through i've around rs 800 balance in account. Again i have the called the customer care and as per them, i need to manually select the network. I tried to do so many times but no use at all.

Please provide me the feasible solution as soon as possible.
