Airtel — Airtel SIM card stopped working while Roaming in Qatar

Same here, started to have this issue as mentioned three weeks back before this post. Having this number in Qatar for few yers now and they have been charging min till now. I managed to recharge one year data pack as they "removed all but the min charge to 99rs w/o incoming or outgoing sms", which wont help as we need OTP facility. So i recharged one year data pack and have 365 days validity. Then i switched to manual mode for network selection as well. But right now when i tried, its not even picking the signal on two different phones. We just require atleast incoming SMS facility as our number is connected to bank and govt utilities back in India.
