Sindhu — airtel sim not connecting to network in uae

Hi
My airtel sim is not working in sharjah and i'm unable to connect to the network. This number is related to bank accounts so i couldn't access anything because of this issue.. I tried manually connect to the network (Du) but no luck.. Can you pls help me out with this issue as soon as possible..

It would be so helpful if you resolved it for me to go further and my mobile number is[protected] and email ([protected]@gmail.com)

Thanks & regards,
