Airtel — Airtel not working in UAE

Address:

Maharashtra

I am an NRI working in Dubai and Visit my native in India once or twice a year. I had subscribed to a Airtel prepaid life time service SIM card and am using it since yesrs. My Mobile phone no is +91-[protected].I tried manually setting up too but the network is not showing. All my bank stuff is connected to that SIM and I need it as soon as possible. Now I am about to complete my continuous stay of 6 months outside india getting this SIM card from Airtel and hence I wish to use it and top up further to keep my SIM active.
I need it as soon as possible to transfer funds for me. Please help me out.
