I am unable to port my number to other service due to signal problem. If i send my number to 1900 there is no reply, i also tried the aircel number to port chennai :[protected] but this is also of no use. I also tried the link https://ekyc.aircel.com:444/ekyc/genupc. Html but it implies service temporarily not available. I tried all my way to generate the upc code for aircel. I need this number as it is important for office purpose. I am getting frustrated as i am repeatedly trying to port my number from 2nd march 2018. Kindly help me in generating the upc code please. It will be very helpful to me.
