Hi,

Recently i ported my prepaid network from vodafone to airtel. I got message that number will be porting to airtel on 07/08/2018 (Dd/mm/yyyy) but till now i am facing issue to activate my number. Always it is showing as no service. I went to nearest airtel store to check with the status. They are responding like it will activate tomorrow and tomorrow. I went there thrice and i got the same reply from the executive.
