Address:

Kurukshetra, Haryana, 136118

I requested to port my mobile no.[protected] from vodafone / idea to airtel. For that i am requesting by sending sms to 1900 but the sms get failed every time ant not going. For that i contact vodafone customer care. He is not giving any satisfactory answer and just say that there is problem in internet. All other sms is going and there is not problem of internet for that.in my opinion vodafone is blocking the porting request. Please help me, and order to port my mobile no.[protected] from vodafone to airtel.
