I am having airtel prepaid card number 1450 for last 2 years.And I am regularly using it and a number of my friends and relatives are having this number to contact me. But as I was in abroad for last three months for special training programe, I was not able to use or recharge my airtel number 450. Recently when I returned my home and try to use my phone , I found airtel simcard registration is failed. I have contacted local airtel customer care office, I was told I cannot get new simcard for this airtel number 450. I was also told this number is issued to other region. I need this number because it is my primary no. For the last 2 years. All my contacts are on it and it is infact ,so please help me to issue new simcard with this number.
