Trai — changing of mobile network-reg

Address:

Theni, Tamil Nadu

Dear sir/madam,
We, madurai kamaraj university dde. We are using aircel network for our 10 more mobile numbers. Due to network problem, we need to change our numbers into airtel network. So that, we have given port message to aircel 1900. But still we are not receiving any port id.. And moreover we have submitted all the relevant documents to airtel office. We don't receive any response from them. Kindly request you to take the action as early as possible.
