The department of telecommunications allocates from time to time new set of MSC codes to operators in certain circles where the operators meet certain qualifying criteria of subscriber base.
DOT has assigned new MSC codes to Bharti Airtel for crossing 1 million new subscriber additions in Odisha, Karnataka and Tamil Nadu circles.
The details of the MSC codes assigned are given below:
| Name of operator | Name of circle | MSC codes allotted |
| Bharti Airtel | Odisha | 73258-73260, 73268-73270, 73278-73280, 73288 |
| Karnataka | 73376-73378, 73380-73386 | |
| Tamil Nadu | 73387-73396 |
The above allocation also includes MSC codes which were previously allotted to other licensees and are hereby withdrawn with immediate effect as the said licences had been quashed by the Supreme court in 2012.

Mr.Madhan and Mr.Sanjit :
In Tamilnadu circle including Chennai :
I am unable to send SMS in the first attempt in the Aircel 3G network using Aircel Tamilnadu SIM in Tamilnadu as well as Chennai Aircel RLH network. Also the incoming SMS gets delayed in the Aircel 3G network.
Outgoing voice calls in Aircel 3G network get disconnected in the middle.
Do you know why?. What about the case in the own 3G network of airtel, BSNL and vodafone?.
