4.84 million porting requests were reported in August 2019, according to the data released by the TRAI. This is down 18.7% from 5.95 million porting requests reported in July 2019.
For August, the maximum number of requests in Zone-I (North and West India) were received from Maharashtra at 0.56 million, followed by Gujarat at 0.36 million, and UP-East at 0.33 million. But no change in porting requests were received from Jammu & Kashmir, which has one of the lowest user bases among all states in the country. Note that the TRAI does not provide an operator-wise breakdown for these mobile number porting requests.
In Zone-II (South and East India), the maximum number of requests were received from Madhya Pradesh with 0.39 million porting requests, followed by Andhra Pradesh with 0.36 million requests. The North-East circle saw only 10,000 porting requests for the month.
Note that in November 2017, the TRAI reduced the per port transaction charge for each successful Mobile Number Portability from Rs 19 to Rs 4. The TRAI had capped the porting charge at Rs 19 in 2009, and operators were free to charge any amount less than this if they chose to.
