Porting requests were submitted for 4.57 million connections in the month of April 2019, according to the data released by the Indian telecom regulator TRAI. This is down 13.4% from 5.28 million porting requests reported in March 2019.
For April, the maximum number of requests in Zone-I (North and West India) were received from Maharashtra at 0.46 million, followed by Gujarat at 0.37 million, and UP-East at 0.28 million. On the flip side, the least number of requests were received from Jammu & Kashmir, which has one of the lowest user bases among all states in the country, at only 10,000 requests. 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 Andhra Pradesh, with 0.34 million porting requests, followed by Tamil Nadu and Karnataka at 0.32 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.
