Mobile Number Portability (MNP) requests jumped nearly 24 per cent in May to 105.70 lakh subscribers, from 85.41 lakh in the preceding month, data released by Telecom Regulatory Authority of India (Trai) showed.
According to Trai, in all, 105.70 lakh subscribers had submitted requests until May to different service providers under MNP, a service that allows people to change operators while retaining the same number.
Of these, 6.32 lakh pertain to Haryana, where MNP was implemented from November 25, 2010. Overall, maximum requests were received from Gujarat (10.53 lakh), Rajasthan (8.25 lakh), Karnataka (7.95 lakh) and Tamil Nadu (7.74 lakh).

According to May visitor location register (VLR) data, the number of active mobile users were only 588.13 million - against the total subscriber base of 840.28 million.
VLR numbers provide details on active customers at any given point of time, excluding switched-off and out-of-coverage area customers.
"The total active VLR number excludes the CDMA VLR figure of BSNL, as the state-owned operator did not provide the VLR figures corresponding to their total CDMA subscriber base of 5.37 million," Trai said.
