Sector watchdog the Telecoms Regulatory Authority of India (TRAI) has issued an amendment to mobile number portability (MNP) regulations, closing a loophole that was preventing the porting of numbers for corporate users. Under the new Telecommunications Mobile Number Portability (Fifth Amendment) Regulations, 2013, up to 50 numbers of a service provider can be ported to another operator in a single request through a letter of authorisation. The time allowed for the porting request to be processed has also been extended to 48 hours for corporate accounts. The measures come into effect in late October. The amendment was drafted in response to complaints that corporate customers were having their porting requests rejected on the grounds of ‘contractual obligation’, in the absence of permission or authorisation from the company or corporation.
