154 million mobile customers worldwide have ported their numbers

The Telecommunications Management Group, a US-based telecomms consultancy, says 154 million mobile phone customers in 48 countries worldwide have kept their mobile telephone number when changing networks. Their new report about mobile number portability (MNP) points out that China and India have yet to introduce MNP - and says that statistically every mobile phone customer in Hong Kong has ported their mobile number at least once.
