Ofcom has set a deadline of April 2011 for mobile network operators to speed up the process for their customers to port their numbers to competitors. Customers will be able to change suppliers within 24 hours. Believe it or not as a Service Provider I like this idea because it is good for our customers. It means that we either do a good job of servicing customers or they leave (subject to contract of course J ).
Companies offering good service will prevail. Grauniad article here.
