Ofcom has greenlighted new regulations forcing mobile operators to allow customers to move their mobile number to another network in one working day.
The regulations will require operators to provide customers with that all important PAC number either immediately over the phone or within a maximum of two hours by text message.
At present, customers often have to wait for the PAC number to arrive by letter, which can take several days.
"Ensuring consumers can switch between communications providers by removing unnecessary barriers is one of Ofcom's priorities for 2010/11. Being able to switch quickly and easily between mobile providers is an important part of healthy and effective competition," Ed Richards, Ofcom chief executive, said.
While it is great news for customers, many will be left frustrated that the regulation will only come into force on 11 April 2011.
It currently takes around two days to change network if users want to keep their number, claimed Ofcom.
It's not all bad then as think back to 1999, when the agonising wait could take as long as 25 days because of the fax-based systems used to process requests. Yes, fax machines, remember those?
