I will be contacting my cell phone provider as those are the rules when you want get the codes that the Ofcom people say you must have to use your mobile number you have now, somewhere else. My son had to change his phone, he found whenever he traveled for his company he couldn’t get any connection half the time so he had no choice. The cell company was nice enough to wave the early termination fees since he really had problems. And they also gave him his port authorization code so he could take the same number with him due to all the clients he takes care of having his contact number.
