When leaving a network you can easily take your number with you. To do this you will need to call O2 on 0871 909 2304 and request your PAC code. Write it down to call later, but first choose your new network. Once you have called O2 the code will be sent to you via a text message within 48 hours normally.
People choose to go with a different network for a number of reason. Most of the time this is because of no reception to where you have moved to or the phone you want isn't avalible on that network. Which network are you looking at joining?
Orange - Vodafone - T-Mobile - Three
Now that the iPhone is avalible on most other networks then a number of people are looking at leaving O2, so you are not alone. Be aware though, stock for the iPhone is very limited. So if this is the reason you are leaving then you might be best to hold on a little bit longer. Sign up to our newsletter and we will inform you when it becomes avalible.
