FAQ on O2 phone deals
What are the benefits of O2?
When it comes to benefits of a O2 phone deal, the best known part comes in the form of O2 Priority. This is a scheme which offers the likes of competition entries, free tickets, coffees and other benefits.
Those that sign up with O2 also get access to events that O2 is sponsoring and most importantly, O2 covers 98% of the UK when it comes to coverage meaning you should never be worrying about signal.
Can I keep my number when I switch to O2?
You sure can, if you switch over to an O2 mobile deal and want to keep your old number, then simply call your old network, get a PAC code and transition it over.
If you were previously on O2, you can still keep your number but it is slightly more complicated. They won't let you keep your number, so you have to use this workaround. Buy a free pay-as-you-go SIM from any other network and tell your network that you're moving.
They'll release the PAC code, which you then give to the substitute network. Then, you immediately get another PAC code from them. Take that to your old network, and they'll move your number to your new contract. Long winded, but easier than learning a new number!
Can I use my O2 phone abroad?
Like all of the other networks, O2 covers your roaming charges when you're in Europe. Stray out of that area and you will have to start paying additional costs for the data, minutes and texts you use.
Travelling outside of Europe? O2 has a number of different schemes and packages to help you deal with that - you can find them all on the O2 website.
