How do I find out which numbers are O2? Do O2 numbers start with a specific set of numbers? I get fre O2 to O2 calls but I got a bill for £20 for sending too many messages this month so I don't really wanna text everyone to ask what network they're on
Not sure about specific set most netwrosk will have a specific start of numbers but to hthrow that whole theroy out plenty of people will have ported there old number accross networks so there's no real way to tell without asking as what looks like an 02 number could now be on Orange.
There's a downloadable spreadsheet for 07* numbers here: http://www.ofcom.org.uk/telecoms/ioi/numbers/numbers_administered/#pers Obviously not fool proof cos of people taking their numbers with them when they change contracts but it'll be accurate for the vast majority.
