Selling phone .. what should I do first

[Anonymous]

If you sell does the buyer need to buy a new sim card.  Should I remove my SIm

Of course! Your phone number is on the sim. Probably all your contacts as well. You should remove your sim and do a hard reset to wipe the phone.

Which phone are you selling maybe we could guide you through what to do

Also de-register it if it's required by the handset. Typically you do this with iPhone and possibly Blackberry (although I'm not sure). With Android you can remove a device from the account it was used with.

If it's an iPhone then the association with the Apple ID needs to be sorted to remove the activation lock that now comes with iOS 7.

Until we know more from the op it's hard to say anymore.

sorry for ps again! .....if i buy an iphone 4s which is unlocked and put in my 02 sim will it work okay? and does the same apply if its on 02 network when i buy it?

Yes just pop your sim in if it's the same size. Back up your old phone to itunes.

Connect your new phone and choose select from backup and all your data, photos and contacts will swap over.
