nuisance calls

[karen20]

after buying a sim card off the 02 website all I get is nuisance calls off this number 03333440541 she is a rude woman who leaves me voicemails after I blocked her number. the last one she was arguing with a male and threaten to hunt him down and kill him

Sounds like a recycled number.

You should ask O2 to change your number for you Guide: How to change your mobile number

@karen20  If you haven't used the new sim in any phone yet, then it's your number that's getting the nuisance calls. You need to change that one, not the new sim.
