Calls to me from my own number

[BazM]

Hi all,
I have had around 10 missed calls today from my own number!!! Has someone copied my phone number? A little bit worried. It also says I have answered some, which I have not and they have been 5 minute conversations!
Help please!

Take the sim out, clean it gently, put it back and reboot the phone.

You may need a new sim. You can get one instore or by calling O2. All numbers here

Thanks for that, do you know why it has done it? I have read online that it maybe someone has cloned my number.

Having just checked, it does appear to be something called 'number spoofing'

You need to ignore it or ask O2 to change your number.

You are allowed one change of number free.
