Most phones have the option to block calls from unknown numbers or from numbers not in your contact list

Open your phone app and check the settings there

@Tan1978 O2 will allow one free number change, but that can cause difficulties for many who use their number for doctor or hospital notifications or for work contacts. Apart from changing your number, there isn't much you can do except not answer the call and let it go to voicemail where you can delete it. You can't block the number if it's being withheld. O2 offers these links to look at:
