Hi, my daughter is receiving anonymous calls, texts and strange voicemails, I would like for her mobile number to be changed if possible? How can this be done?

Hi @Lislou
Welcome to the o2 community forum
Very sorry to hear that your daughter is receiving worrying calls.
I believe that you can change your mobile phone number once free with o2. Guide provided by Member Cleoriff for you.
Good luck and trust all goes well quickly.
