Malicious, hoax, nuisance 999 calls and messages can be offensive, threatening, annoying and may even cost lives. They may result in your service being suspended and can be a criminal offence.
If you receive a malicious or nuisance call and would like advice, contact your Service Provider if you have a Pay Monthly mobile phone. You'll find their number at the top of your bill. You can also get help by dialling 100 from your O2 mobile phone.
If simply contacting your Service Provider does not solve the problem you should tell your Service Provider to contact the O2 Nuisance Call Bureau. A specially-trained team of people there will be able to offer further advice and assistance on dealing with the problem. They may decide to apply a tracing facility to your mobile phone number. Almost all malicious calls can be traced and we'll work closely with the police* to provide them with all the information they need to investigate your case further.
If you have a Pay & Go™ mobile phone you should either contact the police to report that a crime has been committed or customer service who will pass your details to the Nuisance Call Bureau if further help is needed.
* Please note that we have to give information resulting from our investigation straight to the police. We cannot give it to you directly.
