Malicious mobile number?

HELP!! I have a friend at work who has a malicious mobile number that has been sending her nasty texts and pranking her number with calls. It is worrying her sick. I haven't a clue who it is although I do know it is a Vodafone mobile after trawling through the internet. Vodafone won't give details because of Data protection. Is there any way I can find out who it is other than contacting the police for her? I have checked the net for reverse number search but all the sites want payment up front for the search - some are £150! I am sorry if it sounds stupid but I have no faith in the police anymore - I really want to find out who is sending her these nasty messages and spoofing her phone while she is at work. If I don't get any joy then the police will have to be the next step but I am hoping somebody out there might be able to help us? Thankyou.

Malicious mobile number?
Yup, call your cell phone provider, and ask them to block that number. It won't cost you a thing, and it's worth it to save yourself from the aggravation.





There probably isn't a way to find out who it is without paying, as far as online stuff goes. IF someone calls 3x or more during a day with harrassing phone calls, you can file a report with the police, and they will do their part to try to figure out who the culprit is, so they or you can press charges against them.

Phone the number from a different phone, and try and find out who it is this way.





And go into Vodaphone and show them the nasty texts .... force them to act. She shouldn't have to put up with this.

Reply:You can ring your phone provider and ask them to block the number. That means the person cannot send you anymore texts.





Otherwise right down every message and the time and date and then take the list to the police. If they are threatening the police have to check into it.
