For about the past 9 months someone has been able to monitor my phone. They would send my gf a text message via an anonymous texting site saying who I've been texting. They seem to know some of the people but not all of them I've text, some were old gf's. I've never gave anyone my phone info. It seems they can't see the message what I've text to the other people. I hate changing my number.. A friend has advised me to get a new phone and switch to another phone company, all advice wud be appreciated.
