Sounds like an interesting problem.
First of all I wanted to make sure you understand that we're not affiliated with your wireless company, we are a separate pay-for-support provider.
If that was not your impression, please state that when you return.
Did someone tell you they lost their cell phone in your home? I also don't think someone is sneaking into your house and charging the phone just to annoy you. If that's happening, you have a bigger problem on your hands. Your phone, if it is near your radio speaker is what is causing that speaker to buzz, not the lost Bravia phone. Cell phones (even older ones) when they are on, frequently exchange data with their carrier, towers, etc. The signals emitted by the phone are strong enough to induct current in speakers and speaker wiring, so you can hear noise from a speaker even if it is off. This can be especially true with small clock-radio speakers. You can stop the annoying buzzing by moving your phone further away from the speaker making the buzzing sound (or you can turn the phone off at night).Bluetooth has a range of 30m (60m in newer versions). I don't know what the population density is near you but if you are in any kind of city with other homes nearby, that is easily enough range to where you are probably seeing a neighbor's phone.
