I think that my cell phone is being wiretapped. What can I do?

Hello! I've looked through your QA service and I hope that there are people that would be able to help me. Two days ago I've noticed some strange activity of my new Samsung Galaxy. Everyone I've called told me that they hear me with some kind of lag, they hear what I say in a second after I've said the word. Also, my business is going down. That's why I suppose that my phone is being wiretapped. I can't change my phone number and I've already tried other smartphones, result is the same.

Hello, Andrew! 

We at jammer-store have dealt with a couple of the same issues already. In general, we would recommend to you change both your cell phone and a SIM card, but that won't work for you. But there are still a couple of possible solutions. You should check that article, there are lots on mobile phones wiretapping. First of all, due to the signal lag, you probably have an eavesdropping app installed. So, try to check you app's permissions and if you will find something suspicious – just delete it. If that won't work, than, you should check your Bluetooth module. We've heard of some eavesdropping issues, when evildoers used fake Bluetooth headset to wiretap phone calls. In that case a portable Bluetooth jammer will be really helpful.

Than, you should check if there is someone tries to attack your smartphone. You can find more info on modern smartphone's attack patterns at our security blog. And the last possible scenario will be that someone made a deal with your carrier and uses his equipment to wiretap your phone. Or evildoers may use special device that spoofs cell towers. In that case all the information your phone sends and receives goes through their servers. In order to block it – use GSM jamming device and go to cops, they have special equipment and will be able to check whether your smartphone is being wiretapped.
