It started with my iphone 4s back in 2013. My ex gave me a temporary tmobile sim card to use while overseas in the UK (i live in the US). He has been monitoring me ever since. I have tried everything with the phone to stop being monitored until I finally cut the phone service and am now using a burner (cdma). now i have reason to believe he has had access to all the devices in my home since that time in 2013 (laptops, ipod, ipad, computer, my siblings smart phones). he has access to my siblings devices because we have a family plan with tmobile.
now what I am asking is if anyone knows how he can still be spying on me all the way from UK?
I was told to change my router password which i did. i have a dual router/modem with comcast.
I dont think the issue is with the wifi becuase he is way out of range. Could it be that he has access to some ports? or would getting a whole new router/modem help since i cant change its ip address or MAC address?
and changing the ip addresses of each device i and my family use wont work bcuz he gets notified of sim card changes, mobile number changes, password changes etc.
