Hello, I am having security concerns with my phone...I use atnt cell towers....I'm under the impression that cell phone companies use dynamic ip addresses....mine is showing up as static or fixed, and I am in New Jersey however all my logins have shown up as Memphis Tennessee. I thought it might be an issue with my device but I have another phone line with my line of service and the same issue...I search my IP address and it shows as Memphis Tennessee and a static ip address...another issue is my device does not allow me to update, which I read is another sign of my device being hacked, and when I went to update my second device, it constantly kept kicking me off of wifi when doing the update, when my internet service is generally stable...any advice would be helpful....thank you....also my devices are samsung s8, the other device is a Motorola...
