Could someone tell me if these notifications I am getting or legit I keep getting ones come across my phone from the Chrome app that says my phone's been infected with a virus and my SIM card is about to be shut off and download this mess and do this or that and I haven't done it I'm just wondering if these messages are legit messages or if it's a scam? Please help.
Your phone is probably compromised but do not download any app that alerts you to a virus. Is Google Protect does see any issues with your apps, just make you clear cache partition or find a way to backup your data then reset the phone.
Probably a bad or compromised site you visited in chrome. Might try clearing chrome data. Usually it's a bad cookie hanging around. Try deleted recent history and or cookies first before deleting all chrome data.
