I have our banks app on our phone only in case of an emergency, so if were traveling and something goes wrong and we need to transfer funds from one account to the other we'd be able to do it fast. Other than that I do our bills and stuff at home on our secure network. It helps when hubby is in IT security he makes sure our home router is tighter than Fort Knox.
But even his phone has none been compromised, he is getting these trivia charges into the $100s so he's fighting with his phone provider to get the charges reversed. He has sent stop messages to the company that's billing him but everyday new text msgs from them. Told him he will need to change his phone number. There's always a new way they come up with to take peoples money.
