I have Avast Anti-Theft installed on my phone, as well as other Avast apps. Me and my wife switched phone carriers and had to change our phone numbers and SIM cards. I had my app set up to send her a text if my SIM card was changed. After we got our new phone numbers, I changed the number that was stored in my app for her. Apparently, her old phone number has already been given to someone else. That person keeps texting me saying that they keep getting texts saying that my SIM card was changed. I don't understand how they are getting those texts when that old phone number is not saved in my app anymore. Also, my new SIM card number is saved in the app. They apparently get the texts any time I restart my phone. I have uninstalled and reinstalled the app, but it still does it. Can anyone help?
