So I have a problem, I recently changed my phone number which included a new SIM-card. Ever since I switched it, my friends get constantly text messages when I turn the phone on/off. They are complaining and it starts to annoy me too, since it costs alot of money. I checked, I didn't have avast on before, at least I think so. When I log into my account it says no devices connected. So is there a way to remove that? Or do I have to root the phone and completely redo the work with Odin which is pretty annoying?!
