A message keeps appearing in my inbox even though if I take off the sim card.
The Same message keeps appearing in my inbox for hundred times. Even though I deleted the message, seconds later it appears again continuously. And it is really very disgusting for me. Ads keep popping up and even if I press the "back" button of my android phone it won't, neither the "home" button. And what happens next is my phone was hanging. So I was forced to take the battery off without shutting down first my phone. When I turned on the phone, the same happening again. The same message keeps appearing in my inbox, even if I I toggled off my sim card, the message keeps appearing. At that time, I got a feeling that the problem is not on my sim card, but on my phone. Does anyone know what type of problem is this and how I could fix it? Thank you!.
