Everyone once in a while, my carrier will send these flash messages to my iPhone. When the message is received, there no alert sound nor any vibration. The screen stays on until I tap on Cancel or Accept. If my phone is in my pocket, I have no way of knowing if I have received these messages and it can be quite easy to accidentally tap on Accept while taking out the phone from my pocket. If I tap on Accept, it will immediately deduct the amount for the advertised "deal" in the message. I think their main idea behind this is to get people to accidentally tap on Accept unknowingly. How do I stop this cheap scam-like tactic?
