Hi, I recently just activated the Note 3 to my account and it seems i keep getting random SIM Card errors, Firstly i get an error saying that "The device didnt respond in time" Sim Locked" or "No Sim" restart my phone. I have no idea whats going on with it, I even had to turn on my wifi just for the phone to activate, the weird thing about it is that it shows the "No Sim" in the top right corner of the phone, but it still gives me a 3G signal, Just wondering if there is a fix to this, because I am paying for premium data and cannot even use it. I have been to the sprint store and swapped my Sim Card out 4 times in 2 days. Is their a fix to this? can u open the sim tray and fix it the thing is that my phone actually recognizes the sim and everything i can see the imei and the iccid clearly when its powered on then its give the errors and iccid goes away but imei and 3g connection is fine. I need some help PLEASE!!
