Re: Need Help with Note 3
Is the SIM card your using active and does it work in another device?
Is this a new Note 3? did you buy it used? If its used is it possible that its been reported lost / stolen or perhaps the person didnt pay it off and the IMEI has been black listed?
I have a note 3 and when i take my sim out it still gets signal, so the red X makes me wonder if its been black listed.
It might be a good idea to contact your carrier and run the IMEI by them to verify its good or bad.
