Device "forgot" my phone number, IMEI out of the blue, can't make calls etc.

I have a Samsung Galaxy Note 3

(Model number SAMSUNG-SM-N900A)

Build number LRX21V.N900AUCUEOC2

Android version 5.0

on AT&T...

 

I've had it over 6 months it worked completely fine then today someone tells me they're calling me and it goes right to voicemail. I notice I can't dial out either.

 

Upon looking in the settings I notice the device is coming up Baseband version unknown, Mobile network type unknown, Network unknown, service state out of service, mobile network state disconnected, My phone number unknown, IMEI unknown , etc.....

 

I've restarted the device, waited, turned it back on, nothing changed.

Dialed *#06# it comes back IMEI null ....

I've taken the battery out, removed the sim, waited, reinstalled it and powered on with no luck.

I ran an anti-virus and anti malware program nothing seems to have caused a problem that way and I have no idea how this happened...

I've also tried to do a software update and I get the message "DM initialization is not ready. Check network or SIM card."

 

When I try to dial out it says "out of service area" followed by "mobile network not available."

It's not a service issue because I'm downtown in my home in a major city and have NEVER had any service issues here before.

 

I read an article about restoring null IMEI but it was super detailed and I figured I would ask around before going into the command mode of my phone as the article suggests to do.

Can anyone help me?

The first thing I would do is go to an AT&T corporate store and get the sim card replaced.

Thanks. Of course I'll eventually do that if I must, but it will be the last thing I do once I determine I can't resolve the issue on my own.

I would highly recommend you do this first before trying to solve any other problems. It could resolve ALL your problems. It doesn't cost anything to get a new sim card.

So are you saying I'm wasting my time doing research online, posting this question, restarting my phone and all that? I should've have just went into the store right away?

I didn't say you were wasting your time, just gave you a suggestion to try before getting into the internal software of your phone and messing up something that you can't fix.

Another suggestion is to go to a Best Buy store that has a Samsung Experience counter. They can trouble shoot your phone and flash it if needed. If it is only 6 months old it is still under warranty, you messing with internal settings could void the warranty!
