Service not available Notification

[gulch]

hello,
The past couple of days I've been getting a notification that says "selected network AT&T not available".
I don't have AT&T, I have Verizon,and I am unable to clear this message.
What should my network mode be? it always prompts me to set it to Global.. does it matter which one I choose?

It should be CDMA/LTE/EVDO. Are you rooted? Sounds like you have some other issues going on there.... Where did you get the phone from? A Verizon phone should NEVER prompt saying a AT&T network isn't available....

Where did you get your phone?

Not rooted,and I'm not a power user, wouldn't know how to root
I've had this phone for over a year,and I got it online from Verizon.

Not questioning your experience. I'm just wondering why at&t is showing up also..

The S3 hasn't been out for a year.... Is it an S2 maybe?? Has anyone been messing with it or maybe slipped in a AT&T card on accident.... Do you have any apps installed that didn't come from the Play Store?

Ok... I would verify that the network is set to what I posted earlier.... If the issue still persists I would contact VZW and see what they have to say...... Do you have an AT&T repeater in your home or live in an apartment where someone might have one close? I highly doubt something pushing that signal would cause this but I have seen stranger things happen....

Thanks for your help.
About the repeater,I have no idea, (I live in an apartment complex)
Network mode set to what you said, powered off, and powered back on,and it is gone.
I will post back if it returns, crossing fingers that it doesn't.
Thanks again!

Ok, I'm still getting the pop-up asking me to switch to Global Mode. I'm in Michigan, and never use/need the international ability.
This only happens when I'm at work where my signal is very low. (i work in a machine shop,the building is sheet metal walls and ceiling).
I get this popup if I turn wifi on OR off.
Is there a way to stop this?
Thanks.
