    Just bought this phone on Saturday.

    No problems until today when AT&T connection was lost. I tried going outside and in the car, walked around with it, etc. but nothing was able to restore the connection until I turned it off and turned it back on, which worked.
    That was around 1:30PM and it just happened again now around 6:30.
    Mobile data is on.

    Any ideas about what's causing this?

    Did the 4GLTE or whatever indicator disappear? Or did it still show 4GLTE but you couldn't access any pages?

    I have this issue on Sprint too. There are a handful of us complaining to sprint reps about it on the sprint forums. One moderator over there seems to think the UICC codes don't match up from the system and they need to fix it. Waiting to hear back on this. It sure if AT&T has something like this.

    The 4g indicator also disappeared along with the AT&T symbol in the top left.

    My Sprint GS5 will be on Spark LTE, but as soon as it goes down to 3G ot never connects back... I will go back to sprint tomorrow and see what the deal is.. very frustrating.... hoping mine was just a bad one, or maybe they need a software update to fix the issue if lots of people are experiencing the same thing.

    This is not really a fix, but you can try to put it into airplane mode and then immediately turn off airplane mode. Should be quicker than a restart

    To make it a little easier, you can try putting the phone in airplane mode, then back out. That will refresh the signal search.

    From what I've read and through personal experience, it would seem that AT&T and Sprint are the worst service providers on the market.

    I experienced this too on Bell Mobility in Canada. I noticed I couldn't open a Web page. I then saw that I had full bars of signal but no data connection. When I pulled down in the notifications bar it said emergency call only where it normally indicates Bell. I went into Settings-Networks then found the listing of the available cellular networks and selected Bell no problem. It's been ok ever since but interesting to see others have it too.

    I have AT&T and no problems. The "AT&T" doesn't ways shoe on any phones.

    Did you try the phone to see if it worked?

    Did you have a circle with a slash mark through it for your signal?

    This. I would have AT&T provide a new SIM card if you're fully dropping service randomly.
