I just got a Samsung S3 a week ago. I have received calls and texts on it, but it appears that I am missing calls. Somebody tried calling me 6-7 times in a row in a 30 minute time span yesterday and it never rang, and only one of those showed up as a missed call. Today, the same thing happened again with two calls, and neither appeared in my missed call log. They sent a text and it didn't appear until about 20 minutes after it was sent.
I live in a built up area where there should be good coverage, and looked at the map and am rated as "best coverage." In the past six months, there were maybe two incidents at most when my old phone (not a smart phone) did not ring. I have a normal amount of bars on my phone.
During both of these incidents, my phone was not in use, and the ringer was on with sufficent volume.
Does anybody have any recommendations for solving this?

I got this issue fixed. You dont have to remove the battery or even restart your phone for that matter. This problem occurs mainly because of 4G LTE. I dont know if its the phone or the service. So, I have found an alternative.
What you need to do is add a new APN and run your device on 3G so that you can still get calls and browse until att or samsung fixes this issue. You can either use 4G toggle which you can download from google play to toggle between 3g and 4g. Or you can add as I have said above the new APN. Please go to Settings -> More settings -> Mobile Networks ->Access point names-> (+ new APN) . Give the Name of your choice but the APN should be defined as wap.cingular and finally save it. Change the existing apn to your newly created apn. Go to you home menu and you will see the 4G is used insted 4G LTE. You can even check your speed by using speed test.
Actually now I even have fewer dropped calls and I get the calls as soon as they call it.

We are researching this but I have marked jan_raghavan's suggestion as an Accepted Solution for the time being because it's worked for a couple people.
I have to note that this is NOT an AT&T solution and it will limit your capabilities on the device because you won't be on 4G but since it's helped a few of you, I want to make sure it's visible.>

After talking with ATT support, it seemed like the best idea was to have ATT drop me back to 4G ( no LTE) They can easily do this. Now I have some documentation to go back to ATT with, and ask for compensation for not having LTE capabilities; even though I am being charged. for them. Best case scenario is that when ATT finally comes up with a fix to allow full LTE and no calls just showing up in VM, they will come up with a reasonable and fair credit for the time not having LTE and the vast number of time consuming calls made to tech support trying to get through to them that there is a problem. I think the word is finally getting to tech support that there are issues. If you call tech support and they do not know what you are refering to, tell them that you believe that there is an issue with the service in your area not switching between, LTE and 4G. This may or may not be nation wide, but only in specific regions. I believe that they are working on the problem, but I would not expect and immediate solution

AT&T customer service called. Said that they were aware of the problem with LTE and Android but had no resolution. They are sending a new SIM card to just have on record that they tried. I told her repeatedly to check this thread. She was unaware that it existed and refused to write it down, so I read it into the 'recorded' version of the call and also pointed her to the IM threads from three previous sessions which she said she didn't have access to.
I've been testing a work-around since the network monitor I've installed shows that every voice call switches the network from LTE, 4G to UMTS, 3G. When the call completes, it switches back to LTE, 4G. 1% of the last 48 hours, it has switched to HSPA+, 4G then back to LTE, 4G.
The work around is that I've enabled the AT&T mobile data even when I’m on a solid Wi-Fi connection. It appears that the mobile data connection is necessary to manage the network switch since about 100K in data network traffic happens even when I've got a solid Wi-Fi connection to manage the switch between the 4G and 3G networks.
Since I'm on a 300M data limit, the AT&T rep said that AT&T would compensate me for any overage in network usage for leaving the mobile network on. Others who are having the issue might want to try this work-around. But since if someone calls, the phone doesn't ring and if they leave no voice mail, I can't tell how mad they are until I get a second call that goes through or a text or an email, I'm not sure this work-around works. But so far, no missed calls since making this change, or at least none that I know about.

What are the 13 markets that are affected? I live in South Florida and there is a brand new GS3 waiting for me at home to replace the GS2 that is having an issue of shutting itself down when it's idle and the battery draining and you never know you've missed calls, since an over-the-air update in December.
My father has stage 4 kidney disease and I just can't miss a call in case I'm needed. Please tell me if any of you experiencing this problem live in South Florida.

NoStuff -- could you explain how to "enable mobile data" even when on Wi-Fi?
In general, how does WiFi status affect the problem that people are experiencing? Do missed calls occur when on Wifi? When not on Wifi? Does it matter?

In my case, my radios (WIFI and DATA) are always off unless and I use them on demand. With both radios off, my phone still would not permit calls/texts to come through. The fix of using a code through the dialer has stopped this but I am not utilizing the LTE phone and network I am paying for.

and that is exactly why this thread is about.
thats what weve been trying to get att to do...
since were paying for it

bztips - you enable 'mobile data' in Settings - Data Usage then check Mobile Data.
Since making this switch, I'm not having the problem with calls not ringing.

Just to add another market it is happening in is Michigan. It is happening to a few of my friends also. I'm so fed up with this crap that I'm willing to cancel all of my contracts, sell the phones on eBay to pay the cancellation fees and switch over to Big Red. I just read today that ATT is going to expand it's LTE network to LTE Advanced in the second half of 2013. What a joke. They can't even get the original LTE working, so what good is the advanced going to do?

AT&T is aware of the issue and we have begun working on a resolution. We continue to investigate reports of customers not able to make or receive calls. We hope to resolve this issue in the near future.

My GS3 has been repeatedly dropping calls and missing texts. Three calls to AT&T customer support have "resolved" the issue, only to have it re-appear days later.
I've absolutely had my fill with this. There is NO REASON for this to happen. If you sell me an LTE device, the implication is you'll have a functional LTE network for it. I'm this close to paying an early termination fee and switching to Verizon. I don't care about the cost - I need a functional phone, and AT&T has failed to provide that.
Fix this NOW, or you'll lose a loyal customer.

To add my 2cents worth, My cell is an extension of my office phone. Working from home or on the road, my cell is as critical as my office phone. My company requires the use of ATT for Cell service (and they also pay for it). I have a S3 running 4.1.1.
My problems include
90% of the time, I am in my home office with my cell connected to my home WiFi. Missed calls are seen when a Voice Mail is received, but the cell did not ring.... UGH.
Looking forward to 1) a resolution and 2) the upgrade to 4.1.2

How is it possible that they are "AWARE" but every time i call they blame me, my cell, google, everyone but admitting there is an issue.
oh, and thats after me trying to convince them for 45 minutes that there is a problem....
dont just say" they are aware" show us where it is posted that ATT is officially recognizing an issue and working on resolving it....
