No simultaneous voice and date on iPhone 5?
This doesn't seem right. If I'm taking a call on my new iPhone 5, I'm unable to do anything requiring a connection to the internet. Is anyone else experiencing this?

iOS: Understanding cellular data networks
Summary
This article provides information on GSM, CDMA, and LTE cellular data networks.
Products Affected
iPad (Wi-Fi + Cellular models), iPhone
When a Wi-Fi network is unavailable, iPhone and iPad (Wi-Fi + Cellular models) are capable of using a cellular data network for Internet connectivity.
Select your carrier network technology to learn more about the cellular data network capabilities and features, including:
GSM networks
GSM networks support simultaneous voice and data on iPhone when using a UMTS connection.
voice/data
CDMA networks
CDMA networks do not support simultaneous voice and data on iPhone
voice/data
LTE networks
LTE is available with supported LTE carriers.
voice/LTE data
Additional Information
Cellular data requires an active phone or data plan with a wireless carrier. Contact your wireless carrier for more details.
Cellular data may not be available in all locations, and network speed and connectivity may vary depending on location. Check the carrier's network coverage in your area for availability. See this article for links for wireless carrier support and basic information about the features supported by wireless carriers.
When you are outside your carrier's network, you may be able to access the Internet using another wireless carrier. To use another carrier's network, turn on Data Roaming in Settings > General > Cellular for iPhone; on iPad useSettings > Cellular.

You definitely should have the ability to use voice and data at the same time. Edit - As discussed in this thread; if you're in an area of LTE service, your data use should shift to 3G.
Do you get an error message or does it just time out?
Have you done any troubleshooting like restarting your phone or resetting your network settings?

I have restarted the phone several times.I just tried restarting the network settings and have the same problem. If I place an outbound call, I'll see 4G replace LTE at the top of the screen very briefly. When the call is in progress, 4G disappears and nothing is shown in its place next to the word "AT&T". The error message I receive says: "Cellular data connections are not available during this call." Under General > Cellular, Cellular Data is on, Enable LTE is on.

INterestingly enough I have tested this on 2 new iphones, both family members, and the same issue arises. This was what I was afraid of and kept me from buying the iPhone 5.
Not sure what the exact issue is, but it might be a combination of Apple & AT&T.
If any one knows how to fix please let us know

It sounds like your calls are falling down to the 2G network, which doesn't allow similtaneous voice and data. I'm not familiar with your available settings options, but do you have 3G enabled on your phone?

I'm in St. Louis. I don't have an option to enable 3G in iOS6.

In iOS6, the only option is to enable/disable LTE. 4G (HSPA+), 3G, and EDGE are on by default, unless you turn off all cellular data.
They do claim the on the AT&T network, the phone will fall back to 3G when in an LTE area, but how does that actually work? If you initiate or receive a voice call, does that automatically drop everything back to 3G, both voice and data, even if your aren't using daa at the time? Or if you are on a voice call and then try to use data while in an LTE area, does that then drop everything back to 3G? If it's not working, the transition may not be working right.

When using a cellular data network that does not support simultaneous voice and data, incoming or outgoing calls will interrupt cellular data transfers until the call ends.
This seems to imply that if you are transferring data over LTE and a call comes in, or you start one, it won't drop to 3G.
However, this says:
iPhone 5 (GSM model) will switch to 3G for data during voice
Which states the opposite, unless it's limited to just starting data transfer during a call, although it doesn't say that.

I contacted chat support and didn't accomplish much. They are going to open a ticket to see if there's an unreported outage or other issue. If this is a larger problem specific to St. Lous, I would have expected more people to complain about it. Getting this phone going is proving to be a very time intensive process.
