No simultaneous voice and date on iPhone 5?

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:

  • Network types
  • Status Bar icons
  • Whether simultaneous voice and data are supported (on iPhone)

 

 

GSM networks

GSM networks support simultaneous voice and data on iPhone when using a UMTS connection.

UMTS 4G Yes Appears on iPhone 4S and iPad (3rd generation) Wi-Fi + Cellular with iOS 5.1 while connected to AT&T's high-speed network in the United States.
UMTS 3G Yes  
EDGE E No May be unable to receive calls while transferring data over the cellular network.*
GPRS ° No
* If you cannot receive the call, it will immediately go to voicemail.

 

 

CDMA networks

CDMA networks do not support simultaneous voice and data on iPhone

EV-DO 3G No Can receive calls while transferring data over the cellular network.
1xRTT ° No May be unable to receive calls while transferring data over the cellular network.*
* If you cannot receive the call, it will immediately go to voicemail.

 

 

LTE networks

LTE is available with supported LTE carriers.

LTE LTE No1 iPhone 5 and iPad (3rd generation) Wi-Fi + Cellular only.2
  1. iPhone 5 (GSM model) will switch to 3G for data during voice calls.
  2. Requires a supported LTE carrier. For iPhone, see this article. For iPad, see this article.

 

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.

Notes:

  • Roaming charges may apply, contact your wireless carrier for more information. To avoid data roaming charges, make sure Data Roaming is turned off.
  • 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 does not affect Wi-Fi network connectivity.

Re: No simultaneous voice and date on iPhone 5?

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.

Re: No simultaneous voice and date on iPhone 5?

No your mixing the technologies.  Those are two seprate and differnt senarios.  The LTE (ATT GSM Version) will always fall back to 3G for data if there is a call.  No matter if the data was initated before or during the call.

 

The other statement was for netowrks that don't support it simultanious (ie CDMA), the data is dropped completely for the call if you were in a data session or will not be available if your in a call.

No follow up?

You definitely should have the ability to use voice and data at the same time. 

 

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?

Re: No simultaneous voice and date on iPhone 5?

I don't know how that solution actually is a viable one since it does not work.  like I said the phone does not go down to 3G when on a call. It stays on LTE and gives an error that data can not be used during a phone concall.  This needs to be checked and fixed.

I just got off my second AT&T support chat of the weekend. A ticket was opened after the first session; the tech wanted to find out if there was a larger issue going on. It's obvious there isn't because more people would be talking about it. My second session tonight ended with no progress. The tech tried to tell me LTE isn't in my area even though my phone shows the LTE network. I gave him LTE and 4G speed tests to prove him wrong. I shouldn't need to do that. After that, he told me to wait until my ticket was resolved. This is getting stupid. I'm going to the Apple Store tomorrow, but I can't imagine there's much they can do, unless they want to replace my phone (which wouldn't really address the AT&T problem).

 

Are you in St. Louis, by chance?

Re: No simultaneous voice and date on iPhone 5?

I'm not saying your not having issues.  I'm just trying to think of ways to break out troubleshooting to determine if it would be a device issue, and account issue or possible network issue in your area.

 

The part that should be happening and it's not is when your phone goes from LTE to 4G, it should stay there on 4G so it can use data.  But for some reason it not.  The 4G is dissapearing after a second the then there is nothing after the AT&T.

 

What happens if you turn off the LTE in the setitngs?  

 

Does the phone stay in 4G mode?  

 

Can you use voice and data at the same time?

Re: No simultaneous voice and date on iPhone 5?

I havent tested if it works on 4g only when turning off LTE.  But that is the whole point.  I am getting the phone because it has LTE.  Why would I buy a phone just to disable LTE and drop down to a lesser service?

Re: No simultaneous voice and date on iPhone 5?

The phone is always going to drop out of LTE when on a call because of how Apple designed the chip.

Re: No simultaneous voice and date on iPhone 5?

If it worked that way dwill05 I would not have a problem.  But unfortunately it does not work.  If you have the iphone 5 can you test it for me?  Make a call and then use Data, on LTE.  see what happens
