No simultaneous voice and date on iPhone 5?

I mentioned this in a recent post on this thread, I'm experiencing the same issue in the Metro East (Fairview Heights, Swansea area) as recently as this morning. This issue has just croppped up on my device that I've noticed today and I recieved my iPhone on launch day from an AT&T Store. Anyway I did a quick experiment and toggled Data Roaming on (Settings>General>Network) and did a test call to MODOT just to see, and it did seem to revert between LTE and 4G. I was on the way into the office so I'm not sure if this was temporary or not, however it did seem to fix the issue. I believe I left this feature enabled (data roam) on my other devices and only disabled it whenever I traveled internationally. I do not recall ever incurring charges domestically with it enabled. I'd recommend giving that a try. Again, I'm not sure this is the final solution just a suggestion. I'll be stopping by AT&T myself today to either verify this is the cause or see about a new sim card. Good luck!

Turning data roaming on should have no impact on what you experienced. My phone does the same thing and data roaming has always been off. 

Here's my update... I went by the AT&T store on the way home this evening after I was still experiencing the issue. They couldn't find anything wrong either however they did replace the SIM card, and as of right now everything seems to be working. Incidentally there is also an update available to 6.0.1 that may rectify the issue as well. 

Can anyone respond if they are still seeing issues?  Now that 6.0.1 is out as well as some of you who replaced your sims.  Do you see a difference?  Is it able to go from LTE to 4g while on a call?

Not sure what you mean by "Is it able to go from LTE to 4g while on a call?". When you place a call or receive a call, your phone will go to 4g. If you are asking whether an existing data connection will switch from LTE to 4g, yes it does, at least it did in my testing. I guess it kind of depends on what kind of data session you have going. If you are streaming music or video, an incoming call is going to interrupt that anyway. I did not test downloading a file to see if the file continued to download during a call.

thank you for replying sandblaster.  I was just looking for someone to verify as others were having issues using data & voice with the new iPhone when it first came out.  I am looking for things like using mapquest while on the phone or going to safari or checking email.  Thats really what I want the simulataneous data & voice for.  Thanks

It sounds like you've done a lot of troubleshooting on this. I personally have not experienced this issue  but I think it would be a good idea to get you in touch with a member of my team so we can look at what you're experiencing more closely. 

Will you please send a private message to ATTCustomerCare with your name, account number, email address, phone number and the best time to contact you?

Thanks for your note. I sent an email as directed this evening. I look forward to working with a member of your team to resolve this problem.
