I don't need to ask something when I already know what the answer is. Simultaneous voice and data works just fine on a properly provisioned AT&T iPhone on Verizon.
I am not attacking you, you are being extremely hostile and attacking me. I am simply stating facts, which you continue to ignore, even though you have been informed of how the AT&T iPhone works on Verizon. If your simlutaneous voice and data doesn't work, it has to be a setting or provisioning problem on Verizon.
We know the following facts:
1. AT&T iPhones work on VoLTE on AT&T.
2. AT&T iPhones work on VoLTE on Verizon.
3. Verizon uses VoLTE to deliver simultaneous voice and data.
4. An AT&T iPhone on Verizon must use VoLTE to make any phone call, since it does not have CDMA.
Therefore, any problem with simultaneous voice and data on an AT&T iPhone on Verizon is a settings or provisioning problem, since the hardware can do it, the network can do it, and we know VoLTE works.
You continue to deny these objective facts, and obfuscate with ridiculous and patently false statements. Get your story straight.
So when you're wrong and want to continue changing your story, making things up, and arguing nonsensical points, you just go and report people? That makes a lot of sense.


Instead of going on a forum, complaining, making factually incorrect statements, and then changing your story over and over again, how about you dial up Verizon and figure out why your simultaneous voice and data doesn't work, if that's even the case in the first place? If it, in fact doesn't work, which I don't really believe one way or the other at this point, then they need to know about it and work to fix it so it doesn't happen to other LTE-only phones or Intel iPhones. You may need to push them hard to get to someone who knows how to deal with LTE-only phones, and the IMEI range of AT&T/T-Mobile iPhones, as there are probably very few on Verizon. But you need to have your facts straight first, which you stubbornly refuse to do, even after having the facts clearly laid out in front of you.

Yeah, that's a fair point. Before Grimham started posting factually incorrect nonsense about the Intel iPhone's simultaneous voice and data capabilities on Verizon, I posted a full a nuanced view in post 13 with all the various details of the pluses and minuses of an Intel iPhone on Verizon.
Correct. Some roaming gets worse, and some gets better. I don't know if they have any LTE roaming without VoLTE, but it's certainly possible. I roamed on AT&T LTE with Sprint, and had no voice service, which was really weird.
[doublepost=1531610200][/doublepost]Remember also that Verizon is shutting down CDMA on December 31, 2019, so we're less than T minus 18 months. I don't know if they will keep a CDMA back-end up for roaming, or if all CDMA roaming goes down as well, and they flip over to VoLTE and HSPA+. My sense is that CDMA's demise is an inevitability now that Verizon is planning to go off of CDMA, it's just a matter of whether they let CDMA roaming live on for a few more years beyond the end of their own CDMA network, or if they are pushing partners like USCC to get their stuff together on deploying VoLTE. Unfortunately, because Verizon never deployed HSPA+, they will lose some extreme fringe coverage for voice/text, but will have more functioning data coverage than ever.
