When I got my Nexus 5 back in 2013 I noticed that if I was on LTE and made/received a call the data would switch to H and then switch back to LTE after the call was ended. My Nexus 5X does the same thing. What's the deal? Before I had the Nexus 5 I had a Galaxy SII Skyrocket(the LTE version of the Galaxy SII from AT&T) and that phone would stay on LTE during calls and that was from an early LTE phone (the first AT&T offered). I would expect the same from a current phone in 2015.

It currently says "TURN OFF VOLTE PROVISIONED FLAG" so I'm guessing it's currently on. However I'm not sure what this has to do with anything. VoLTE means "voice over LTE". I'm not even trying to do voice over LTE. I'm just trying to use LTE for regular data while on a call over regular GSM.

That is exactly the case if you want to stay on LTE while on a call, then it is called VoLTE(Voice over LTE). Your setting for that seems to be on...
Things to try, unless Nexus 5X on AT&T is unable to do VoLTE, ask AT&T.
Test with T-Mobile sim
Check APN settings

Everything I've seen says that VoLTE means that the LTE data connection is used to actually make phone calls instead of the traditional cell voice network(GSM/CDMA). I don't care about that. I'm fine with regular phone calls using the regular GSM voice connection. I just want to be able to use the LTE connection for things like browsing while I'm on a regular phone call.
Good to know that it isn't an issue with the phone. I guess it might be an AT&T network issue but that would be strange since it worked with my old Galaxy S II Skyrocket that I bought in 2011. Maybe a compatibility issue between AT&T and this phone? I'll see if I can test with someones T-Mobile SIM. My SIM card is only a month old since I had to get a Nano SIM when switching from my Nexus 5(which took a Micro SIM).
The only way you will be able to use LTE to browse the internet while on a call is if you are placing the call using VoLTE. Before VoLTE (and currently if you don't have it) your phone will always drop to a non LTE connection.
I'm sorry but that's just the way it has been and the way it is. Every device that doesn't use VoLTE will change to a different non LTE signal to place the call.
AFAIK, VoLTE on our device does not seem to be supported on the "gsm" carriers.. Yet.
Maybe try out the Network app? It allows you to specify a network preference and do a bit of fine-tuning.

That might be the case with the Nexus 5 and Nexus 5X but it was absolutely not the case with my old Galaxy SII Skyrocket. Kind of strange that the Nexus 5 and Nexus 5X have this issue.

I didn't realize VoLTE was a feature of phones in 2011. I'm wondering if maybe AT&T stopped supporting it on its network? Oh well, thanks for the info. I didn't realize a phone had to be able to make calls over LTE to be able to use LTE data while on a call. It's also surprising considering how Verizon does simultaneous voice and data. Once Verizon started supporting LTE phones(several years ago) you could do simultaneous voice and data but it wasn't(at least at that time) using LTE for voice calls. Just for data while a CDMA call was active. I guess it works differently for GSM?

In any case in order to stay on LTE and use data, your phone has to support VoLTE, because normal LTE is data only and when you make a call it would drop to 3 or 4G. CDMA and GSM are 2 different type of networks. I was always using GSM providers(T-Mobile in my case) and this is how it works. I don't know how your old phone could let you be on LTE during a call - unless AT&T was using some proprietary service.

Early on, phones had a separate 3G radio from their LTE radio. This is a big part of why the first LTE phones had substantial battery drain issues compared to 3G only phones at the same time. One of the nice things about the setup was that you could use 3G for voice and LTE for data simultaneously. With the move to integrated modems, which significantly improved battery life and speed, that feature was lost. Until AT&T implements a standard for VOLTE like T-Mobile has you're going to have to deal with the lower speeds while on a call.

OK that explains it. The Galaxy S2 Skyrocket was the first AT&T LTE phone so it probably had separate radios. I'm also kind of concerned with what VoLTE will do to battery life. I remember that one of the ways phone matters were reducing battery drain was to keep the radio asleep unless it was asleep. With VoLTE the LTE radio would have to be active all the time. Has the energy efficiency of newer LTE radios made that a non-issue? How is battery life on T-Mobile vs AT&T using the same phone under similar conditions?

The technology in LTE networks doesn't handle voice transmissions it only does data. So when you place a phone call on LTE it’s actually rolling back to the carrier’s older network to use CDMA tech to make the call.
I'm on Verizon and I can do both at the same time. I just tested it.

So you are on Sprint? It all depends on the carrier too, I believe. If I remember right, AT&T used to be the only one that could do that that I knew of.

If you used the Evo 4G it may have been connected to data via 4G, which is not the same as LTE. You can do the same with LTE being connected and voice calls. However it can't be done with 3g and voice as they use the same radio and like the above post says no US carriers have that technology. The only reason 4G and LTE works is becase they are data only on seperate radios. Of course it could have been magic.

Its not a difficult concept. Your data connection is being cut off because you're on a phone call. You might manage to post (something that can be done on even the slowest weakest connection) but something as intensive as downloading is always going to be interrupted.
063_XOBX is mostly correct.
the CDMA GN has a CDMA radio and a LTE radio. if you are not on LTE and you get a phone call, your data will shut off.
most HTC phones (esp the EVO) have a radio chip which allows data and voice at the same time as there are 2 CDMA radios in the phone.

To correct something I saw on this thread (and to complement previous commentaries):
- LTE is considered to be a 4G technology
In March 2008, the International Telecommunications Union-Radio communications sector (ITU-R) specified a set of requirements for 4G standards, named the International Mobile Telecommunications Advanced (IMT-Advanced) specification, setting peak speed requirements for 4G service at 100 megabits per second (Mbit/s) for high mobility communication (such as from trains and cars) and 1 gigabit per second (Gbit/s) for low mobility communication (such as pedestrians and stationary users).[1]
Since the first-release versions of Mobile WiMAX and LTE support much less than 1 Gbit/s peak bit rate, they are not fully IMT-Advanced compliant, but are often branded 4G by service providers. On December 6, 2010, ITU-R recognized that these two technologies, as well as other beyond-3G technologies that do not fulfill the IMT-Advanced requirements, could nevertheless be considered "4G", provided they represent forerunners to IMT-Advanced compliant versions and "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed".

Voice and data at the same time have been available since Verizon brought out 4g LTE service. If you're in a LTE service area (most of the country with Verizon).... Then voice goes over the old CDMA network and data is on lte. And you can use both at the same time.
VoLTE is different, and is being rolled out to devices.

Only on Android devices (most, not all), and only because they built a "dual" antenna/radio setup on the snapdragon chipsets. But for whatever reason on the new X and Turbo, they went away from that. So the only way to have that function again is with the somewhat unreliable VoLTE.
Thanks for confirming the Note 4 still can...

It's due to the antenna setup.
In order for voice and data to function simultaneously on Verizon without VoLTE, there has to be two separate antennas - one for CDMA and one for LTE. Some of Verizon's recent devices (such as the Note Edge and Droid Turbo) only have one shared antenna, meaning that only CDMA or LTE can run, not both. It's certainly frustrating for many users, and while Verizon's reasoning for this makes some sense, it's still not great at this time for those who use the feature. With the network moving toward LTE-only with VoLTE, Verizon's reasoning is in part based on this - why include additional hardware at additional cost and space (a second antenna) to run voice and data simultaneously when the same feature can be achieved with one antenna and VoLTE? Of course, VoLTE isn't completely ready for prime time, and they're still working out issues, so for many it's not a true replacement at this point. But that's a big reason why some of Verizon's recent phones can't do simultaneous voice and data without VoLTE - Verizon is trying to pave the way for VoLTE adoption.
Which NEW phones support Voice and Data (WITHOUT) using VoLTE... I have a 2013 Moto X that supports this, and refuse to upgrade until I can find a new device that does support this -- where can I find this data? I would imagine some phone (like a Nexus 5X) might support this since it's not made specifically for Verizon? And before it gets asked, VoLTE is too unreliable for my needs --- when using it on my work iPhone 6S calls drop constantly, so I've had to disable it... but still need voice AND data at once.

Hey guys, I asked awhile back about switching to ST and I've done it. I finally got data working by using a TMO SIM, but I can only get EDGE, no more, no less. Even in relatively large cities in my area that have TMO towers, I only get EDGE. My question is, is there anything I can do to get better data?
I have Verizon LG G4 on Straight Talk Verizon Towers and everything works great! Not sure what your issue is. Only issue I see is when I make a phone call, it drops to 1x always

That's because you're not using Advanced Calling (VoLTE). On Verizon's network, calls always drop to 1X unless you're using Advanced Calling. In the past, most Verizon phones didn't indicate this. They would continue to show whatever data connection the phone had (3G, 4G) even though the call was being done over 1X. Several recent Verizon devices have been more honest about which networks are actually in use, including the G4.
So, what you're experiencing isn't an issue. It's what should be happening.

That's because you're using a Verizon ST SIM, the OP is using a T-Mobile ST SIM. Also, you need to enable Advanced Calling on your account and your phone to use voice and data at the same time over LTE.
To the OP, I have the same problem. When I put my T-Mobile SIM in my VS986 I only get 2G at home, while LTE only works in the older LTE sites that are using band 4 primarily. Most 2G > LTE sites are using band 2, which according to the Verizon spec page this phone supports, but it must not be active as it doesn't work. I've been looking at ways to enable band 2 without any success yet.
To the OP, you added the APN configs for Straight Talk T-Mobile, correct?

I just opened a thread asking about VS986 wcdma bands availability. I was reading LG specs and they say this phone has no 3g, just 2g and LTE. Reading in many other web pages they say this phone has all 4 wcdma bands available. Maybe they are software locked?
I think, I made a mistake buying this phone to be used in a GSM network. Have you checked with Verizon/Tmo rep?

What are your LTE speeds like? I thought about making the switch but then I read that Verizon limits LTE speeds on ST to 5MBPS...Is that true? As it is my 3g+ speeds end up being faster than that most of the time.

I'm getting better than 5Mbps, but definitely shaped/limited bandwidth. If you actually use 10Mbps+ regularly, keep shopping.
I read there are some issues with the Galaxy S6 and some newer phones on Verizon being unable to do native simultaneous voice + data. I think because of a limit of the # of radios and/or antennas. What can we expect with the 5X on VZW? Thank you!
All new phones can do simultaneous voice and data only with VoLTE or while connected to WiFi. When connected to LTE (and no VoLTE) or 3G data they will drop to CDMA 1X if a call comes in. This is because they only have one antenna pathway and one radio. If they had a separate radio for LTE (like done older phones) it would drain battery almost twice as fast since mobile connection is one of your larger battery users.

Ugh, what I feared. How do people do Nav and have phone calls at the same time? Is this going to work with VZW VoLTE on day one? May have made sense to design with two radios and two antennas and only activate the second one when necessary?

Any time LTE is on the second would have to be on, or it wouldn't be able to seamlessly take the call, so that wouldn't have worked.
If your call isn't very long navigation would still work fine, it caches a bit in case of signal drop. The other option would be to download the route ahead of time, Google can do it now I think.
I have a feeling it should have VoLTE though, which would give you voice and data.

Will the same limitations be on each carrier (ie. if I switch to AT&T I still need to use VoLTE for simultaneous voice + data)? Thank you!!

Nope, the way GSM and CDMA works are different. Say you don't have VoLTE and are on an LTE connection. The tower also has a spot for you on HSPDA and GSM if on Tmo or AT&T, or on CDMA if on Sprint or Verizon. If you get a call you fallback to HSPDA or GSM. A similar thing happens on CDMA. The difference is CDMA can't do voice and data on the same connection, GSM and HSPDA can do both.

Really wish phones included a Ev radio so this would not be an issue. I wonder if the voice quality/codec on AT&T has improved over the years? Last I used them their voice quality was far inferior to VZW. May be time to consider a carrier switch.
I've not had problems with voice quality, the few times I call on AT&T. They weren't as good as Sprint (their new network has simply amazing voice quality, and data was OK lol).
Mostly I use Google voice via hangouts to make calls, so the network data is more important then voice quality.

How new? My S4 gets simultaneous voice/data on lte, but not on 3g. Are you sure you're right about this?
Well, the S4 is not a new phone. And yes I'm certain without advanced calling (or VoLTE) you will not have voice and data on LTE at the same time.

Something I'm just realizing...I have a lot of friends and offices that have cell phone amplifier / extender systems that only repeat 3G not LTE. With no 3G radio this phone will be only able to do 1x for voice/data?! I think its also crazy that pure data devices such as the MiFi/personal hotspots still include ability to do EvDo Rev A yet phones don't!

The S4 had extra antennas unlike the newer phones because of VoLTE. The S4 had both radios on at the same time which eats more battery on a call with VoLTE you have improved battery life during a call and do both at the same time. The move was intentional to save costs as well as battery life in the long run.

I just got my Nexus 5X up and running on verizon. With my Galaxy Nexus I was about to take a phone call while tethering, but can't do that on this phone. Is there a fix for this? It's kind of a bummer because I tether often and take phone calls.
Edit: (12/18/2015) I figured it out. Chatted with VZW tech support to enable HD voice feature, and made sure "enhanced LTE mode" was on in settings. Voice+Data work simultaneously now!
Update: (1/19/2016) I have still intermittently had issues with simultaneously voice+data. I started to wonder if it could depend on who you are calling or what tower you are connected to. I powered down my phone and pulled the sim card for a few seconds, then rebooted and it worked again.
I'm wondering if anyone else is or has been experiencing this issue. For the last couple weeks my black Pixel 2XL 128gig on Android 8.0 is having a problem switching from LTE to HSPA when trying to make a phone call. I've been on the phone with both Google and AT&T numerous times. ATT deactivated and reactivated my sim card. I ended up getting a new sim card and still didn't fix the problem. Google eventually sent me a brand new phone and I'm still having the same problem. Now Google wants to send me another new phone. I had the original pixel XL on ATT and did not have this issue at all. Anyone else having a similar issue?
Uh... Yes, that's normal, you don't have VoLTE enabled. There's a whole thread about enabling it with AT&T here on the boards. TLR of that thread, download the Oreo 8.1 beta, enable VoLTE in the software, talk to AT&T to enable enhanced voice features.

You may need a new sim card, I had similar issues, visited an AT&T store and it was fixed within five minutes.

I did get a new SIM card. Still was experiencing the same problem. I updated to 8.1 beta to and enabled enhanced LTE to see if that fixes the issue.

Then somehow you had VoLTE on your first Pixel. Without VoLTE, the phone will 100% of the time kick back out to HSPA+ when you make a phone call. That's been the case with every phone I've owned prior to VoLTE and actually having a phone that had and made use of VoLTE.

I know it's supposed to kick back to HSPA when making a phone call. The problem is that it doesn't. Instead of going to HSPA I lose signal completely. The phone will try to make the phone call and then the phone will manually hang up like I hit the end call button but it does it automatically. Then I either have to toggle airplane mode or reboot the phone to get LTE again.

Ah ha, your original post didn't make it sound like that. In that case, maybe try a new SIM card?
Edit: Re-read the first post and you already tried a new SIM. Have you tried a SIM from someone else, maybe on another Network to see if it's the phone or the network?

Ya I got a new SIM the other day. I talked to jcase about it and he believes it's a provisioning issue on AT&Ts end. I was just wondering if anyone else has experienced this and if they found a solution to it. I did end up upgrading to 8.1 beta and that obviously fixed it because of enhanced calling. It's just weird because I haven't found anybody else who has had this problem.

One thing you should always try before going to the provider is a safe mode boot. I tried a new rom and could not get data. Most things worked but no data. I could call and WIFI but no cellular data. In safe mode I got data. That tells you some third party APP is responsible.

What does VoLTE have to do having LTE data while on a call? I don't see any reason why you couldn't have LTE available for data even when it doesn't support LTE for voice calls.
I've had LTE switch to H every time I've made a phone call on my Nexus 5, Nexus 5X and Pixel 2 XL. Since 8.1 I've had VoLTE. I know because when I make a call I see the "HD" which is VoLTE but the LTE still switches to H so it seems like the two are related.

Uhm, everything? VoLTE is Voice over LTE which implies that you have an LTE radio connection (as opposed to a UMTS/WCDMA/HS*PA radio connection).

That's because you don't understand the fundamental way in which cellular networks work. Don't feel bad - you're not alone; it's a complicated topic.
The radio on your device can only support one type of radio connection at a time. There are a multitude of reasons for this: capacity on the chip, the need for multiple amplifiers to work simultaneously (because typically carriers use different parts of the radio spectrum for one Radio Access Type than another), antenna capacity etc. Keep in mind that are scenarios in which your device is already juggling quasi multiple radio connects, e.g. carrier aggregation.
Don't get me wrong, there have been devices that supported multiple simultaneous radio access technologies on a single device, but that's because they had multiple radios. These were older devices on IS-95 CDMA carriers such a Sprint when they were pushing WIMAX, and even I believe some Verizon devices which allowed them to do multi-RAB for simultaneous voice and calls before their CDMA infrastructure was upgraded to allow this (and prior to their VoLTE launch). These devices are few and far between.
One last point on this topic: the network handles handover between RATs (though it's possible for the device to only support one RAT). If you were allowed to have simultaneous connections to two radio access types, the network would be juggling twice the resources for your device (the transmit and receive portion of a data connection or call is not the only resource involved). This is yet another reason why in most circumstances you'll never see two simultaneous RATs for one device: it costs the network money. Unless you're trying to cover up for a deficiency is your network architecture (e.g. IS-95 CDMA networks lack of support for multi-RAB. Multi-RAB refers to radio access bearers, basically multiple virtual connections across a single radio link. You might think of this like VLANs on an ethernet network.) you don't put the network and engineering expenses to support multiple RATs..

Actually, no. "HD" stands for "HD Voice" which is a better codec. Depending on the carrier, you may get HD voice on a 3G RAT and VoLTE RAT or just on a VoLTE RAT. Keep in mind that HD Voice uses more radio resource than the standard GSM codecs, so there's a trade-off involved here. LTE is more spectral efficient, so offering the higher quality, higher bit rate voice codec on VoLTE has less of an impact on the network than offering it on VoLTE + 3G. So depending on your carrier, they may or may not allow the HD codec on non-VoLTE radio connections. Either way, HD does not in any way shape or form constitute having a VoLTE connection, since it's radio access type independent.

My Pixel 2 XL does VoLTE on AT&T. "HD" might have different meanings in different cases but in this case the "HD" does mean VoLTE. Google specifically stated that in release notes for 8.1 on the Pixel 2 XL.
Also, back when I had a Galaxy S2 Skyrocket (AT&T's LTE variant of the Galaxy S2 and its first LTE phone) back in late 2011 it didn't do VoLTE but it did allow LTE data while a voice call was in progress.
