Just wondering, will the LTE versions support voice + data at the same time? Couldnt find the answer anywhere. Anyone got info ?

If you are on verizon and connected to 4g lte then you can simultaneously use data and voice on ANY 4g device.
same goes for AT&T, works with 3G as well
GSM (3G, HSDPA/HSDPA+/H LTE/) can do voice and data
CDMA has been able to do voice and data for a while now due to SVDO (As long as the device supports it)

So using the secret menu, I was trying different methods to see what signal strengths I was getting at my place, same spot. Interesting enough, the signal strength bars are different when using CDMA auto prl (4-bars) and EvDo only (2-bars) mode, even though I still see the 3g icon. Also, it seems the 1x radio is always on in every mode except EvDo only, plus I tried calling using all 5 modes.
Thus far, (1-yes, 0-no) I can make a call in mode:
CDMA auto PRL - 1
CDMA only - 1
EvDo only - 0
CDMA + LTE/EvDo - 1
LTE only - 1
so my question is, why can't I (and is anyone able to) make calls over EvDo only mode? When I place one, it hangs for a sec, and ends automatically saying "Call was lost". I was hoping to get better call quality (even if I can't have 4g speed), cuz right now calls sometimes sound muffled (but clear enough to understand), compared to when I had my nexus one on t-mo. (I tried eHRPD and EvDo-rev.a modes to no avail)
PS I know (atleast I read somewhere) that the T-Bolt cannot support calls over LTE itself, or VoLTE as it's called (unless if that's changed or I am wrong.)
Any thoughts? your experiences? I just want to get ppl's thoughts on this.
So... I guess no answers then?
Well, EvDO-only would not permit any voice calls because you've told the radio to only operate with a data signal. EvDO, or "Evolution-Data Optimized", is the 3G data component of CDMA wireless networks, so without a preferred network mode that includes CDMA you won't have any voice service.
when i had my phone on evdo only (stupidly thinking it was 1x) i couldn't make or receive any calls
evdo handles data, 1x handles calls/sms

Right. CDMA = 1x data and voice EVDO = data only. If you force the phone into a data only mode, voice will not function.
Hello,
I have a Samsung galaxy s3 international rooted and stock Samsung 4.1.2.
My question is I got the cheapest package of t mobile which is 500mb of high speed data (unlimited 2g)and unlimited calls and texts. I wanted to know is there a way I can manually just use 2g when I want to versus 4g?
Do I have to switch network mode? There is auto, gsm and wcdma. Which one should I be on?
P. S. I can use 2g only if I switch to gsm but then I can't receive phone calls. I can call though. Same situation with auto.
Please help!

GSM only will force 2G. And if you can make calls Id assume it should be possible to receive them.
I have never used google voice before. I know that Sprint has a google voice integration. Is there a way to use the google voice integration to avoid being disconected from lte when a call comes in?
If not possible is there a setting in the dialer code that would enable lte to stay on and avoid calls temporarily?
If anyone is interested I found the way to have uninterupted data while on lte. I used an app in the play store named "lte settings". I use it to set the radio to lte only. The only drawback is that no calls or sms or able to get through while it is in this mode. it is easy to switch back and forth. I use it if I am downloading or using tether and do not want a call to disconnect me.

This application looks pointless. You can just as easily access this menu by going into your phone and pressing *#*#4636#*#*. This allows you to change the phone to LTE Only, CDMA + LTE/EVDO, etc. It also lets you force your phone to search on a given frequency, such as Cellular, PCS, or Secondary 800 MHz.
Just for the record, the Sprint version will NEVER be able to do SVLTE or SVDO. Don't ask. It simply cannot be done unless you use VoIP software. The hardware on the Sprint version cannot do more than one type of connection, as in either it has LTE, CDMA or EVDO.

No secret codes work for verizon stock so that app is far from pointless...
Those of us in a new aws area would want to change to lte only to test it out or if we needed it data only.

How do you change to LTE Only, CDMA + LTE/EVDO in the ##4636 settings? Also how do you force it to search on a certain frequency?
Can this phone run on Sprint network and do VOICE & DATA Simultaneously? like a Note

According to the specification sheet, my Le Max 2 (Model X820) has all the bands required for Verizon. I am always interested in finding out whether it can be used on Verizon network, and if so, how. I have done quite a bit of experiments and would like to share my findings.
First thing first, and I am sure most of us know it - you cannot activate a Verizon SIM using this phone. It must be an activated Verizon SIM that you pop into this phone.
I am using an Xfinity Mobile SIM, which uses Verizon. It is not a Verizon prepaid or post-paid SIM. I do not think it makes any difference in my experiment though.
I can get one of the two working conditions: (1) 3G voice + 3G data, or (2) 4G data but no voice. In case (1), the phone is connected to Verizon’s EvDo network. Voice works fine. Data also works, but it is only 3G. In a phone call, data is disconnected, which is what an EvDo network does. In case (2), LTE data works, but Voice is out of service. I did try VoLTE but to no luck (The same SIM works fine with VoLTE in a Nexus 6P).
To me, only case (1) is a workable solution. When one would like to think in case (2), we can supplement Verizon’s LTE data with voice from another SIM. It does not work. When LTE data is set to use Verizon, the other SIM does not work at all. Some people may be fine with Hangouts or a VoIP solution though.
For a dual-SIM set up, it goes like this: SIM 1 – Verizon, for voice/SMS, SIM 2 – ATT or T-Mobile, for data. The drawback is that when you are in a call, data is disconnected.
But even for such a set up to work, there is some work to be done. Based on my limited knowledge of how Verizon’s CDMA network works, it seems that for voice to work, some provisioning must be done (information such as MDN, PRL, etc.). I find that this provisioning is only doable in a Chinese stock ROM. Once that is done, use TWRP to make a copy of the EFS partition. That is my savior. With such a “provisioned” EFS, it is possible to use Verizon in custom ROMs such as RR or lineage. If this EFS partition is overwritten, then the phone will not work with Verizon in case (1).
I know in the past, people have used software such as CDMA workshop, or Qualcomm’s programming software to set parameters for CDMA network. I do not know if it will work for this phone or not. But that is clearly beyond my skill level.
How do you get 3g voice and 3g data work?
Heyyo, tbh I made a build of LineageOS 15.1 with some kanged verizon files from Sagit (Xiaomi Mi6) but of course I can't test it as I am in Canada... if you're willing to try it out and report your testing it would be appreciated.

I cannot test it since I am not on lineage. Op mentioned he can get 3g voice and 3g data. I would wonder how to get those since I only get 4g data.

Sorry for a late response.
For 3G voice and data to work, I chose to force 3G in settings. I used the RR ROM. Settings --> More --> Cellular networks --> Preferred network type: Choose 3G instead of LTE.
You can also use the dialer, enter *#*#4626#*#*, then Phone information. You can choose network mode there too.
