found in the testing screen the preferred network was set to cdma only, not cdma + lte/evdo auto like my other phone but it wont stay to the other, don't know if that is it or not

I'm having the same problem.

I wasn't able to connect to LTE until I changed my network mode under Settings > Mobile Data to either Automatic or LTE/CDMA. It was defaulted to CDMA Only.

Hmmm..I just exchanged my silver for a black one and also cannot get 4g. My wife has one and hers gets it just fine. My old one did as well. I have checked all the setting suggested above and still nada. Seems this one is going back as well.

I'm on my 2nd HTC one and it operates the same as my 1st one.. In the dock of my car it connects to 4G just fine..with in a few seconds of handling the phone it drops to 3G..It works fine in great signal areas but on the out skirts of an LTE tower it just won't hold 4G..

Update prl and update profile

Im in the same boat. Seems like 4g is HORRIBLE with this phone. Had the Note 2 and wife has GS4 both pick up 4g no problem, but the One picks up 4g for couple seconds then drops off completely. Yes, I tested this in the same areas.
really bummed out cuz I got the phone used so i can't return it. Love the phone, but its useless if i can't get 4g because Sprint's 3g is so slow its unusable.

Well I just exchanged my black and went back to silver and still the same issue. I am starting to think the guy that set up my phone on my account jacked something up. I have been all through the service provisioning matching it to my friend that has one....and only found one difference. Seems my phone is only picking up CDMA-EVDO Rev-a instead of CDMA - eHRPD. When I change the prefered network from LTE/CDMA it will try to connect to eHRPD but then switches back to EVDO and no 4G. So I will try to call sprint and have them inspect my account as I have not seen a way in the service programming to force eHRPD. It would be nice to have the others that are having this issue check the Mobile network type as well and see what they are running.

Try not touching the phone and see that it holds 4G until you touch it...I know its pretty useless to not be able to touch your phone but this has been my experience.

In my experience, not touching the phone does not seem to fix the problem. I do notice a small signal loss if I have the left side of the phone against the palm of my hand. The real issue here seems to be related to the phone having some sort of broken threshold from when to switch to 3g to 4g and how much better the 3g signal has to be in order to decide to switch off of 4g to 3g.
I noticed that the LTE Scan Time is set way higher than what the EVO LTE is set to with latest firmware (300 on the HTC One vs 5 on the EVO LTE). I have not had much time to test changing this to see if it makes a real difference or not though. You can check what your LTE scan time is set to in ##3282#. You will need to get your MSL to change it if you want to do that (there is a method to get your MSL without rooting here on XDA).
Another thing you can try to see if it is indeed a reception problem or a problem with the phone not switching between 3G and 4G smartly is to set the phone to LTE / CDMA(1xRTT) only. You can do this in *#*#4636#*#* under the phone information submenu. Tap where it says "CDMA + LTE/EvDo auto" and change it to "LTE, CDMA" or even "LTE only".

Issue resolved for me! After 6 phone exchanges I was able to uncover what was causing the phone to not get on eHRPD which is Sprints upgraded software on the towers. I called sprint support and made them verify my UICC ID under about/phone identity, this also is the same as number as the SIM id. They did not match what was on my account. I went back to Best Buy and they called activation's and they sent a profile update with the correct SIM and UICC ID and it solved the issue. No more 104 data issues and I can get 4G now. WOO HOO!
I do want to say that Sprint really went to bat for me to get this resolved. I have to say thanks to the San Diego Sprint rep who kept in touch with me through out all of this.....Thank you man!!!

I had the exact same problem. My phone will not connect to 4G LTE. I have a few questions. How do I know the UICC ID, SIM? Where do I find them under my account?
Thanks a lot

You have to call sprint customer care to have them verify what you have on your phone. I recommend calling from some other phone when you call though. Just explain that you are having issues with your data and you heard that sometimes the UUIC ID/SIM ID are incorrect. They might come back and tell you, "well thats for international only" but in fact the SIM ID is used for LTE from what I found out. Just insist (nicely) that you just want to try it.
On the phone you can see your SIM ID under settings/about/Phone Identity.
One way to see if this fixes the issue is look under settings/about/Network and look under Mobil Network Type. If it is always running in EvDo rev A. then you have the issue if the towers in your area have Network Vision updated towers.
Hope this helps...PM me if you want more information. I can also get you tower data in your area if you would like.

slayer69, Thank you so much for your quick response. My phone runs with EHRPD when it showed 3G, not rev. A. However, my phone had the same issue, not connecting to 4G/LTE. From time to time, it will show 4G signal on the bar. However, when I tried to use it, it will switch back to 3G. I will call sprint to verify if tI have the sim card issue.

I talked with Sprint. It seemed that my SIM/UICC code is matched with the system. So my problem is still not resolved. I used an app to check the signal information, which showed that I have -70dB LTE signal. However, I just can't connect to LTE.
It seems that it is not only me. Check this link

Thanks to all in this thread. I had the same problem while in Oakland. My wife has an S2 on sprint and she had a strong 4g connection and mine was stuck on 3g. Now if this is a hardware issue that this phone has what if anything can we do. Can we exchange for a different device

I got a new Sim from Verizon and it still doesn't have voice or data....is there a setting I need to toggle? Settings for the radio? Do I need to activate the phone in the Verizon website?

Use a friend's phone, and call Verizon to activate your phone. They'll look up the IMEI, and other pertinent information, and you should be up and running in a matter of minutes.
But yeah, *228 has been a no-no for quite a while now. It could cook your SIM, and damage the internals. As a matter of interest, why did you go that route, instead of just calling VZW in the first place?

Help on getting phone working on straight talk.

Long story short. I was using a Verizon branded note 2 on straight talk when my contract ended with verizon. I grew tired of the phone and purchased the blu vivo xl from amazon a few days ago. Now I know that my sim in my Verizon wouldn't work on the blu phone because it's not compatible.
So I went on chat to switch my Verizon sim to an att sim from the same byop package (which also came with a tmobile sim) They said that it could take anywhere from an hour to 2 days to convert over, and that I'll know when it happens because my note 2 will stop working. Sure enough it stopped and a bit later my blu phone started getting a signal and 4G icon.
However, it was in and out all night and since then I haven't got it back. Frustrated, I then switched it to the tmobile sim. I get the 4G lte icon and arrows move up and down. My signal goes from 2/4 bars to 3/4 bars. Now I'm thinking good that's more than what att was able to do. Wrong. Well not completely.
I can send a text and my wife will get it. Not really slow but not normal. She'll reply and I can receive it. But I can't access the internet, and I can't call or receive calls. Went on chat they gave me apns to input and still nothing. I still get 4G icon and I still get service.
I really like this phone but this transition has been really draining.
Thanks you for your help.

I have no idea, I had a really smooth transition activating it onto metro. Maybe you just have spotty coverage with straight talk in your area? I'll try looking for more info

Correct. The phone is loaded with apns that matched what they gave me. The straight talk for att and tmobile.
So as an update, I bought a tmobile sim, (not straight talk this time) the phone received texts from tmobile for this and that. I have good signal as indicated from the bars. 4G lte icon is on (but no data due to not having a tmobile account, but the sim is allowed 30 texts and 30 minutes of talk time until I get one)
The problem that is persisting is that I cannot make a call. I'll dial any number between my wife's, friends even my own and it just gets stuck on dialing. No operator or anything just blank. It's flashing "dialing..." but it won't actually go and do anything.
I contacted blu, and they gave me the same apns that I used and assured me that it should work on straight talk. But yet still nothing. I contacted blu again after I got the tmobile sim. I'm awaiting an answer on that before I proclaim the phone a dud and exchange with amazon.com.

StraightTalk is owned and operated by Tracfone. I went through more blood pressure pills dealing with them than almost any other corporation. Best bet? Switch to almost any other carrier. I use Airvoice, but there are a BUNCH of others out there with no contract, pay-as-you-go programs. Truly, there are better deals out there than StraightTalk/Tracfone.

You are having issues (I think) because different phones available through Straight Talk work on different networks. They ask for your zip code and then show you phones from different networks that will work in your area. If you use a SIM card you are AT&T or T-Mobile. Sprint and Verizon use CDMA. Check coverage maps. This will explain why your coverage is spotty now. There is a list floating around out there that shows which networks use what phones and so on for Straight Talk. Once you put the SIM card in the phone, it picks up whatever network is available in your area. If it's a network that doesn't have great coverage where you are, service is diminished.

OnePlus 3T On Verizon

So I was bored and wanted to play around and try to get this to work. So far I have been successful to get data text and mms working on 3G. Now I have noticed that when I boot the phone that it connects to LTE with a strong signal then it reconnects back to 3G its almost like its possible but something it blocking it. Has anyone had success getting further?

UPDATE: I have gotten FULL LTE on Verizon working. Currently trying to figure out a way to allow CDMA as well for calls

Ya good luck I had same issue as you . Talk text 3g working good. Or LTE only working .Never could figure out how to get them both going

Yea I know after hours of messing around lol and two sim cards wasn't satisfying enough I like the phone enough to jump off big red to try T-Mobile. I honestly like this phone better then my Pixel XL

I ditched my Verizon unlimited data plan for cricket unlimited and have no regrets. Best choice I ever made

It won't work it's one or the other. You are wasting your time

The city I live In has Verizon's xlte network and if you upgrade to advanced Calling then voice calls and messages all use 4g LTE data instead of CDMA, so I would only need LTE data to work, I was able to get the 1+1 to get Verizon's signal but after 5 mins they noticed and intentionally blocked me off their Network a message popped up on the 1+1 saying I had been blocked

You have to add VoLTE on the phone AND with the carrier. you did both of these options, and t hen were blocked? Did you ever call and ask "why?"?

Just curious how you have "LTE" activated on the phone. I turned on "only LTE", but I get absolutely nothing. I am only interested in LTE on t he phone, I do not need to make voice calls of SMS

Force LTE provisioning
I know that people had the same issue on the ZTE axon 7 but we're able to force LTE provisioning by going into the dialer and dialing *#*#4636#*#*. This brings up a hidden test menu and under phone information there is a switch for LTE provisioning. It takes a few tries but eventually sticks on the axon. Can someone try this on the one plus phones to see if it works?

I know this has been rehashed many times, but I thought I'd share a my experiences of how to make the 3T usable on Verizon. Main reason I have the 3T is dual SIM and OEM bootloader unlock. Fantastic device. Switched from Verizon to AT&T just for the phone. The problem is my work uses Verizon. I refuse to carry two phones. So what I've done to solve this is bought the GravityBox app, which has a feature that allows, (among many things!) you to add a custom quick setting shortcut for Network Mode. It lets you decide which SIM the setting applies to, as well as any network modes to cycle through when pressing the shortcut. I of course pick the Verizon SIM. And only select two network modes: 1 CDMA only and 2 LTE only. CDMA only allows calls,text and 2G to work perfectly. When a sending or receiving a MMS on Verizon SIM, or needing to use Verizon LTE, I toggle to Verizon LTE only. This does kick AT&T offline for some reason, but beings that I rarely need to use Verizon data, it's not that big of deal.

No Voice over LTE

So, I finally talked my wife out of her LG phone and got her an identical VZW Nexus 6. So we now have identical phones. I have unlocked the bootloaders, installed TWRP, and both are running CarbonROM weeklies.
For some reason, my phone has voice over LTE, and everything works just fine. Hers drops LTE every time she makes or receives a call. I've been searching xda and google for 3 days, checking and double checking that all settings match on the phones, flashing different radios, etc. And the setting for "Enhanced LTE Service" doesn't even show up in her settings.
If I put the preferred network to "LTE", (same as mine) she can't even make a call. It acts like it's going to dial, then drops signal completely.
Any ideas?

I would check and make sure Verizon has it provisioned to use volte

How would I go about checking to see if it is provisioned for VoLTE? It is on straight talk service now. When I contacted StraightTalk support, they told me that their service doesn't support it. And they didn't have an answer after I told them that mine does it just fine. LoL

Actually, they said maybe the phone needs an update...

Clarify the following. Are both N6es on Verizon, both on Straight Talk, or one on Verizon and the other on Straight Talk?
The last time I looked into it, Straight Talk didn't support VOLTE. Has that changed?

They are both on Straight Talk, using verizon sim cards. The tech support told me the same thing. That they didn't support VOLTE. And had no explanation when I told her that my phone was using it just fine.

It doesn't function on the AT&T side of Straight Talk and AT&T definitely has VOLTE. Thus, the fact you have it is an anomaly, and your other device not having it isn't an issue with the device or its firmware. In other words, consider yourself lucky.

Well, I'm not one to give up very easily. So, after some thinking, I may have come up with an idea.
Both phones were purchased from Swappa. My phone was listed as a Verizon phone, while the other was listed as an unlocked phone (no idea what carrier it was previously used with).
I'm thinking that adm1jtg may be correct, My phone would have been provisioned for VolTE, and the other phone may have never been on their network to get provisioned...
So, I think I will switch her to Verizon prepaid which doesn't cost much more and see if that fixes it. Maybe after a month switch back to straight talk. I will update this post afterwards, and let you guys know if that does the trick.
Maybe overthinking it a bit. After I switch her to verizon prepaid, and get her phone all set up and see that VoLTE is working, I'll pop my straight talk sim in it and let you guys know the results...

Soo... I had some time to think about it, and decided to just swap sim cards between the two phones. Turns out, it isn't her phone at all. With my straight talk sim, her phone got Enhanced 4G/Lte.
With her straight talk sim, my phone did not. Put my straight talk sim back in my phone, and Enhanced 4G/Lte came back.
Turns out that Strephon Alkhalikoi is correct.
I wonder how many BYOP sim kits I would have to go through to find another anomaly... LoL
