LTE/CDMA in ro.radio.networkmode screws up phone.

Hi, guys I recently ran into an issue with the build prop modification in regards to network selection. If I enable the network selection as pointed out in one of the other threads and select LTE /CDMA my phone will lock on LTE however no phone calls can be made out or recieved. I had to reflash to 10k then reroot and then change the build prop to CA/TLS and finally hardreset via stock recovery. Anybody else have this issue?
UPDATE... looks like as long as i dont try to make a call the option to switch it back to auto is still there. One a call is attempted and fails the option to set to auto disappears.

Most carriers Phone calls and Texts dont go through LTE...... If your setting it to LTE only thats why.

I understand but after it's been on LTE for a while it doesn't give you the option to switch back.

Depending on what rom your using under mobile networks there is network selections with
LTE/WCDMA/GSM
GSM Only
WCDMA Only
and LTE only

Right, thats what normally the options are however after about 5 min after selecting LTE/CDMA the only options that appear were.
LTE/CDMA

How are you changing it? Changing it via Build.Prop? Then there is your problem, JUST change it using the setting under mobile networks..

Stop changing it to lte/cdma and you're phone will no longer mess up. Leave it on gsm/wcdma/lte auto. You're phone will switch when the appropriate network is available!!!

Simple fix. Just select airplane mode for a few and then toggle it off and you'll see your network options come back once data roaming turns off and your carrier logo appears. I typically run lte/CDMA to get consistent lte speed bit when a callsade I have the same issue as you. But I just gave your the fix so your good

Thanks a lot captain obvious, the point of the thread wasn't to "not switch it" dude, it's finding a work around and make everybody aware of what happens.

Help 4g

Hello friend, i bought a new m9 and when i activate data mobile i have only 3g , i tryed factory reset, to setup my network,
I rooted my phone, installed custom room.. still no change.. anyone can know why ?

Well maybe you dont have great 4g signal in your area? Or change apn.

As stated already , the signal could be weak in your area. Type in the dialer key pad ##3282# and you can also look to make sure all the bands are enabled on your device. I don't see why they wouldn't be though. A handful of users have stated bad connectivity with the M9, but that's on the sprint network I have been reading about.

at ##3282# it say only OK.. nothing about enable bands and i tryed sim of my friend (vodafone 4g) he have m8 and 4g working... on my m9 doesnt..

I have same problem with my M9+. In Manchester Area UK
I had perfect 4G with my old M8 but with new phone only 3G!!
Let me know if you get any answers. HTC and Vodafone couldnt help me either.

Check access point names, make sure only one is listed and selected.
Go to networks and search for network, click automatic.
Open the connectivity selection and make sure that the scalable option is chosen (2g/3g/4g)
Are you using one Base with the wrong firmware? Make sure they match up.
Find a friend on the same network or shared network and see if they have 4g in your location.
Test the sim in another phone.
Call network to check for issues in your area and or if there is an error against your account, may need a new sim if that one is old.
Test in major parts of the city center next time you're shopping..
Perform a speed test to see what speed you're actually getting, hspa is up to 20mb, 4g AFAIK is around 60mb, I've had 48 before. Anything over 20 could be considered 4g, you will very very rarely see a 3G tariff go over 19mb, which is the most I've ever seen.
Good luck.

I have the same issue with the M9. Couldn't find an answer for this problem. Even tried opening lte bands as listed here but no luck.
The thing is that I used to get LTE where I am now, went on long holiday and can't get it to work again so no idea what's up.

I tried my sim with my wife's iphone and i got 4g without any problem. It's not a sim issue. Whatever the problem is, it's with the device (hardware, software, settings). I remember it also took me a few weeks after getting the M9 to get a 4g signal, but then one day it just appeared so there's that to add to the mystery.

Reset your network settings mate, set to manual then back to automatic.
Make sure you actually catch the network on manual first before manual. You will find it, it's just a case of going through the motions.
Also click menu, reset to defaults in access point names.

1. How do you "reset network settings"?
2. set to manual - you mean in 'Network operators' menu select 'Search networks', select my network, then go back and selecting 'Select automatically'?
3. What do you mean "just a case of going through the motions"?
4. Should I reset APN at the last step or at the beginning?
I'm trying to understand your steps as clearly as i possible can because this no 4g issue took a lot of time and effort from me and it still doesn't work. Any help is very much appreciated.

I am trying to help you.
There are no steps it's just a case of trying everything to do with the network. If what you say is true and you've literally just had this issue occur out of the blue then it has to be a difference on the handset, especially seeing as you have tested the sim in another phone and it works.
Reset to default is with apn, doesn't matter when you do this just reset them, make sure it's checked and cycle mobile data on and off.
Clarify that your device is set to 2g/3g/4g within network mode (I believe it's called)
And I was referring to setting network selection to manual within mobile network settings, then choosing your network, then researching and selecting automatic.
The path is: settings / mobile data / network operators / search networks, wait for yours and select it, cycle mobile data (turn off then back on) if that doesn't work, switch back to automatic.
Reboot your phone after making changes, perform the full shut down method instead of the restart or power off methods, it's power and volume up AFAIK, hold for 10+ seconds, might be 15.
Going through the motions refers to checking anything and everything which influences the network, one of these setting will get it working..
Might be seen as overkill but a factory reset (if it's not been tried already) good luck.

I know you are trying to help me, and I very much appreciate it. Truly am.
I tried doing all the steps you listed, but no luck. Even tried at some point to force lte only in 4636 screen but that resulted in no signal at all. Trying to manually select a network in that setting only gives me the other 2 networks that work in the area but not vodafone which is what I use.
As a complete overkill I RUU earlier to the new 2.11.617 firmware without signing into my google account or restoring anything, and still no lte. What I did saw however, in the select network screen, was that next to my network, it said 2g/3g and next to the other 2 networks here it said 2g/3g/4g. Obliviously I can't select them as it's a vodafone simcard.
I added here SS from LTE discovery app while i was on 'lte only' mode. You can see signal is there but it cannot connect.
Any wild ideas or suggestions? I'm opened to try almost anything

Just out of interest, have you tried a different sim card? I know you said that your sim worked in another phone but I'd still be tempted to contact voda to get a new sim and to see if everything is set up on a network level, you may have to tell via that the issue is persistent in different phones or they may make you pay for it.
Also, might be something to do with the association between your phone and your sim. I once had a sim that blocked my missus, she could call me but I couldn't call her, no active diverts of any kind, I could call anyone and they could call me, got a new sim and it was sorted. Very strange, but anomalies like this do occur.
Have you got any mods or are you at stock at the moment? I know you said ruu. Oh and lol click thanks BTW.

Well the thing is that my wife's sim card in my phone only gets 3g. On her iPhone it's 4g. My sim card in my wife's iPhone gets 4g. On my phone only 3g so it seems like a very specific problem with my device.
Shortly after ruu I installed viper 3.5 without any mods..
Can it be that my device is somehow blocked by the network towers or something of that nature?
Maybe a hidden setting somewhere that blocking the phone's 4g capabilities? This is getting ridiculous..

No worries fella
If you've already tried another sim and it's still not happening, the firmware matches the rom, your sim works in other phones with 4g. Then I'm really not sure mate..
Give Lee droid a whirl that's what I'm using at the moment.. A simple but great rom..
I'm pretty much out of ideas now, if all of the above has been checked then it's something that I'm not aware of.. Sorry mate..
for the record it is a weird one, something should have got it working by now..

I can't return the device as it was bought in the states and I live in Europe at the moment.
I think I will try to change my sim card for a new one just in case, and will change back to stock 2.11.617 for a couple of days to see if that can make any difference.
Will post an update if i will have one.

Disable the dam Volte Notification?

I keep getting this dam "Your device is VOLTE Capable" it pops up like every 10-20 minutes. It is very annoying. I have tried to disable it, but nothing works just keeps popping up. How the heck do you disable this notification?? I have already enabled that feature so I'm not sure why I keep getting the notification. I even tried disabling the service but it is greyed out.

I agree! 1+ Enable it!

if you dont have it enabled it wont come on. for me i have no use for it. only thing it bugs me is when im on a call im going to 3g . while its turn on it stays on lte

There has to be a way to turn off the notification. I've got to figure it out. It's really annoying you can't at the moment. I also posted in the official Oneplus 3 forums too, so far no reply...

There is a way to turn it off. Go to settings>cellular networks>sim you want to change. Turn off the "Enhanced 4G LTE mode"
Notification will not turn on any more.
Sent from my ONEPLUS A3000 using Tapatalk

Yes I know that. With it on it shouldn't tell you or bug you every 10 minutes to tell you, hey volte is working. Every other phone that is volte does not have a notification telling you every 10 minutes that it is working.

Sorry, my bad. I misread the question. I thought you wanted it off all together

Did you find a solution for this issue? Is very annoying

I've just been swiping it away. No clue why it keeps reappearing.

That's actually a problem I wouldn't mind having. What network are you with and how did you enable VoLTE in the first place?

I'm with Rogers in Canada and I have VoLTE on my iPhone 6s and my s7 edge... For some reason out here they only make VoLTE available for their devices. I had an unlocked note 5 from Bell which was the same model. Changes the csc to match and VoLTE still didn't work.

They might just not have the phones correct information in their DB as a VoLTE capable device. I couldn't get LTE at all through at&t until I had them change my imei to an old phone I had laying around. I'm wondering if you guys are having similar issues. At&t rep told me the op3 imei come up as a basic data phone and not an LTE device.
Anyone else you know up there with VoLTE working?
Edit: I see you tried the swap already using the note 5.

I'm running Resurrection Remix rom and I just have to long press the notification and then there's an option to turn off the notification. Do it and it won't come back. Also I wasn't even sure that VolTe was working but I found out that if you open your dialer and choose the screen that you dial numbers on, On the top left of the page it will say "VolTe". That means it's working. Hope this was help.

AT&T Unlocked Note 5 on T-Mobile

Hello is anyone using the AT&T Note 5 unlocked on T-Mobile? I'm having issues with calls on this device and wanted to know if anyone else was having problems. When I went to T-Mobile they told me they had upgraded their towers and because my phone wasn't the T-Mobile variant it could no longer access the call service.
Any help is appreciated

Unable to receive calls whatsoever.
Spoke to Tmo and they said they've done some upgrades on the network and they're seeing this issue a lot more now with non-tmobile phones.
I'm now looking around to see if there are any radio/kernel/rom flashes that can help solve the issue.

Hey thanks for the videos, but I have no idea what they're actually changing in the 2nd one and I dont have the app/shortcut used in the first video.

yo need an app called shortcut master lite

I have idea which code you added to the app. Is it possible for you enable touch pointer in Developer settings to show where you're actually touching the screen? You move too fast to follow in the video.
And which ones you added? Or did you follow any guide online?

Guess I'll have to look for another phone.

Got same issue.. U guys found any work-around??

Yup I got the same issue in NYC area too, TMO is not helping at all

Yes *2263# and unlock all your bands. TMO likes to use dedicated bands for RX and TX

For me setting the bands to automatic was the issue, if I set it to GSM and LTE it works fine. *#2263# > [1] Band Selection > [7] LTE/GSM Auto [*]

It works thank you!

Thank you so much. It works! Spent weeks working with TMO support and their solution was to ask me to buy a new TMO phone.

By any chance, are you guys allowed to dial 911?

Yes

I'm also thinking of buying an AT&T Note 5 (they're easier to find than the T-mobile one).
Are you able to get Band 12?
What about Volte? I saw somewhere (I think it was some T-mobile support page but don't know if current) that without Volte you can't have Data and phone call at the same time.
Any advantage to the AT&T version over the T-mobile?
Thanks

I know it is, but try to select it, and see if it does anything. On my phone, the network type doesn't change no matter what I select

Can't be because of the sim because I usually do this when I use the phone as a hot-spot to keep the phone in 4g. But I haven't used this option in a while, about the same time I upgraded to ob21... I just wanted to make sure it's not because of it. Thank you

Hello. Can someone with ob21 on op3 please confirm if he/she/it can switch the network from GSM to LTE only, or any other combination? Cheers
I can't. And I'm trying to find out why.

Sounds good, doesn't work :laugh:
Seriously now, tried but no luck

What I know, there must exist support on Phone (ok), SIM (ok), LTE (ok) and telecom provider (nok). Phone must be on "white list". I have the same problem.

I had success eith this om SIM1 only when I first got my OP3T, but now it doesnt work any more It still switches to 3g for calls whereas before it did not, but dropped the calls.
I need LTE only often where 3g and 4g are both bad and the phone keeps rolling over between the two. I just need net at that time.
Anyone succeeded in ysimg some app for this?
