No more LTE for me since JB update

The phone is set to auto (LTE/GSM/WCDMA), all I get now is HSPA+.
Anyone else lost the access to LTE network?
Im with Bell Mobility btw.

Yeah same for me with Rogers

I'm on AT&T but had the same issue. When in Network Mode, change it to LTE only then turn the radio on and off, after that I was able to get LTE working again. Once I changed it back to LTE/GSM/WCDMA It still kept LTE on as usual.

Did you check from settings or just status bar icon? If it's showing 4G in status bar, it's LTE.

With Bell there is no 4G, it either indicates H+ or LTE.
I still get LTE (where available) on Jelly Bean.

I'm on ATT JB update and not showing 4G icon, but am getting LTE speeds, 20 down/10 up basically.
EDIT oh I have toggle mod in place which prob accounts for no 4G in status bar.
EDIT 2 Well now I have 4G toggle, so just ignore me. Having a Monday moment guess lol.

The problem is in my area. I just came back from Montréal and got the LTE notification as soon as I crossed the bridge.
I also made a speed test:
DL: 51063
UL: 21029
The usual Bell LTE speed.

No 4G LTE on AT&T GSG3
I have AOKP JB 42 on my AT&T SGS3. After installing the Rom I am just seeing 4G icon instead of 4G LTE. I don't see any change in the speed though. Is this a known thing? or should I be changing some setting to get back the 4G LTE Icon?

I've lost 4G on my N7105

Cut a long story short, I got my new N7105 yesterday and rooted it straight away,
I then made a BIG mistake and installed a N7100 rom onto it which messed it all up and lost all reception on my phone.
couldnt make calls ect.
someone on here sent me a link to download the stock N7105 rom and it worked. i can now make calls ect.
BUT... since this has happened, i have not been on 4G once.
i've tried everything, been inside and outside, trying to get 4G.
before this all happened, i had 4G everytime i turned my wireless off.
I'm based in london UK, so there is really good 4G here.
anyone know the reason why i have lost my 4G?
do i need to download something to get it back?

Go to Settings > (Under Wireless and Networks) More Settings > Mobile Networks
and check what network mode it is set at.
It should be like the following:

yeah thats exactly how it is.
like i said, i've got reception, i get 3G, but just dont ever pick up 4G.
its as if i've done something wrong when installing the wrong rom and its messed up my 4G.

I presume your on EE?
You might want to check what network operator your phone is set to (it's right underneath Network mode)

Yes Mr.Larner is on EE T.Mobile

Also try switching between network modes (so switch to WCDMA and switch back to LTE) this used to happen to me until EE built more transmitter masts.

that is what even i am suspecting , had him call his service provider to check with that they ran couple of tests and said everything is fine
are you on same carrier if yes share your Settings ?

Yes I am on the same carrier. My settings are:
I just checked the EE forums and this is what the APN should look like:
Name = Internet
APN = everywhere (case sensitive)
Proxy = Leave Blank
Port = Leave Blank
Username = eesecure
Password = secure
Server = Leave Blank
MMSC = Leave Blank
MMS proxy = Leave Blank
MMS port = Leave Blank
MCC = 234
MNC = 30
Authentication type = PAP
APN type = default
APN protocol = IPv4
Bearer = Unspecified

Finally after a lot of juggling around flashed WanamLite rom with custom kernel now Mr Larner has his smooth 4g back.

N910V No signal in Argentina

Hello everyone,
I bought a Unlocked Note 4 from Verizon in USA. In Argentina I don't have signal. We use GSM so it should work right. I know this device has not root access. I just want to make some calls or messages.
It doesn't let me search network manually. It throws an error "error searching networks"
Android Version: 4.4.4
Network Mode: Global/GSM
Somebody could help me on this.
Thanks in advance.

I am in Europe past month, leaving to us in few days and was using my note4 in GSM mode all the time and switching between carriers on a prepaid sim. I would do factory reset or maybe get a new sim.
My prepaid sim allows roaming on all carriers.

I tried with many SIMs, I flashed the device three times and I still having. So maybe there is a another issue. Please someone can help me. How is the Micro SIM should I use?

Which carrier are you using this on? Verizon has always used CDMA for 3G, not GSM. The Verizon Note 4 (SM-N910V) does seem to have limited GSM support, but it might not work on every GSM carrier.
This website seems to be pretty accurate: http://www.willmyphonework.net/

Acording to that page my phone should work perfectly
with 2G, 3G, 4G LTE.
I'm using:
Brand: Samsung
Model: SM-N910V
Country:Argentina
Carrier:Claro Argentina
I don't know what is the problem.:crying:

You may need to add new APN settings before it will work.
On mine, the option to add a new APN is disabled, but I'm actually using mine on Verizon with a Verizon SIM card, so I'd have no reason to edit the APN settings manually. Are you able to edit yours?

I already set the APN and nothing happens. I'm not sure APN could be the problem. Should be something else.

I have an Oneplus One with the same APN and works perfectly. That's why I think the APNs are not causing the problems of signal. I still having no signal. I cant make neither a call nor send a message.

Hmm sorry bro not sure what is going on.. last thing I could suggest if you have some money to spare try any other sim card from different provider or ask a friend to swap it for a minute or two,anything to test that it's not your carrier somehow not wanting to work with VZW N4.

Hey I read something couple days ago and forgot to get back at you.. I read somewhere if you block activation agent it should work some people on T-Mobile USA had the same issue. Use debloater to block activation agent on boot. They said this could be because the note could never been activated on Verizon even for 30 seconds and this is why it might be happening.
So block activation agent,and setup wizard so it's blocked on EACH BOOT.
Let me know

Have u tried inserting dummy verizon sim?

I do not have any dummy sim from Verison.

Verizon and the OnePlus 3?

Howdy!
So I've read that the OnePlus 3 is not compatible with Verizon, but if you look at the bands it's only missing Band 13. Wouldn't the others still work?
Thanks!

I will report on July 1 when my opo arrives.
Sent from my Shield Tablet using XDA-Developers mobile app

Verizon's primary band is Band 13 (700c) according to this website below.
http://www.phonearena.com/news/Chea...on-T-Mobile-and-Sprint-use-in-the-USA_id77933

Maybe the band will become editable by a rom. But who knows

700mhz B13 is not really a "primary" band it just happens to be what Verizon first launched.
I highly doubt that we will see 700 B13 on the OPO3. Vzw is rumored to be rolling out B2 1900 but I'm not sure if it's officially launched in any markets. There is also the fact that vzw uses CDMA BC0 800mhz, which if I read the specs correctly is supported by the OPO3.
All this being said I doubt the OPO3 will work fully supported by vzw.
Of course there are some brilliant people in the xda community who can probably shed some more light on the subject.

It will work with Verizon 3G I saw in a review video. Not LTE tho.
Sent from my VK815 using XDA-Developers mobile app

It has LTE bands 2 and 4, thus if VZW has LTE bands 2/4 in your area then it should work. I'm having issues getting the LG-H830 working, but it doesn't have CDMA. It connects to band4 in my area but no icon, since I believe it needs CDMA for auth.
I haven't tried this yet but you may be able to add band 13
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

Do you think a call to VZW customer care would allow one to know what bands are in an area? You'd obviously need to get an upper level service tech on the line...but could they tell you?

I would say waste of time based on my experiencettalking to them. Better off using apps to figure it out. If you don't have Verizon, just visit the store nearest to you and install LTE Discovery on a display phone.

Why would it not work on LTE? It supports bands 2 and 4. If your area is VZW band 13 only then yeah it won't get 4g signal.
Sent from my rooted and BL unlocked LG-H830 using XDA-Developers app

Surprisingly Skizzy034 is correct, 3G (eHRPD) works. I had to enable data roaming first, but I can make/receive calls, sms, mms, and cellular data.
I've also been able to force a connection to LTE. However, when I do this sms, mms and calls don't work (data only).
Basically there is no transition between 3G and 4G.
I've messed around with the build.prop to see if I can get the phone to treat 4G as the preferred connection and only use 3G for sms, mms, and calls but I havent made any progress.
I'm confident that with help from the dev community we can actually get this thing working fairly well on vzw.

Did you pull the VZW apn xml file from a VZW phone and swap out yours? I can send if needed. I would like to buy OP3 and I use Verizon, so I'm definitely interested in what you're trying to accomplish.
What do you mean by forcing LTE? Setting RAT to LTE only?
Sent from my rooted and BL unlocked LG-H830 using XDA-Developers app

The APNs appear to have auto configured (attached a screenshot).
When I say "forced into LTE" I have manually changed the RAT to LTE only. This only appears to only work consistently on CM based roms. I did get OOS to lock onto LTE once but I've not been able to do it again.

If you set RAT to auto do you get both CDMA and LTE? On stock vzw phones, it seems multi APNs are used (VZWIMS and vzinternet)
Were you able to unlock band 13 (http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059)? What LTE band are you connected to? LTE Discovery app from play store can provide that info if you need.
Have you tried:
telephony.lteOnCdmaDevice=1
ro.telephony.default_network=10 ro.cdma.home.operator.alpha=Verizon ro.cdma.home.operator.numeric=311480 gsm.sim.operator.alpha=Verizon gsm.sim.operator.numeric=311480 gsm.operator.alpha=Verizon gsm.operator.numeric=311480
Sent from my rooted and BL unlocked LG-H830 using XDA-Developers app

I have not tried any of those things.
I'm hesitant to bother with attempting to unlock band 13. I spent a lot of time working on that on my opo1 and didn't work.
But I'm willing to give it a shot. I'm on vacation and don't have access to a PC so gonna be a few days. But I can apply the build.prop edits in the next few hours.

I made the build.prop edits you suggested jhasty01. Unfortunately they had no effect.
I'm going to work on unlocking Band13. Because I'm a market that is almost 100% covered by Band4 it is difficult to tell if Band13 is actually working. Perhaps I could disable Band4 but I'm hesitant.
I'm really hoping some of the devs who have worked with RIL can land a hand.
The larger obstacle is getting the RAT to conditionally handoff.

Any updates? Hoping so, would like to buy!

Some possibly helpful information from https://forums.oneplus.net/threads/trying-to-get-op3-working-on-verizon.452925/
Not sure if this is the case for Verizon but it is a known issue for ATT customers have LTE connection issues.
CAUSE: The IMEI for both sim slots are listed to only be set to receive 2G (H), hspa network. So if you contacted your service provider and registered your sim card with either of OP3 IMEI's, then you will not get LTE.
WORKAROUND: get your service provider to put your IMEI back to a previous phone that had LTE service.
NOTE: I had the same issue because I had to get a new Sim card because I went from a microsim to a nanosim. You access your phone information, by dialing *#*#4636#*#*. It will show your "Network type" only as hspa instead of LTE. There is no way to force it to LTE on your end, you have to contact your service provider.

Make sure you enabled roaming!

*Update*
Using qpst+qdxm I attempted to set radio/modem to prefer vzw bands and possibly enable B13. I was able to make the changes but the NVRAM resets to default values after power cycling. There is an NVRAM patch for the OnePlusOne which I flashed but it did not play well with the OPO3 and resulted is reboots and black screens. I tested all this on one of the recent CM builds.
I modified the build.prop to force "LTE only" (ro.telephony.default_network=11). Since I use Google Voice/Hangouts for calls and text I can make due.
I have reached out to @Mentor.37 who has been helping patch CDMA phones with GSM caoabilities to work better on GSM networks. He understands what the goal is and said mid-late August he should be able to help. @jhasty1 I only get 3G/eHRPD when roaming is enabled. No matter what ROM the RAT will not automatically transition from 3G44G. I have tried almost every ROM and modified what I thought might help with in the build.prop.
@jhasty1, as for the thread you mentioned (https://forums.oneplus.net/threads/trying-to-get-op3-working-on-verizon.452925/) there is a lot of conflicting information. There are many who say the OPO3 will not work on VZW. Well it is working, I'm using it to write this. I also had the OPO1 working on VZW using B4 LTE data.
As it stands, unless forced into "LTE only" the default RAT is 3G/eHRPD.
If we get some dev support I believe the phone could work very well.

I've been able to attach to LTE on bands 2,4 and 5. Now as far as I know vzw has not began using band 5. I think what's happening is I'm roaming on att for some reason.

Pixel doesn't connect to data when roaming.

I am on T-Mobile and when I roam, my phone will connect to the network for phone calls and SMS, but will not connect to the data services. I have it turned on for data roaming in the settings. My wife's 6P is also on T-Mobile and connects to data just fine. Any ideas?

There is an option to reset the cellular network in settings. I was roaming in South Korea for the last 3 weeks with the pixel xl and didnt have any issues. Roaming is set off by default.

Any update
Any update to this? I just discovered that I'm experiencing the same thing.

I have the same issue. I can put my SIM back in my Nexus 5x, roaming works. In my Pixel, it can call and text, but no data.

Does it work temporarely when you turn on and off the flightmode?

i have the same problem but it sometimes works temporarily when I manually switch to another network while roaming

Mine did the same, went into mobile network settings, network operators, search networks and then choose automatically. Also make sure data roaming is on.
The phone then started working for roaming, in one country I had to do this twice before it picked it up

Change the APN Protocol (not for roaming protocol) to IPV4/V6.
You could also go into the testing menu (dial *#*#4636#*#* - phone information) to global auto but I think that setting gets reset every now and then.

Was working on my first trip overseas two mons ago. Same location as before but now i
I am am also on T-Mobile. On my first trip to Nicaragua two months ago my pixel work fine. Now my phone will connect to the network for phone calls and SMS, but will not connect to the data services. I have it turned on for data roaming in the settings. My wife's S5 is also on T-Mobile and connects to data just fine. T-MOBILE reset me several times. I will get a message then from Claro or Movistar saying no data because your data roming is off. No matter if I have it switched to on or off after resting I will get the message everytime.

I was having this same issue in Thailand and not Japan. Changing to ipv4/v6 didn't help but explicitly changing to 3g preferred instead of LTE preferred fixed it for me

Posting this to add the list of things that may work..
I have a Pixel 2 and was having this same issue with a Twilio sim card (runs on T-Mobile) while in Australia, New Zealand, and later in Ireland (home network is USA). I had tried all kinds of random APN tweeks mentioned in this thread (https://forum.xda-developers.com/tmobile-lg-g3/help/international-data-roaming-to-t2823789) with no success. I had also contacted google and they sent me a whole new pixel 2 but that made no difference. After much googling heres what I found:
Edit the APN settings and click the APN Type. Add "default" to the beginning of that list. Try and save, it will tell you that you can't set the type to default, that's fine. Press the home button and re-navigate to the mobile settings and default should be successfully saved in the APN type. That alone resolved the data connection issues for me but I was only getting H internet rather than LTE. I then also changed the MVNO setting to `SPN` and suddenly got LTE connectivity.
