LTE not working for me. (90% SOLVED)

Update: 4/13
I was just able to figure it out and for the most part. The basic problem is that my network mode was stuck on GSM/WCDMA. Here is the solution:
1. go to settings/more.../mobile networks/network operators.
2. Once you click network operators, it should start searching automatically. If nothing comes up, then hit "search networks". FYI, sometimes, it decides to act wonky, so you'll have to exit out and come back in to get it to work. Eventually, it'll show you carriers in the area. Being an AT&T customer in Philadelphia. I saw three results. The first two were AT&T. The last one was T-Mobile. I don't think there is a difference in the AT&T options, but I just clicked the first one.
3. Once that's finished. Go back to the "mobile networks" menu and click on "network mode" and change your preferred network mode to LTE/GSM/CDMA.
4. The last step is change your APN. In the "mobile networks" menu, click on Access Point Names. Click on ATT LTE pta. Scroll to the bottom and click on APN Type. Change that to default,admin,fota,mms,supl,hip. Then hit okay. Hit File and Save. Then just select the circle next to ATT LTE pta. To be honest, just selecting ATT LTE PTA might be all that's necessary. You might not have to edit it.
Now, here's the catch. All of this stuff resets (with the exception of the edited APN) when you restart your phone. But it does work everytime.[/COLOR]
So, I just got the skyrocket (AT&T in Philadelphia) and have the 03-24 nightly on it. But for some reason, I can't get LTE to turn on. I've played with the different APN's. I've flashed the at&t radio on Chopstick's webpage, but no dice. I'm only getting H+.
I even called AT&T to make sure my data plan was LTE provisioned.
The only thing I can think of is that the ROM currently cannot change preferred network mode and mine is stuck on GSM/WCDMA preferred?
Please help.

OT but where in Philly? I'm a NE transplant from SW.
Additionally, I'm on the Rogers rom and have LTE so def not AT&T.

What modem and APN are you using?

Re: LTE not working for me.
Use the latest one, I think the one on the chopsticks web page is old.

Which radio or baseband version is it?

How old is your SIM card?
When I got my Skyrocket, all network modes except LTE worked.
It ended up being an older version of a sim card that didn't support LTE.
Swapped out for a new one...no issues since.

I doubt that's the problem. I actually flashed back to Stock this morning and LTE worked great. I had speeds around 35mbps. However when I restored the backup of the CM10.1 rom, same issue. Only gettings H+ and speeds around 2mpbs.
THIS IS SO FRUSTRATING!!!! I don't get it. Am I really the only person with CM10.1 not getting LTE? It doesn't make any sense.

Would you kindly answer these questions so that I may ascertain whatever is it I'm doing wrong?
1. Are you using an AT&T Skyrocket? or is one from Rogers/others?
2. Are you using the official CM10.1? Which build?
3. What your baseband version?
4. What APN are you using?
5. In the mobile network settings/preferred network mode dialog in settings, what option is checked?
The only thing I can think of is that the preferred network mode for me is stuck on GSM/WCDMA preferred?

Would you kindly just check your preferred network mode for me? In case you don't know, it's on settings/more/mobilenetworks/networkmode.
And just to confirm, you are getting LTE with the 4G Signal notifier, correct?

Is that CM 10.1? Looks like AOKP. Also did you so something special to get the 2nd option? On my ROM, it won't allow me to change it from GSM/WCDMA

Try doing the following just to see if you can pick up LTE at all. If you do whats below you will not get any voice calls until you change it back since voice does not use LTE. In you dialer, enter *#*#4636#*#*, select phone information, scroll down and you should see a drop down menu, change from the default GSM/LTE to LTE only. To get voice back change it back to GSM/LTE

New Nexus 5 - network problem (a complicated one)

Hi
need your help, I have tried everything..
I can not connect to 3G
I tried to flash image factory/set correct APN setting with the operator/switch radios/replacing new SIM.
didn't helped my!
When I connect to 2G everything works for me, calls and online.
When I switch to 3G, I have no service, it writes me Unavailable operator.
It get stuck on the "Search" when I try to search manually.
When I try to go back to 2G, it is still stuck on "searching.." and I have no reception! Only reboot fixes it and I can go back to work with 2G.
It is important to note that when I take out the SIM I can find operator on 3G.
How can I fix the problem or even understand what it comes from?
I have Nexus tool kit, maybe I can sent you Catlog \ bugreprot?!
Thank You in Advance

What about, when you are in LTE ? Will you get 3G ? You should get either 3G or Edge (came to know that your country don't have LTE yet).

I don't have LTE in my country yet, and my operator only have 2G (no EDGE)

If you choose LTE on your phone, it supports all lower versions (i.e 3G / Edge) ! So you must get Edge (2G) !
LTE option doesn't force only LTE !

I know, if I choose LTE I get the same problem, no service..

This. The Nexus 5 very well may not support the 3G frequencies your network uses.
Sent from my iPhone 5s using Tapatalk

I certainly know that this is not the problem, Nexus 5 is supported in my country
Should not be a problem with the 3G frequencies of both models 820 \ 821.

If that's the case, I'd recommend contacting your carrier.

I do believe that Verizon is using Advance Calling as a way to use WiFi for calls as long as your phone supports Advance calling. Of course it still has to be enabled and it still uses minutes if you don't have unlimited talk time.

It is when you're not on WiFi. If I remember correctly Verizon has the calls going over WiFi when connected even if you're in LTE coverage.

If that's correct, I should be able to make calls over WiFi if I have super spotty 3G coverage? I'm out in BFE Kansas and despite being on WiFi and having advanced calling enabled, I can barely get a call through. I was pretty sure Verizon doesn't use WiFi at all for calling.

Yeah I don't think volte uses wifi. I wish they'd add it so we could make calls when we're outside the us

No LTE on T-Mobile with S7

Since purchasing this phone about a month ago, I haven't had LTE. I checked my SIM in my wife's iPhone 6s and it pulled LTE. My t-mobile rep said they know about the issue and quickly set me up for a warranty exchange. Anyone else have this issue? If it's a known issue, why isn't anyone else talking about it?
Can you guys confirm that the S7 has a designated stock LTE icon? Mine always says 4G and Ookla says my download/upload are 7.5 and 12.2 respectfully.
EDIT: latest firmware, no case on device, in Lemoore, CA., no known outages

Everything is good here.. I get "4G LTE" in the top bar...
You said that you put your wife's SIM card in your S7 and you got LTE?

Vise versa actually. My SIM pulled LTE on her iPhone. Her SIM in my S7 only got 4G, just like my SIM does in it.

My s7 also doesn't say LTE, only 4g. Is it suppose to say LTE? I'm in a major metropolitan area and haven't seen LTE. I got 100Mbps though from home.

I haven't seen it but it sounds like it could be an incorrect APN setting. But I would have thought they would have you check that.

We checked the APN and even made another with T-mobiles settings manually inputted. Still nothing. The new phone comes Thursday. I will see if it's the phone, the service, or there really isn't an issue and where I live just sucks.

My Tmobile S7 never says LTE either. It always says 4G. I downloaded the LTE Discovery app from the Play Store and it clearly states that I am connected to the LTE network. It shows the signal strength, channel and tower I'm connected to. Hope that helps.

You guys are joking right? You're using Good Lock which uses the stock Google System UI icons. 4G = LTE
This is a pic of my homescreen, Icon shows 4G but I'm on LTE (Band 4).

No one was joking, and to comment with guns-a-blazing with the goal of offending someone isn't what this place is about. My area is suffering a congestion issue, so my LTE is still spotty. But at least I know that there is a designated LTE icon.

I do not know closest cross streets but putting just Lemoore, CA 93245 in search on the Sensorly website 4G is in surrounding areas but solid coverage is only for 3G. Check on the website and put in your cross streets. Looking on the Root Metrics coverage map shows 4G LTE.

Isn't 4g and lte the same thing?

Not really. LTE doesn't fully satisfy the requirements of a 4th generation GPRS. It is getting there, though. @42freelancer, I hope you don't do a warranty exchange over a UI bug. Do some speed tests and real use (Youtube, etc) to see what sort of service you're getting. The stock Samsung firmware for the S6 says 4G, not LTE...
