[Q] 4G / LTE issues please help - Galaxy Note 3 Q&A, Help & Troubleshooting

I have a weird issue with LTE on my Note 3. When I go to settings, and set network mode to LTE/WCDMA/GSM, LTE sign next to signal strength in status bar appears for a second, and then disappears. And I can't use 4G network.
So I'm asking you, if anybody else have this issues? Is it problem with carrier or phone?
Everything except that works without problems.
Thank you.

What's the model of your Note 3 and carrier?
Doubt this could be the issue but have you checked with the APN for your network?

Not sure if this will help but you could give it a try.

Well, who knows, I changed APN settings and 2G/3G works, I'll see about 4G later because I can't catch the signal at home.
It's interesting that they have already sent me internet options by sms, and they are probably wrong.

It works now! I've just changed the APN settings and that's it. I can't believe that T-Mobile sends wrong settings.

The atrix is a 4g device correct? You have a data plan on file with at&t that is pointing to the 4g plan. You put a 4g data plan registered sim into a 3g device. I think this is your problem.
Enter your sim into a dumb phone. Go online and switch your data plan to medianet unlimited.
Then put sim in galaxy note and try again.
good luck

AFAIK 4G/3G/edge has nothing to do with the SIM or service. If he is getting EDGE, he should also get the other 3G on... if the device supports it. Worst to worst, call AT&T
post the apn you used

[Q] [Help] No 4g / LTE option LG G2 D802

Hi, I cant seem to switch my phone to 4g / LTE. I've tried the various *# hacks like LTE only, but i only get 'Not supported'. Anyone else experiencing this? I was using 4g and getting 4g speeds on my N5. The phone was previously locked and I unlocked it straight away after receiving it.
The software version is D80210g-234-30
Anyone?
im also interested on how to fix this. anyone?
Turns out it was just a problem with the sim / network I was using (Tesco (o2)). When I tried with another 4g sim the options for LTE showed just fine

It was a problem with my network provider, nothing to do with the phone. Try another 4g sim from another network and see if you get 4g / LTE
I contacted LG today about the 4G issues that many experience and I thought I should share the official response:
Many Thanks for your email regarding your LG G2, I am sorry to hear you are experiencing problems in receiving 4G.
Can I just ask whom your network provider is? All main UK network providers bar a couple are receiving 4G via our handset, there are only a few 4G networks at the moment who are yet to approve the software on the G2. Please note it is not a limitation of the handset but is network dependent
The above will also explain why some other people in the area are getting it, their networks are almost certainly among those whom have approved the software on the G2 handset.
I look forward to your earliest response with the network provider, once received we should be able to clarify this for you.

Hi, I have recently upgraded my phone to a sim free LG G2 also, and in doing so spoke to Tesco Mobile about receiving a new 4G sim to match my upgraded tariff.
This has all been put in place but I still have no ability to select LTE in the preferred network section. New APN settings were sent out by Tesco but this didnt make any additional setting options available, has anyone got any more info on this issue or advice?

You probably also have an non-EUR software version installed on your G2. Where did you buy it from?
If the above stands, the solution is to flash the EUR software version, although I haven't as I do not really need 4G for the time being. 3G is completely fine.

The handset was purchased from Expansys in the UK and the software is version D80220b-EUR-XX.
So I would not have expected that this issue would come up, it seems to be a unique blend of Tesco(UK) carrier settings and the handset software.
I won't be flashing any new ROM as a solution for a problem which sits with the carrier. Though I am keen to hear if any other users have found an alternative work around.

You already have a EUR software version, so you do not have to flash.
There is a problem with some carriers in the UK not approving the G2 4G software as I have stated above.
Had the same problem.
Changed the SIM for a new one (still labelled 3G 128k) and 4G is fine now (stock JB D802 SIM free).
My previous SIM was almost from the turn of the century (cut to fit microSIM)
I'm having the same problem, no LTE option, here's a solution:
Enter Android test menu by dialing *#*#4636#*#*
Go to Phone Information ... Set preffered network type ... f.e. to LTE/GSM/WCDMA ... if LTE is available, my phone switches to LTE ( showing 4G ) immediately without restarting.
This is what I did

Verizon Note 4 on t-mobile network

I've been using it on tmo since yesterday. Solid signal, very stable so far. I ran speedtest this morning and got 56 up\26 down. The speed is crazy fast.
To get the Note 4 working on Verizon:
1. Change the APN setting.
http://support.t-mobile.com/docs/DOC-2090
2. Change the network mode to Global in Mobile networks (same place where you set the APN)
3. Change the voice mail number.
-Open the Phone app, click on the 3 dot Menu button, go to Settings, select Call, select Voice Mail Setting, and change the number from *86 to 123.
-I use Google Voice, so I just switch mine to Google Voice.
4. If touch tone DTMF is not working for you, try to turn of noise reduction or change the DTMF from Short to Long.
5. To get rid of the annoying SIM message in the notification. Tap, hold the message and select App Info then force close it. Do this every time you reboot the phone.
Hi, noob question here, I am also using tmo network on a verizon note 4 but I can't seem to go online... I was told to changed the Network mode to GSM but still nothing. it also says the Signal strength is -67 dBm 23 asu. Any help would be great thanks!

You need to add T-Mobiles APN google it!
Good to know. I'll be taking this bad boy to Asia next month. Sounds like it'd be a no problem sticking a new sim card as long as I get the APN down ?

how to remove Verizon bloatware
I'm using the Verizon note 4 with the T Mobile SIM card and it works well, it connects to 4G LTE, but I cannot use mobile hotspot because its integrated with Verizon's services. All the APN settings are fine but it says mobile number not found.
Does anyone know how to remove all of the Verizon bloatware? Things such as the Playstore and settings even have Verizon bloat. Data Usage tool also does not work either.
Also to note, whenever i reboot the phone a permanent notification apoears saying something like, "Sim card is not Verizon," which can only be removed if you force close the activation agent. Its annoying that Verizon left its mark throughout parts of the phone.
Is it possible to make this a Regular galaxy note 4?
(Another weird thing is that the settings menu cannot be switched to carousel mode which the T-Mobile version can do.)
hi i tried my t-mobile sim in my verizon note 4 but lte is not working it only works on hspa
so what apn settings did u use can u pls tell me the apn settings for lte.

I think T-Mobile sims for lte should use
fast.t-mobile.com
also make sure you do have LTE in your area.

To get rid of that notification, press and hold it until the App Info window appears. Hit that window then you'll go to the Activation Agent app settings. Push "Force Close" and it will disappear.
Nice and easy but the only problem is that you have to do this every time you restart your phone.

Does your phone have a clean esn from verizon or is it considered a "bad esn" (lost phone)? Just curious if they work outside verizon with bad esn.

It depends if your market uses LTE band 4. Probably though.
Also, it looks like (once root is achieved) you'll be able to add more LTE bands.
Do we lose frequencies when we use a verizon phone on tmobile? Doesn't seem to have band 12.

Shouldn't be an issue since AT&T and T-Mobile primarily use band 4. The other bands are for additional bandwidth if there is congestion and T-Mobile uses band 12 in limited markets.

tried that now same thing H, and no lte
had my kid take the sim out of his 6 plus on att,,boom lte fired rite up,maybe a 2 yr old sim needs replacing ??
I'm seeing the same issue. After boot, the phone is stuck on HSPA. Toggle airplane mode, then the 6p connects to LTE.
I know T-Mo folks have similar issues. For T-Mo, I read about toggling the "Advanced LTE" setting and rebooting resolves the issue.
I would like to find a better solution than toggle airplane mode with ATT.
I called att. I had the same issue last year with my moto x pure. They had refresh their system and reenter the imei number and change my device. I rebooted and it works now. You can chat online if you want. The apn settings should auto plug in when you boot the phone with whatever carriers sim card.
Thanks for this thread. I was noticing it stuck on H all day. Brand new sim, just got it yesterday for this phone from AT&T...
Just glad to know about airplane mode toggle trick, it works great.
Tried resetting APN's, but didn't help.
I'll call AT&T soon and see if they can fix it permanently on their side ?
Sent from my Nexus 6P using Tapatalk
For those on AT&T, who *never* sees LTE, even after airplane mode toggle, will need to contact the carrier and have them provision the line for LTE. The easiest way to do this is to put the SIM into an AT&T-branded LTE phone. This way, the system will "see" that you're using an LTE phone and by the time you call, the agent can simply make the needed provision. You can put the SIM back into the 6p thereafter and LTE will stick, even if AT&T's system does not recognize the IMEI.
*However*, if the airplane mode toggle works to connect to LTE or you have ever seen LTE on your 6p in the past, this is then likely NOT a carrier problem. See this thread. What @slaydog and many others are experiencing is caused by a ROM/radio bug. It is intermittent. There is currently no fix for it and a bug report has been filed with Google. We are hoping that the next patch release fixes the problem.
I ordered my nano SIM from AT&T before I received my 6P. The rep had to look up the SKU of the SIM that works for the 6P so that the correct one was shipped. I had LTE service the moment the phone powered up. I would have AT&T send you a new replacement for the two year old SIM, and make sure you let them kmow that it is for a Huawei Nexus 6P.

You should give it a try if you didnt.(does not void warranty)

Yes,data works but calls don't
I'm going to suggest a longshot here. It seems that you've gotten some good suggestions so far, so I want to throw this idea out there.
Have you "provisioned" your phone lately & updated the PRL? Meaning, have you told the phone to connect to your cellular carrier, then the carrier then tells your phone what services you are paying for & are supposed to have & what cellular towers you can use? Doing just this usually fixes all sorts of problems.
Go to Settings (the little gear icon), then More (in the Wireless & Networks). Cellular Networks, Carrier Settings. Tap on Update device config. Let it talk to the network. Tap on OK. After that, Update the PRL. Let it do it's thing. Tap on OK.
No reboot is necessary. It should be making calls, receiving calls & data should all be working.
Also, I keep the Preferred network type to global, although my carrier is CDMA & I'm in the US.

Really don't know either then. You said that you tried to change your preferred Network from LTE to 2g/3g but you can't? Are you always connected to LTE then? As far as i know you can't call on LTE.
my phone is also can not call and receive calls,text and 4G are still useful.It just stay in 4g and can not change to 2/3g.Hope someone can help us.
