I had the news that my carrier was enabling 3G so after looking for it "the normal way" and failing, I used he 4636 code, BUT when changing bands I enabled the 3 I had as options one by one and nothing (USA Band, Cellular, PCS) now I dont have access to neither my 2G GSM network because my carrier is in gsm 900MHz. And it doesnt have that option.
What can I do?
I have a factory unlocked Moto G4 Plus xt1644. RetUSA.
Please help me!
Thanks in advance.

Hey Guys,
I have just bought a olleh branded S7 edge(SM-G935K/Korean version) from eBay. I'm very happy with it so far, but it seems that 4g is not working, only 3g. I looked trough the internet, but couldn't find anything. What I do found out is that it supports all the correct 4g frequencies. It also looks that some of the settings are blocked or simply not there. For example, when I go into Setting - Mobile networks, I only see a greyed out Data roaming, normal Access Point Names and greyed out Status bar indicator. There is no Network mode and no Network operators. Maybe this is because of the olleh branding?
Thanks!
Hi,
I have got the same issue. but I have 4G working. I would like to know how to get data roaming working too. Any expert can point it out how to fix the data roaming would be greatly appreciated.
P.S. I am on Australia Vodafone network. I do get LTE and LTE+. I can share my setting if you need any info.
Does anyone know how to solve the problem with the LTE option in Celluar Data, because I cant't choose LTE just 2G, 3G and 3G/2G? No LTE/3G/2G option.
It's a model Blackberry Keyone BB100-2, Android version 7.1.1, Build Number is AAN358.
If anyone has an official software please send it to me or post a link.
Try dialing *#*#46368676#*#*
Not sure what network you're on, but this thread on Crackberry talks about a way to activate LTE and advanced calling on Verizon. The solution is to have the SIM card activated in a Verizon (not just "Verizon-compatible") phone, then transfer it to the Blackberry. I'm not sure if the same process works for other networks.
Download "4G Switcher" in PlayStore.
It's a saviour.

I don't know where you live, but BB100-2 is not a US variant, so LTE bands might not be available to you.
Now is OK. Problem was with firmware on BB. After update from BB service, LTE working fine and you can choose Mobile Data (LTE, 3G, 2G).
Firmware
Where or how did you get that firmware update, please?
Hi!
I get new unlocked H910, but I am not able to connect to LTE bands 1,3,7 and 20 in Europe. I use Czech SIM. The phone finds the network, but does not connect. I found out, that these bands are listed in the H910 specs. like roaming bands. Is it possible to enable it somehow to work for me?
Thanks

If you are rooted my answer is similar the my answer here only now the settings you want are in the band.selection area.

Unfortunatelly, I am not rooted.
I find out, that root could disable the FM radio - is it truth? That was one of reasons why to buy V20 (together with infraport).
Thanks again
Hi, Im newbie here, and eng is foreign language for me. Sorry for mistakes.
I have an LG V20 H910. Unlocked. No root. And he works only with 2g (edge). 3g, 4g isn't working. But in specs, he have bands what I need.
https://www.frequencycheck.com/models/vVVRj/lg-h910-v20-lte-a-h915
My operator bands:
2g: 900MHz, 1800MHz
3g: 2100MHz
4g: Band3-1800MHz, Band7-2600MHz
I've tryed https://forum.xda-developers.com/v20/help/t-mobile-v20-band-12-solved-t3508910
But in my case *#546368#*918# menu is much different, there is no options like "choose bands" or smth.
Any possibilities do turn on at least 3g band?
P.S. Once, when I'm switching sims, the phone dind't find network much time. Then I've installed V10 hidden menu https://play.google.com/store/apps/details?id=you.love.v10.hidden.settings&hl=ru and simple change option "Mobile network" (GSM/WCDMA/LTE and CGS/WCDMA). I have tap on this two times on final chose GSM/WCDMA/LTE. On the top appeared 4g icon. The speed was about 4 mb/s. But it was one time, when reboot the phone all dissapears and I cant repeat my experience again.
try adding APN manually.

I did it. + I show this phone to my carrier experts. They sad, that they can't help, couse ATT somehow locked bands. Is it possible?
P.S. Once again: phone is unlocked and work in 2g.
I think if this was on V20 it may helps me https://forum.xda-developers.com/lg-g3/general/request-3g-2g-lte-d850-t3300908 . But it is G3.

It might be locked in the ROM. If you are up to rooting, you can put a custom ROM on it and there is a high chance it would work.
Same situation here. Tried all custom roms i could find with the same result: kernel crash at boot menu
READ THE [UPDATE] DOWN BELOW
Many Note3 Korean Variant users also reported this case
https://forum.xda-developers.com/showthread.php?t=2484602&page=115
The problem is that, I can't connect to LTE without losing my Network Radio Service Connection. I can connect to E/G/3G/H/H+ and still have network service, so I can still make calls and text messages, but when I turn on my Mobile Data, when it tries to connect to LTE, suddenly my service gets diconnected and I can't make phone calls nor messages though I could still use the data. I've already tried 3 LTE-Capable SIMS but the issue still happens.
What I had in mind is that it might be because it is Carrier Locked since it is a Korean Variant, but the problem still persists even after flasing other custom roms (this includes Note 7 Port ROMS, LineageOS, Stock-Based ROMS).
I love my Note 3, I will do anything to keep it alive, but still this one problem keeps bugging me...
Why can't I use both LTE data connection and radio service connection simultaneously?
Is anyone out there knowledge and willing enough to help us Note 3 KV users with this issue? :crying:
[UPDATE]
I get it now, when a phone is using LTE it means its not connected to any Mobile Network Service, instead it is connected to Data Network Service, yet it should receive Phone calls and Messages but it means that the phone will disconnect to LTE and switch to GSM/WCDMA (E/G/H/3G/H+) to be able to recieve the incoming call or message. I've tried that with my friends' phones, The first phone is connected to Data and is using LTE and the other phone is trying to call the first phone. The moment I call the first phone, I noticed that the LTE icon dropped to H and then recieve the call, It only happened because the option selected on the "Network Mode" (under Settings/More Networks/Mobile Networks-->Network Mode) is [LTE/WCDMA/GSM auto connect] so that's how it works
But that doesn't happen to my phone, after turning off the Mobile Data (I was connected to LTE btw) my phone doesn't automatically connect to GSM nor WCDMA network, it just stay on LTE mode and I have to manually select the GSM/WCDMA option in order to get Network Service.
So my final question is Why doesn't my Note 3 automatically switches Network Mode?
Note 3
Model Number: N900L
Status: Rooted with Custom Note 7 Port ROM
Condition: Good, No History of Repair
Current Network: SMART Prepaid
Does it work on genuine non custom stock firmware ??

No it doesn't, the problem is already there even before I rooted my device. Flashing stock lollipop rom on odin didn't help either

Please start to read about LTE technology and its frenquency bands.
Then find answers to these questions :
1- My SM-N900L is locked to use which frequency bands ?
2- Wich bands are in use in my actual location (country) ?
3- Is it possible to unlock more frequency bands for my N900L ?
i can provide more help if things remains not clear enough.
Good luck :good:

I tried searching the supported LTE bands of N900L but I can't find any sites that tell exactly what the N900L actually supports though I found out on this forum
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
1) A / P / T / V models are made exclusively for the US operator market and for no other people, as their indexes hint (A-AT & T / P-SPRINT / T-MOBILE / V-VERIZON). In Europe, mainly international versions are used - in the case of NOTE 3 - exclusively N9005, in Canada - its own carrier versions.
2) The models N900S / N900K / N900L are identical in the set of supported frequencies. If you rewind the topic on page 9, you will see screenshots of one of these models, which show the frequencies you are using, in one of the screens you will see the treasured frequency of LTE b7. I think that users of this topic can be trusted with respect to information in the topic, but no one has elected you the right to believe solely on the site www.frequencycheck.com.

I did try checking my phone on www.frequencycheck.com, N900L is not on the list..
https://www.frequencycheck.com/models/AZzWA/samsung-sm-n900s-galaxy-note-3-lte-a
N900S though shows that it supports Bands 3, 5, and 17.
I also look it up on wikipedia on where the SMART network (my current network) falls on the list of LTE frequency bands, and it shows that it is on Band 05 alongside with South Korean Networks LGU+ and SKT. The supported LTE bands on my country are Band 1, 3, 5, 7, 28 and 41
https://www.frequencycheck.com/countries/philippines
I searched for how to unlock all LTE frequency bands on N900L or Korean Variants or Note 3 but the only option that shows up is by accessing the Service Menu on Stock ROM and manually changing the values, which still didn't work for me.
According to my search, N900L is locked to :
LTE protocol : B1 (2100) and B5 (850)
LTE-A protocol : B3 (1800) and B7 (2600)
Now try to find the specific frequency band used by your carrier (he can't use all of the six available bands in Philippines), and activate it.
Wich stock firmware do you use when trying to access Service Mode ? It must be the LGU+ one.
And what code did you dial for the same purpose ?

When you said activate, you mean select the band to be used by the phone right?
- Yes, I used the LGU+ Lollipop Stock ROM
- I typed in the dialpad, *#0011# and changed the network preference to LTE ONLY.

I mean activate only the LTE's frquency band used by your carrier.
Check your PM.

I've already done that, but the problem with radio service network is still present, I can't make or receive any phones calls nor messages.
