Galaxy J2 SM-J200F - How to Force LTE only ?

Hello,
I have a Samsung Galaxy J2 SM-J200F LTE, I usually just get 3G or H+ and I want to get an option to force LTE only.
I did the *#0011# it shows me the service menu :
1- I click the "Plus" button on top-right.
2- I click "Back".
3- Then input "Q".
4- Then "Back" again.
5- Finally input "0000".
I waited for 5 minutes, nothing happened. I repeated the process many times, but still I can't get to the options to choose "LTE only".
PS : I tried *#2263# too, but it shows nothing at all.
I even tried the app "4G LTE SWITCH" . But it says that my device is not compatible.
Please guys, help me.

Is it compatible with the carriers lte? Just because it says it has lte doesn't mean it will work on every carriers lte.
Also if all you are getting is 3g or lte then you may not be in lte coverage.

Yes, it is compatible with the carriers LTE bands, and there is a strong LTE coverage because I tested it in another phone having the same carrier too.
I just need a way to lock LTE only please

You dont want that. As LTE is a data signal only. If it was only LTE you would never get a phone call or text.
If it is not connection the LTE then my next guess would be that the antenna is not strong enough.
Remember not all devices are equal. Just because one works doesnt mean others will.

In fact I don't want to use the phone for calls, I just need to activate LTE only please.

Then you will have to build your own rom. Which still might not happen as the part that controls that is not open source. So it will take alot of work. And with that device you will most likely not be able to do anything about it as it is not modable and there is no device that even has the option for you to compare the code.
This is just something you may not be able to do

He wanted to enable LTE only mode. . .so there's a way you need to modify CSC features. .I tried this a year ago. . it's still working

Buy xiome Redmi 2 and above phones u can force lte stand by mode also higher version like Redmi 4 has dual sim supporting dual lte stand by mode.
Xiomi offers awesome features at lower costs...

Verizon M8 only connecting to 2G/GSM networks. No 3G/4G.

Hi All,
The issue with my Verizon M8 [the rare LRA (LTE for Rural America) subvariant] is that no matter what firmware version/RUU I use, I only get GSM connectivity on it. No WCDMA or LTE. I have checked the WCDMA bands in my country and that is not an issue. When I select WCDMA only option, I cannot get any signal. I have flashed the all the LRA (*.**.512.*) RUUs as well as all the Verizon (*.**.605.*) RUUs but no luck at all. If this issue might be related to PRL settings then please let me know if any of you have any idea. I have also checked the relevant WCDMA/LTE bands via CDMA tool and they are also enabled.
My M8 is currently S-off and has Super CID. I am using it outside the US on GSM network.
This has got me very frustrating and I need to find out if this is a software issue or a hardware issue. One more thing is that another guy here has exactly the same variant as mine. He bricked his radio by flashing the GSM firmware. I provided him my phone's relevant partition dumps and after flashing those onto his phone, his phone's radio became operational but now he has the same issue as mine. So I think that this issue might not be hardware related.
Any help on this will be greatly appreciated!!

Same problem

Anyone can provide any help on this??

do you know the actual bands/frequency the gsm network uses where you are? the prl is going to be pulled from your sim card. have you also tried a diff sim card?

Hello. Yes, I know the bands used by 2G, 3G and 4G in my country. And yes I have switched sim cards even from different networks. The PRL version shows as 00000 when i look at it from the settings. I have even tried to update the PRL from a prl file provided by a xda user in some other thread but still it shows as 00000. I have seen some threads and ppl had this problem with One S. Though some of them were able to correct it by flashing some stock and custom radios.

odd. i wonder if that lra model is sim locked like the sprint variant. is it also acknowledging you have a sim card inserted when you check in about phone? as in, does it display the sim #

Well, I thought too that it might be sim locked but then why it is working with 2G networks. There should be no signal at all then. Also these LRA variants are being sold by many online retailers including Amazon as sim unlocked phones. And yes it acknowledges when I insert or change a sim. Says "Preparing sim card" and then I get a signal (2G only). When I choose 3G only in network settings, the signal is gone immediately and I have to switch back to auto or 2G only to get the signal back.

So then list the specific band numbers for 2G, 3G, and LTE for your carrier. That is really what the previous response was asking.

This is strange, as the 3G band 2100 Mhz is really common (many countries use it for 3G, and most any recent US phone intended for foreign travel will support it), and should be supported by the device out-of-the-box. This tells me the problem is likely not RUU/firmware related.
You sure the APN is properly typed? And does your carrier use any different APN for 3G, LTE, etc.?

No it uses the same APN for all types and its configured correctly. I also thought the issue might rather be related to some NV values or PRL. If I set it to 3G only, it "Sees" the carrier as I can see a signal bar in network signal guru app, but the mobile is not able to connect to it.

so i am thinking that since this is a lra variant, a lot of bands may be disabled. have you seen anywhere else that someone got a lra variant to work outside the us? i know you said people were selling it as being unlocked, but maybe its not

Well the LRA variant is practically the Verizon one with everything same as the Verizon variant. There a lot of links on both Amazon and eBay in which its mentioned that its LRA variant and is factory unlocked and can be used anywhere in the world. And yes I came across various threads on XDA in which people had this same variant, working fine (3G atleast) but they wanted to upgrade to Android 6 MM as there is no official update available for this variant after Android 5 Lollipop. As for the relevant bands (2100MHz for 3G used in my country), they were already unlocked (checked via CDMA Tool and QXDM).

hmm this is quite the problem. if you can confirm you are using the same rom as the others, i would then think the issue is the radio being defective

I am using the stock LRA RUU (android 5.0.2). I have also tried the VZW RUUs from 4.4 to 6.0 but the same issue exists on them all. Even I have used GPE and Sense based custom roms but the same issue. I think that the issue might be related to some NV values or this phone might be network locked. Is there a way to check if the phone is network/sim locked? As I am getting the (2G) signals for all the networks in my country.

it being sim/network locked makes sense, because the phone was made for people who live in the middle of nowhere. there would also be a high probability that none of those people will ever travel outside the country. i do not know anything about the nv values and tweaking them, but i have looked at that thread a few times. lastly, if you have only picked up 2g regardless of sim or apn used, it could be defective radios

[Q] SM-G995FD on Freedom Mobile LTE

I have been trying to get my LTE working on my Samsung S8+ SM-G955FD with Freedom mobile. I have updated the CSC to XAC and GLW from the development forums and the phone will not connect to LTE at all. However flashing it to tmobiles CSC I was able to get LTE as it uses the same band 66. I initially got LTE by selecting the network operator "Home" once I lose connection from LTE to 4G it will not automatically reconnect back to LTE unless I select the network operator again. Any suggestions on fixing this?

Same issue with Reliance JIO (India) using VO LTE. Seems the phone does not support it either (the 6GB Ram Model)

up!
my 3g does work but lte not always!

I found this article around flashing csc, it seems like it's proven to work when they are the same model eg both g950w.
Keywords from the article since I'm too new a member to link directly. oneplus-5-other-unlocked-band-66-devices-may-be-incompatible-freedom

I would like to ask if you rooted your phone and changed the CSC as per instructions given in the Droidview website?
If you did, and the results were not satisfactory, then you would have tripped Knox, but gained little.
I am in the same situation, and am considering rooting the phone to try the method in Droidview.
Thanks.

I got s8+ from freedom and trust me I absolutely hate their reception. On a drive home or from I get interruptions of voice call for 5+min (highway drive) in some areas. Anywhere in US call reception is hit or miss. In Canada isnt always great other. Now for LTE well, it ok if you catch LTE signal. Allot of the times im on 4g. Speed are very slow. If im lucky I get LTE. So i don't know whether its the service or the phone but im not happy. I'll pay of this phone and move back to FIDO or on US network. Freedom is garbage to me. Im all over the city, country and north america - freedom isnt great for me. Fido was excellent but i didnt get any credit on the phones, in US fido rates are very high.

verify that you are in a location that gets a good signal and that it says you get 4g lte data. then goto connection settings>mobile networks and tap on network mode and choose the option in the screenshot. if it doesnt change do a factory reset. if that fails either get the stock rom from sammobile and flash it with odin or call samsung for a replacement. also verify that theres no upgrades or problems in your area by calling customer care and that your house doesnt limit your signal. my house sometimes limits mine due to it being metal all around. in that case putting your phone in a window fixes it. if you want to avoid that contact tmobile to get a signal booster for your house. update: in the *#2263# menu make sure to choose reset on both LTE and WCDMA in disable band.

Have you checked which bands your network supports against the bands your device supports?
You may have to open the network settings and modify the bands if possible.
Also which firmware are you running, you may need to flash the modem from the orange firmware?

HD Audio/ VoLTE

Is there a setting to enable VoLTE or some sort of HD phone call audio? I searched everywhere and i can't find something... The top speaker sounds like the other person is on speaker and talking from the bathroom...

Yes it's in the "Network and Internet" settings, under the "Mobile network" category.
Sorry if the labels are different on your phone. I'm using it in French.

It probably depends on the SIM card.
You could try asking your mobile network provider for a new SIM card. But I'm not sure at all that would fix this.

My network operator is Orange/Sosh(France) and there is no option for the VoLTE.

Guys the truth is... The phone is compatible with only a limited set of band frequencies..
THIS MEANS
Volte, 4G 5G etc will ONLY WORK IF your cell phone provider has the same frequencies that the phone requires.
If you cant enable Volte, It wont work cause your phone is NOT capable of working on your Cell Providers cell tower freqncies. Each company uses a different Frequency
Here in USA
ATT will ONLY work upto 3g. You will see an H on top the signal bar which indicates a Enhanced 3g speed also know as HSPA speed connection. I have tried 2 new sim cards. I have tried several APN's I have tried all updates and a reset. No 4G and no 5G on ATT. Unless someone can tell me something new, this phone will not FULLY work on ATT. Text works. Calls work. Internet is sort of hit and miss with decent signal but again rather slow.
T Mobile will ONLY work upto 4g. No Volte although it seems to have the capability of Volte it cant not work with Tmobile Volte because it seems the cell bands are not compatible. Text work. Internet works rather fast, Good solid signal however no 5G and no Volte due to incompatible cell bands.
I did research on this subject and found that the ATT cell bands for everything including 5G do seem to be compatible with the 7 pro but again, it does not FULLY work oddly
I also did research on Tmobile cell bands and the bands for 5G are not even close to being compatible. Volte is also non compatible. 4g is compatible and works..
If someone has a magick wand which can somehow make these features work on this fone in USA Id be willing to send a donation..
