Hello modders,
I am considering buying the Xperia Z because I really like the device and software.
However after my first hands-on experience, I have discovered that the c6603 model, sold by our carrier (T-Mobile CZ), seems to have LTE disabled. Although the service menu does show all the supported LTE bands, when I go to Settings-Mobile networks and try to change the enabled networks, only the following options are available:
- WCDMA only
- GSM only
- WCDMA/GSM mode
The question remains, how this is controlled and what can be done to enable the search and support for LTE networks.
Is this stored somewhere in some carrier settings file? Is it carrier specific, so that with some operators, this is enabled automatically, for others it's disabled? Can we change it somehow?
I am not feeling quite well about these options being disabled per-carrier.
Thanks.
I think flashing unbranded firmware will work for you.

I found in the UK, the option was missing on my UK Phones 4U firmware (350).
I thought it was some mods initially, but after applying the Greece FTF unbranded update (434), i got it back, even whilst running the same mods.
I flashed the UK 434 FTF update, and it's missing again, with the same mods.
These are only stock mods, status bar menu icons, reboot mod.
I will re flash the Greece Unbranded FTF and confirm if it's still missing, if it is not missing, for some reason, the UK unbranded FTF's (350 and 434) have it missing.
I flashed the .434 Nordic ftf and the LTE option is there. It wasn't on the original 3 rom.
I can't notice any difference at all that its a Nordic ftf and not a uk one, so I'll stick with this.
if LTE option is missing, it's only the option concealed but LTE is still there.
the culprit may be /vendor/overlay/com.android.phone-res.apk. try delete it after rooting.
otherwise, just ignore it and dial *#*#4636#*#* to enter what mode and you can see LTE options there.

This is controlled by your vendor's customisation of the ROM, I am guessing if they have removed LTE, then they do not support it. Therefore not sure why you would want to add it back, because you will not be able to use it. Because once your vendor supports LTE, I am certain they will send you out an update.
My phone has LTE, my provider has LTE. But I had no LTE on my phone, until I changed the plan I was on. And I couldn't force that on, because the vendor blocked that.
In addition as stated here any generic ROM should give you the phone/ROM in all it's glory, provided your vendor has LTE
Did you choose the correct setting in mobile network

I bought a Phones4U unbranded XZ a few days ago, with a T-Mob contract, and it DOES have the option, it had on when I was on 350 and it still has it now on 434. Perhaps it's related to the APN settings that the carrier sends you OTA? Obviously T-Mob is part of EE which has 4G so that could have done something.
I don't understand why your XZ doesn't have the settings though.
Are you sure you have the Z supporting LTE? There is a LTE and non LTE version on sale.

This was my next question, is it possible that the UK firmware reads the SIM card first and then 'knows' wether your current network is able to run LTE / 4G, if it's not, it only allows you to select the most appropriate setting, in my case GSM / WCDMA
Im on o2, not 4G, but the option was still selectable on my old Xperia V, and the Greece Unbranded Xperia Z FTF.
Have you tried a non 4G SIM / network in your phone to see if you get the option or not? Or could you...just to rule this out? If it is most likely APN related, then am not fussed, as soon as O2 has 4G, i should be able to utilize it
Cheers

Again only if your provider has locked this part out of the sim card, pretty crap if they did because this can be easily be controlled from within the network. Because when you scan it should show all networks around even ones you can't connect to, if not they have locked certain bands on the sim

Why does the C5502 offer LTE as an option in the mobile network settings?
Can others confirm this is the case with their phones?
Is this just because firmware is common to both or have I got a mislabelled C5503?
We don't have LTE here so can't test.

Either you are lucky to get a C5503 model out of the box (of a C5502) or the firmware that is currently installed in your phone is for a C5503
Hmmm, model number on phone and in settings says C5502. My wife's C5502 also has the LTE option. Both bought brand new. I imagine it's just a common firmware and there's no way to enable LTE. In service menu the "working bands" only list UMTS bands but LTE is presented as an option in 4636 menu.
Is there a software way to check the radio chip on my phone?
Hi all,
I have a Z3 Compact and just want to confirm it is capable of VoLTE? I read somewhere it is but cannot find much official information. If somebody could make it clear I would appreciate it.
Regards
http://www.xperiablog.net/specifications/2014-xperias/xperia-z3-compact/ it does
Good, is this supported on a hardware level or via a firmware update. When EE and Three launch their VoLTE service will the phone just support it without additional updates?
Regards,
I do have Z3 Compact with T-Mobile, but there is no VoLTE option
Using Xperia Z3 Compact on T-Mobile USA and trying to find which country will have firmware that has VoLTE option. My phone is from EU/Italy and I have Android 5.0.2 installed, but don't see any option to enable VoLTE. Any one has this option?
Check in /system/etc/customization/modem and you'll see that every firmware contains all modems.
Also, under Software Info in the Service menu it will show which modem is currently loaded.

I just went to Service menu and checked out Software info. It does list GSM/WCDMA/LTE, but how to find out if this phone will have Voice Over LTE? I used T-Mobile branded Z3 for a week and it had an option in "call settings" to put a check mark next to "Enable VoLTE". Once enabled, the signal stayed on LTE network instead of switching to 4G when making a call. The call itself connected faster and the quality was good. Right now even when I am on LTE and make a call, the signal drops down to 4G for the duration of the call, then after that goes back to LTE signal. I know Xperia Z3 phones support this feature on a hardware level, even white pages for Z3 Compact mentions VoLTE, but I can't find the setting. I read somewhere in UK, 2 carriers like EE, going to enable VoLTE in the near future, so I thought one of the UK firmware would have that enabled by then.
As far as I know VoLTE is carrier dependent. Actually maybe few around the world test this service even tough many phones are hardware ready for new standard. You can see the list here: http://en.wikipedia.org/wiki/VoLTE. Please let us know if you find out more.
The build for T-Mobile Germany has this option integrated.
~ Sony Xperia Z3 Compact ~
~ Samsung Galaxy Tab S 10.5 LTE ~
~ Huawei Ascend P6 ~
~ Acer Iconia A510 - CM12.1~

Interesting... Do you know if device from T-Mobile Germany is locked or unlocked? My device is unlocked and if I flash it with T-Mobile DE, would it lock the device?
I found this firmware on Xperifirm and it seems to be latest available. Is this the one you mentioned?
Device: Xperia Z3 Compact (D5803)
CDA: 1289-4143
Market: Germany
Operator: Telekom.de DE
Network: GLOBAL-LTE
Release: 23.2.A.0.278 / R11C
Size: 1.49 GB
Yes this is the firmware, I use.
You can remove most of the bloatware.
My device is locked.
I really don't now, if flashing this firmware will lock your device. I never used Flashtool.

I am trying to find out on another thread if flashing locked firmware on unlocked device, what happens. So I will know soon, but I heard that flashing firmware doesn't change SIM Lock, so if it was locked, it will still be locked and vise versa.
I have 2 questions:
1) Is the VoLTE option is in settings>call options and then it says "Enable VoLTE"?
2) Do you also have Wifi Calling?
Thanks
Sorry, I don't have SIM lock. I thought you meant a locked Bootloader.
Flashing another firmware doesn't effect SIM lock.
Yes, it is in settings - > calls
No Wifi calls.
BTW:
O2 Germany will activate VoLTE in the next days on all devices, which support this feature.
So I think, O2 Germany firmware should also have this option in settings - > calls

Thanks for the info! I have flashed my phone with few different firmware: UK, Generic DE and yours Telekom DE. I don't have that option. I checked everywhere... Looks like I may also need to have Telekom sim card and adjust some carrier settings. If nothing helps, I will flash back to original firmware and wait for some other solution.
Maybe this option is hidden, and only shown if your provider supports VoLTE.
Two of my colleagues have also a Z3c. One with Generic DE and O2 Germany SIM card and one with UK firmware, I don't now his provider.
I'll have a look into their settings.

T-Mobile USA has VoLTE and Wi-Fi Calling features. All the phones that are T-Moible branded have these features. That is why I was trying to flash your firmware Looks like not only firmware and hardware support plays a role, but also something that carrier has to enable support for Xperia Z3 Compact. My carrier has Xperia Z3 regular and it has VoLTE and Wi-Fi Calling, but the phone is too big for me.
Hi I found the post today about features that Android 5.1 will bring and looks like VoLTE might be one of them. http://www.geek.com/android/heres-what-changed-in-android-5-1-lollipop-1617837/
So can you tell me if this firm worked for z3c?
If so what's the link to download it with installation instructions

Hey. Did u unlock your bootloader. But how did u root. Please tell me the process u did. I am on 6.0.1 firmware
VoLTE on Z3C
I have Z3 Compact 6.0.1 (D5833 - India).
I have unlocked my bootloader, rooted, flashed Starhub 6.0.1 and have enabled VoLTE on my Z3 Compact.
Able to make and receive calls with the Reliance Jio sim.
A few days ago, my wife and I both got new Sony Xperia Z3 Compacts. We both activated on Cricket. Everything seems to be working well, but one of the phones shows it is connected to 4G and the other shows it is connected to LTE. Both phones have identical APN settings. Additionally, they have different options for 'preferred network type'. They one that shows LTE can choose
WCDMA only
GSM only
WCDMA (preferred)/GSM
LTE (preferred)/WCDMA/GSM.
The one that shows 4G can choose
4G (preferred)/3G/2G
3G only
3G (preferred)/2G
Can anyone shed some light on why they are showing up differently?
It seems that u have different types of z3c. Maybe one is with another region firmware.
Hit *#*#7378423#*#* on dialer and check under Service info - Software info if the customization version matches. If not, one phone has another region firmware. There is no difference, only that it shows 4g instead of lte and thats the same

They are both D5803, but yes, the customization version on the two are different. The LTE one says 1289-4696_R4C and the 4G one says 1288-6117_R7C. Is there a way to get them the same?

I am using the dual sim Exynos version of Note 9 and want to be able to force 4g LTE on either of the two sims as needed.
Can someone please advise how to do this on an unrooted phone? Thanks
Anyone?
I also found no solution. I think it's possible without root but no one is updating the Phone Information Apps. We need to get access at phone information 2 and not only on 1
Mine are both 4G / LTE. Inever need to switch the Sims around. Whichever I choose for days gets LTE. this is different from what I had in the Note 8. I was pleasantly surprised. Therefore it may be a settings issue for you. I have the Note 960F/D
you may try quickshortcutmaker app on exynis version and follow instructions in video
https://youtu.be/AdGAB4qRvYA
I feel like the Tasker App could handle this easily.
I dont understand the actual need.
Simply changing preferred network mode from LTE to 3G shall do to stop LTE on any sim.
I use LTE on both sims for calls
I use LTE for data on specific sim by making it as preferred sim for data.
Settings -- Networks -- Sim card manager shall help in these settings.
I am on exynos N960F Indian firmware.

So i will tell you
On my work i am located in a big Hall underground. The Provider i need down there is only coming in with -110 dB and less which is one LTE Bar. If i leave Automatic Mode it switches always in 2g Mode because of much higher Signal. So to get a nice experience and have LTE always available there is no other solution. The same kind of problem is on my other LTE Sim when on different Locations during the Day ! So i have no time to always switch sim cards so that sim2 is forcing lte !
And off course no one else knows this and so i benefit of this extremely fast connection where all others are crying because of no 4g connection

Because i use many banking and streaming apps it's not possible to root this time. Even with Magisk Hide they will not work.

Sorry but are you reading my Post?
I am talking LTE Only on Sim Slot 2 of any Samsung Phone out today. All the LTE Only Apps or the Phone Info Menu where they lead you is only working on Sim Slot 1.
I am sure there is a dial code like the one it gets you to the Phone1 Information Screen where you can change the bands. But only for Sim 2 (Phone info 2) on Samsung.
So again LTE Only on sim Slot 2 on Samsung Duos Versions is not Possible @ the moment without Root!
If there is any Dev out there you would be the first One to create an app where Phone INFO 2 is possible to change! Or just find the right hidden code for that i know it's there like the Phone Information 1
Hi,
There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

Hey thanks for that. I really was in hope this could work but that would have bean to easy. Unfortunately it's not changing bands after deselecting undefined and than choose some network mode it remains to the same band but it looses the mobile data symbol (but still remains in same band).

This code and all Codes are not working on European Samsung Devices with Android 9 .
I Even Rooted my Galaxy Note 9 and all the hidden codes are Not working ! Even Samsung Phone Info App or other Apps are not working with Latest Android 9.
Only way is Root and Custom Rom like Alex Dev Rom where the CSC is Modified. There it was possible to change both Sim to LTE Only ! But as told before with Root
i loose to many services which are detected even with Magisk . So my next Phone will not be Samsung anymore because of that.
Hi team,
This is a Global Mi 9T Pro, Miui 10.3.2, bootloader is not unlocked.
LTE 4G works, however no "voice over" - it reverts to 3G for voice calls.
*#*#86583#*#* results in "the number you have called is not connected", using both SIM 1 and SIM 2, have tried 2 different SIMs that show "VoLTE" on Reno Oppo Z and GS8. 4G switcher app shows "VoLTE not provisioned". Any suggestions on how to enable VoLTE? I have tried a factory reset once...
Thanks

I'm in Brazil carrier Tim, unfortunately there's no specific MBNLoader file for this carrier, so I selected the generic Brazil MBNLoader, it wasn't enough to turn ON VolTE in calls though, it reverts back to 3G or 2G
any other ideas?
PS found a post on another forum that says the Malaysian MBNLoader will be fully compatible with the carrier TIM on Brazil. I tried it and it worked perfectly, now I have VolTE. GG

I think what you're asking is if the MBNLoader changes automatically depending on geolocation or when a new SIM card is inserted. TBH I don't know. But if I would have to guess I'm guessing it is a setting that you select when turn on the device for the first time, and that remains selected even if you insert a new SIM card. Lemme know if i've misinterpreted your question.
