Check what band you are connecting with your Xperia!

I found there are a lot of "debug" apps in the firmware for Z3,
and I'll introduce the most interesting one - "Tech Mode by Sony"!
With "Tech Mode by Sony", you can check what band you are connecting only with your Xperia.
I only confirmed "Tech Mode by Sony" aka TechMode.apk is avairable in the firmware for Z3 / Z3 Compact 23.0.A.2.98 / 23.0.A.2.105.
Here is extracted files from Z3 D6603 23.0.A.2.105: Download
[UPDATE]
You can get Tech Mode for Z1 or Z2 by flashing/downloading Customized UK ftf
How to check connecting band
1. Dial
Code:
*#*#*386#*#*
or
Code:
*#*#*585*0000#*#*
2. "Tech Mode by Sony" will be opened, tap what you are connecting.
e.g. If you want to check LTE band, tap LTE and if you want to check W-CDMA band, tap UMTS.

3. Check "Serv EARFCN" for LTE or "UARFCN" for UMTS
4. Open LG Space or some other apps such as EARFCN Calculator
e.g. Type number of "Serv EARFCN" to "Earfcn" of LG Space and click "Frequency ...".
Then you wil get band info like this:
For UMTS, click "UMTS Frequency" tab.
This is very useful if you are interested in network or unlocking bands.

Great! Tks for sharing this....

Anyway, tested on Z1 4.4.4 .133 firmware and all show N/A on the app. Some are display like IMEI......

Very helpful for me, T-Mobile would intermittently switch me to LTE Band 4 where signal was low instead of keeping me on Band 12 which gave me full signal. After disabling Bands 2&4, I am always on Band 12 now with full signal.

Not working for 5.1.1 on 6603

Great found!
Thank you so much my friend!!

It works on the Z2 with 5.1.1 ROM 264
Download the apk file, place it in system apps as 755 and reboot.. (you need custom kernel to write in system folder, or deactivate protection)
Thanks a lot
All other apps I've tried failed to read the earfcn Nr.

Hi @AndroPlus, I'm trying on a Z3C running stock MM 23.5.A.1.291 (booloader locked) D5803.
Both strings don't work. I mean, when I digit the last character "*" all the text I have digit (in the text dial number) is automatically deleted.
Is the apk working in this case?
Thanks

Domestic Unlock Question

Hello Everyone,
I currently have a SPH-L720 that I performed the international sim-unlock on and currently use it in the UK. I plan to use it when I return to the states on Verizon, but am curious if I need to perform the Domestic Sim-unlock and change the LTE bands under the hidden dialer menu or should it work automatically since the phone is currently carrier unlocked and then only need to change the LTE bands? Thanks!

It doesn't support the Verizon LTE bands to begin with. Pretty sure you will never have 4G, if I'm wrong kindly point me to the info.

Ah ok I was under the assumption that I was able to modify my LTE bands as I saw on an S5 tutorial.

Would you mind linking that tutorial? As far as I know you can only change them to bands that are already supported by the device.

Hello.
The Nexus 4 never officially supported LTE. Some people discovered that there was partial support in the chipset and figured out how to enable it. However it only works on a limited frequency range and you have to know if the cell sites near you have the right frequency band. I never bothered figuring it out for myself as HSDPA+ is fast enough for me and I only have a small amount of monthly data to use anyway.
You need to use older versions of the baseband/modem as the most recent ones disabled the possible LTE modes. Whether older versions of the baseband are compatible with community ROMs based on 6.0 and up I don't know. I haven't seen any discussion for a while now. Phones with good supported LTE have been common for a long time and I suspect anyone who really needed LTE has moved on.

Band 4 LTE works just fine, problem is, I think Tmo in the US is the only carrier that supports it (thankfully I am in the US and on T-mo in that case). Any ROM with a Hybrid Modem will work. I am on latest 7.1.1_r4 Nitrogen OS and is works fine: http://forum.xda-developers.com/nexus-4/development/rom-nitrogen-os-n-substratum-10-09-2016-t3459341
Make sure LTE shows as enabled: http://forum.xda-developers.com/nexus-4/general/updated-zip-one-lte-enabler-flash-one-t2358931

Hi
Good news!, in latest 7.1.1_r4 Nitrogen OS, this ROM has build.prop modified by default with LTE option enabled in mobile network menu. But this ROM has modem device only for 3G, so i flashed this file and 4G LTE it's back again on band 4!

No band info avaible on Nougat for GT-i9505

Hi,
I switch yesterday to Nougat from the last CM13. I try many Nougat build, and i get the same problem on all, i can't get the LTE band information.
In CM13 i used tool like "LTE Discovery" to grab it, but in any nougat build i was unable, app tell me some impossible info like Band 1 (2100mhz, this band is not in used for LTE in my country) or stay on unknow band.
I try many tool like LTE Discovery and the result was the same.
Someone know why ?

Did you upgrade your modem to the latest version before switching Android versions? If your version is too old, issues like this can result. Also, when you flashed the Android 7.x ROM, did you start from scratch, i.e. wiped system, data, and internal storage, before flashing? This is pretty much required when changing from one Android version to another.

Off course, i did all of this, i also tested the last 5 modem releases with the same result.

So what happens when you use a different ROM, such as the JDC Team's AOSP?

I have test LineageOS official, unnofficial and the optimized lineage by JDC, all based on lineage. I have download the JDC AOSP but not tested yet.

Insted of the 4G logo normaly this is the band number, sometime i'm on band 1, an impossible thing because this band isn't in use in my country ^^
Also i can say i have no problem to make a phone call or send sms.
I have try to roll back to CM13 and all was working normaly.

The real test is to see if you can get onto the Internet since some carriers route calls through the 3G network. However, have you checked your APN? This sounds like a configuration issue.

Yes i have check my APN and i'm sure it's ok.
I'm sure to be in 4G for data (see the screenshot) and for call i'm also sure to be in 2G or 3G because i don't have VoLTE for the moment (but it's another problem ^^)

You're getting high speed data, which means the LTE radio is working correctly. I believe your issue is related to the hardware drivers being used in the kernel. The problem isn't with Android itself or LTE Discovery, as I installed LTE Discovery just now on my Nexus 6 which runs Android 7.x. It's still being supported and thus includes up to date drivers, and my LTE radio reported the band number. You can try a different kernel and see if that resolves your issue, but you may simply have to live without the band data.

Thanks for your answers, maybe i can report the bug somewhere ?

LineageOS I believe has a Gerrit for bug reports.

[OREO] [G950F/G955F] [Duos Also] Select a specific band on your Exynos S8 or S8+

The Samsung Galaxy S8 and S8+ were recently updated to Android Oreo, and among its new features includes a full band selector (replacing the old service menu that was disabled with the security patch of November / 2017)
This mode lets you choose a specific network (as does the test menu in AOSP) and also choose a band specified within all supported.
Now, the only known way to enter this menu is through an activity manager (Nova Launcher or Quickshortcutmaker for giving examples) and look for the com.samsung.HiddenNetworkSetting app
When you find the activity, you must execute it and the next window will appear:
https:// imgur .com/a/61DJo
Where you can choose the network mode. If you open the side menu, you will see the other 2 options (Band Selection and 5G SA Mode) then select "Band Selection" and the following will appear:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Here you can choose the available bands, and then activate the slider that says "Selection". In this way, the band chosen as the default (Remember that if you select only one of the bands, you will not have CA)
I remember again that this method only works with builds based on Android 8.0 Oreo (RAP or RB7)
I remember again that this method only works with the builds based on Android 8.0 Oreo (RAP or RB7) and I do not know if it will work on other models besides the international variants of the Galaxy S8 or S8+ (SM-G950F / FD and SM-G955F / FD)
That is all! For now, I will be alert to possible doubts, but I remember that this app is only available through a hidden activity within the Oreo update, and I do not know if it will be maintained in successive updates. I will continue informing.

Thank you so much

Thank you very much for this useful info and for some unknown reason I am not getting Band 40 in band selection menu even when I am 100% sure this phone support TDD band 40
