Service Mode / LTE Engineering Mode - Verizon Samsung Galaxy S6

Can someone please confirm if Service Mode dial codes work on Verizon S6 (Edge) variant? There are a few of them:
*#0011#
or
*#27663368378#
or
*#197328640#
or
*#2263#
If someone isn't sure what this does, it allows you to view which LTE frequency you're connected, what's the Bandwidth of the active LTE channel, what's the signal level and quality, if the Carrier Aggregation has been activated, even allows you to lock onto certain LTE bands, etc. So for example, if LTE on Band 13 is congested, you can force the phone onto Band 4, or Band 2, etc.
This is what it looks like on T-Mobile variant:

Thanks a lot!

Tried all your codes. None of them work.

Thanks for the response. Once again we'll have to root the phone in order to enable this.
Verizon's been blocking this built in feature from their users for at least 3 years now... sigh

They've sometimes let the codes work, but neutered what's available for info/options underneath. I hate that Verizon does this.

I have a rooted Verizon S5 (not Edge). I tried your codes and, as expected, they didn't work.
What would I need to do as root to get them to work?

The instructions in milan's thread in the general section should work for your device. It's worth a shot.

YES! This worked. I can now access the Service Mode menus after setting the EFS file, as mentioned. Cool! Thanks!
NOTE: I had to use this code.
*#27663368378#

What do you mean by setting the EFS file?

I get an error: Connection problem or invalid MMI code.
my connection is fine, how can I fix my MMI code?

service mode menu
ok so i can access the service mode. but in the up right hand corner where it says "more" what do i enter in the input key option to access the menu for the service mode???

Perhaps you're better off not knowing, I stumbled across you because I'm ready after a long as time of rooting, lurking silently thru the forums, soaking myself up with information, and bricking a couple of devices, to add all the bands to my klte. You're eagerness only denounces your likelihood of messing things up and conning back like OMG WWIII somebody please HHHEEELLLPPPP!!! You're trailing dangerous territory not knowing

[Q] Force 2g/EDGE on LG Phoenix???

So, I have extremely crappy 3G coverage at my home sometimes, and it completely prohibits me from speaking to people. I have called AT&T tech support and basically they said they know the transmitter in my area has a problem, and I can go pound sand. A microcell "might" work, but I have heard they have problems on DSL lines, and I really don't feel it is fair that I should have to pay extra for what my service provider should be supplying anyways. But enough with my anger at my provider.....
I just purchased this LG Phoenix and the way I used to get around my 3G problem previously was that I would force 2g/EDGE on my old BlackBerry Bold 9000. Not only that, but it used to save LOTS of battery power. On this phone though, it wouldn't appear you can't disable 3G. I have checked in the settings, and I have tried a couple of different Apps in the android market to no avail.
Have I missed something, or am I just going to have to wait months till developers start rolling out custom ROMs or the like? I really like this phone other than the fact that I can barely make calls on it at my house. Which negates the purpose of owning a phone I suppose.
Any help would be greatly appreciated.
Well, I see nobody has any answers. That's OK, because I found out what I needed.
Basically AT&T disabled the option to choose your data network within the operating system. (Along with side-loading, which I will admit they fixed with the 2.2.2 update)
What I need to access is in one of the two following menu options on this device:
{
"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"
}
Unfortunately, I have been told that I can deal with it and pound sand, or wait until a custom ROM is adapted to this device.
Sooooo.....
In case anybody actually gives a crap, I have found an answer to my dilemma.
You can force 2g/3g transmitter usage though the hidden menu on your phones.
First, dial: 3845#*505# (Phoenix) 3845#*506# (Thrive)
Scroll down to the "Network Mode" selection and enter.
Automatic is the first selection in that menu. This is what are phones are set to by default. This allows the phone to switch between whatever it thinks is the best wireless network to use. Unfortunately, I can barely talk to people when I have 1 bar of signal in my house, and very often the phone won't switch over to 2g when 3g signal is very weak. 2g also saves A LOT on battery power.
If you want to choose the wireless mode your phone, scroll down to the bottom of that menu and you will find the following options:
- If you choose WCDMA Only, you will connect to the 3G network
- If you choose GSM Only, you will connect to the 2G/EDGE network
I hope this is helpful to somebody other than just me.
Is there an easier way of doing this rather than inputting that code each and every time?
Bueller? Bueller?

[Q] IM-A890L Hidden code RF band selection help!?

My phone is the Vega Secret Note. The phone does work, and I am able to access LTE 2100 here in Canada with it.
I just want to double check if there isn't any bands that could be locked... I've read somewhere on Naver that it does support LTE 2600. And since LTE 2600 is LTE MAX here it would be my prefered choice if it's available somehow on my phone. I'm wondering if it could be a hidden band that needs to be selected....
*#*#4636#*#* Does work, but there is no band selection on that menu
I am trying to get RF band selection menu.
I know Samsung usually uses : *#*#2263#*#*
But there is limited info for Vega phones on here and around the web....
the closest I came to was using thise code # # 7593 # but there is no LTE band selection menu.
I found this thread assuming since these codes are also from Vega that most would work, but only 2-3 works ...

5G Standalone TMobile Converted to Global

Before I converted to Global from Stock TMobile i was able to select 5G Standalone. Now my only choice is 2G/3G/4G/5G Automatic.
I have the new SIM card which is supposed to be working for Standalone mode. Is there a way to get this option on my phone without root?
I do show 5G on the status bar on top but every cell mapper or signal app i try does not show 5G connected.
I am Worried I am not really receiving 5G although i have checked the speed and I get between 115 to 250 MBPS so I assume this is not 4G?
OK to I got my own answer and I hope this helps anyone else in the same situation.
Went into the phone information settings *#*#4636#*#* changed the preferred network type to NR/LTE
then I went to preferred network type in the sim card settings and it showed 5G/LTE. As long as you leave it that way it will not change after a re-boot. If you change that setting to 2G/3G/4G/5G again you will not be able to select 5G/LTE again unless you repeat the setting in the phone information.
Now my cell mapper shows I am connected to 5G.
i bet you can fix this using qpst. there are missing/different settings in the files I've seen for global vs Tmobile versions.
i actually edited my original Tmobile files to enable some of the bands that were disabled and to allow 5g on other carriers when traveling.
when connected to stand alone 5g your phone status will look like this -

VOLTE or no VOLTE which is it? Plz help

The Pixel 2 I purchased for my father stopped working a few days ago, with the 3G shutdown going on. His carrier is Consumer Cellular which uses AT&T towers exclusively. So from what I understand phones on AT&T's network will be required to have VOLTE. I'm a bit confused as to whether or not this phone is indeed capable of using VOLTE. In the settings menu under network type, the only two options shown, are 3G or LTE, and when I pull up the secret menu via the dialer app, it shows this phone is not provisioned for VOLTE. Can that be changed? See attachment, even AT&T's own documentation states that after the 3G shutdown, the Pixel 2 will continue to work on their network. Currently, with the phone set to LTE mode, internet is working at full 4G speeds, but the phone will not dial out or can receive calls. It fails instantly. Now when the phone is put in 3G mode, both incoming and outgoing calls can be made no problem, but internet is much slower. Predicatably the Consumer Celluar agents are clueless, and since were not account holders with AT&T, they won't talk to me. So at this point, we either find a way to get the Pixel 2 working, or I buy him a new phone. He wants to stay with Consumer Cellular. If anyone has any insight, would be greatly appreciated. SO FRUSTRATING!!
thanks

How to enable volte & vowifi on pixel 2 xl - Google Pixel Community

FWIW, I have the exact same issue with my Galaxy S8 on Consumer Cellular. It's on AT&T's list of supported devices but calls fail immediately when on LTE network. Switching to 3G makes calls work for now, but I know that's only a temporary solution. When I put in the IMEI on Consumer Cellular's website, it even says the phone is supported!
We have been very happy with Consumer Cellular in the past, but our experience with this issue has been really frustrating.
We switched to T-Mobile Prepaid and everything worked as soon as we put in the new SIM: VoLTE, WiFi Calling, etc. Goodbye Consumer Cellular I guess.

My Moto g 5g doesn't give me the "select preferred network option". I want to use 4g

I bought this unlocked from Amazon. Using boost mobile infinite
I called boost they said it should be able to be done from the phone
I called Motorola they said call boost

What is your model number? Is this a 5G Plus, or Stylus, or...?
We have device specific sections that you'll probably get more help in, so if we know where this thread needs to go, we can move it for you.

It's regular moto g 5g 2022 that is the model name.
You should have a toggle for 'Allow 5G' that will do what you want. If not, use the dial code *#*#4636#*#* and pick an appropriate config under Phone information -> Set Preferred Network Type that does not start with 'NR'.

Awesome. Where can I find the breakdowns of each network type. Which one is 3g. I think 4g is LTE
On the TMO network 2G is GSM, 3G is WCDMA, LTE is 4G, and NR is 5G. CDMA/EvDo would be for Verizon 2G/3G. TDSCDMA was developed in China so you won't see it deployed in the US.
