Hi,
Need some assistance regarding a setting for the N7105. If someone could kindly input in their dialer *#9090# and tell me what the default settings are (please do not select anything). Then press back button to cancel.
The default settings are the ones with an asterisk in between two brackets, as seen here (*)
I accidentally selected
[1]DM/DUM over HS-USB

when checking out the service mode/diag config using the above dialer code.
On another matter, also in regards to the N7105. Has anyone noticed in Settings>About Device>Status, that their N7105's Mobile network type is consistently LTE:14
Reason being, is that when my phone is displaying that status, my signal bar shows only 1 bar. However, it does sometimes show full bars and the Mobile network type then displays 'UMTS:3'
I am in an area that can receive 4G signals (Sydney, Australia), but I was under the impression that my phone should be idle in UMTS:3 mode for general calls and SMS; and switching to LTE:14 when I activate mobile data and thus use 4G signal.
I am able to make calls/sms and connect to 4G with no problems, however am concerned that since it tends to be in LTE:14 mode the most that it may drain the battery more than if it were in UMTS:3
Thanks in advance.

Just dialing *#9090# won't change anything, so long as you don't touch any of the options. Simply dial it, look at the defaults, and then press back button to cancel/close page.
Thanks in advance to those who can help.
Mine is on HSDPA:9, i'm using the N7105 also.
Even if its using LTE band, as long as your not downloading data, it wont kill your battery.
Mine is
[2]DM/DUN over HSIC &
[5] DBG MSG ON

The T-Mobile G2 has *#*#4636#*#* to enter the diagnostics function.
Would there be anyone out there that could give me the best (performance) settting options that I should select with my G2 when in the diagnostic mode? Thanks in advance!

I mostly use WCDMA only. You also can downlaod AnyCut from the market and load the shortcut PHONE INFO and it will do the same thing as dialing those numbers
Sent from my T-Mobile G2 using XDA App
Also too, why do I use WCDMA only is for it only looks for HSPA+. That way if I'm say in walmart it does not go back and forth on HSPA+ and Edge all the time. If its not 100% HSPA+ than my cell won't connect and waste that little bit of battery roaming
Sent from my T-Mobile G2 using XDA App
If you're in a city with good HSPA or 3G coverage, use WCDMA preferred. If you're in a city with spotty 3G/HSPA coverage, use GSM auto (PRL). The first will connect to 3G/HSPA if at all possible. The second option needs to reach a higher signal threshold before it switches to 3G/HSPA. I've tested both.

I know this is a newb question but what does it mean when you see all of those numbers and symbols? Is it a number to call or text? I want to know because I say it under the OTA post in order to "Check In" but I have no idea what it means or how to use it.
Its basiclly a code to get into phone information on your cell

You enter it just like a phone call, then it will present the Phone Info menus to you. To checkin, it's the same sort of thing, just dial *#*#2432546#*#*
Hope that helps.
I've noticed in the menu options, there is an option to keep the phone in 2G mode only. On the other hand, is there any way to keep the phone in 3G / 3.5 / 4G mode? Any software that can do this?

The phone will only switch to 2G if faster speeds are not available. The 2G mode option allows you to prevent the phone from switching to faster (and more battery consuming) data connections....
From the dialer, you can type in *#*#4636#*#* to bring up some "secret" settings. From there you can configure your phone to only use 3G.

Go into phone info. From there if you scroll down a bit you will see a text that says something like "GSM/CDMA auto". Press that and you should get a drop down menu. Change the setting to "CDMA only". That should work.

Not sure how that disables 2G (1xRTT). Unless I'm mistaken, both 1xRTT (2G) and EVDO (3G) run on top of CDMA.
Also, you can get to this from settings->wireless & networks->More...->Mobile Networks->Network Mode
There you can select LTE/CDMA or CDMA.
And it always sticks
I just play with my S3 I747 and find out how to temporaly remove RAT restriction.
Click phone then punch code : *#197328640# ->Umts->Debag Screen->Phone Control->Network Lock->Rat_Free_Supporting ON
After you click this you see " Now RAT Free Supporting". Click back button and try setting radio by pressing *#2263#.
RTA will lock back after restarting.
could you explain what "RAT restriction" is and what removing it will provide?

Here is a thread that talks about RAT restrictions. It appears to have to do with restricting access to certain bands, but I am swimming in waters that are deeper than my skills will allow.

I gonna do a run for this later today to see if it will actually work for allowing band selection and sticking.
It seemed to work for me, but it's only been a couple of minutes so far after turning off LTE. BTW, the first menu is "UMTS", not "Units".

Any suggestions on how to make these changes permanent without rooting?
Since there is now a known code to lift restrictions until reboot, I hope some dev will figure out a way on stock based roms (both stock and mods), as well as AOSP based, to make it permanent. I have tried AOKP and CM10 in hopes the LTE and 2G toggles would work but no dice with AT&T SGS3.

Given the issue at hand, it is most likely a deeply embedded setting that will not be available to standard user base (non rooted), henceforth root access or even on a programming level will be needed to make the necessary changes. How the changes will be made available, if it is done, will depend on what was needed to make it permanent. This raises the question of where is this restriction coded into the AT&T SGS3. Is it firmware, ROM, SIM related, Radio? Seriously doubt it is hardware itself since there are ways to get around the restriction.

Testing this method now. So far I am running on 2G. I will give it at least a couple of hours and will update this post accordingly.
Update: I was messing around and decided to save this USSD (the official name of these secret dialer codes) in my contacts. From dialer you can start pressing *#1 and when it appears just press it. This gives quick access should you need to change radios often. I also want to add that instead of going back into *#2263# you can also select the band from *#197328640#. If you want to change it immediately, then once you get the confirmation "Now RAT Free Supporting" press the menu key on the left of the Home button. Select back and repeat again to go back again. Then, instead of choosing Network Lock choose Network Control-->Band Selection. This takes you to the same menu that *#2263# does and you can select accordingly.
@norbarb...perhaps you can update your OP to reflect that you can stay within the original selection instead of *#2263# and just go back twice to access the band selection. It is just one more way of doing things.
I also did the test of rebooting my phone. As mentioned by norbarb, if you have rebooted the RAT restriction is back in place. Regardless of which option you take to the band selection it will show RAT restriction until you follow the OPs steps again to remove restriction. Have not found a way for permanent removal of the restriction yet (I am optimistic and really want this permanent so I will look very hard to find a solution.). Also when I rebooted I had GSM 2G only selected prior and I kept the option upon reboot so only the RAT restriction is reset...not the network band settings.
Update 2: After 4 hours I am still on 2G Edge. I am in a very good LTE location so this is definitely the most promising outlook. I have found that I despite my love for the look of AOSP roms, the inability to turn on 2G at all will keep me with TW for now. Thankfully I do not mind the look of TW and with root, I can kill the Bloatware. I will look at all of the options in the *#197328640# menus and see if there is anything that may can be applied for permanent access. I also wonder if the secret to overriding the lack of options for network choices in *#*#4636#*#* will be here as well as this would more preferable to shut down LTE only.

Isn't the problem with doing this, say if you disable LTE and only select HSPA, it wont go to any 2G networks if you are out of coverage. Because its not on 'automatic', its on HSPA. So if you are out of a service zone of HSPA, then you dont have anything to fall back to.
If only there was a way to disable LTE, and use the other networks 'automatically'.

That is the problem. However, AT&T in their infinite focus on trying to force users to their networks of choice has purposely had the ability to do network selections disabled. Under normal circumstances in android devices the option of network selection is under settings and mobile networks option. This is removed I am sure at AT&T's request. The other way to access this is to use USSD *#*#4636#*#* in dialer and select "Device Information" which will give you an option to choose a network preference. While the USSD works the option to select network preference does not work.
At least with the option to unlock RAT and using USSD *#2263#, it gives some sort of ability to choose a network. For me this is perfect since I want the 2G only due to poor 3G and LTE signals at work. However you are right that it is not convenient if you just want LTE off. For the moment there is no known way to obtain this option on the AT&T SGS3.

Yep. I also think it's something to do with AT&T network setup. Because on AOSP ROM's we can't toggle LTE either. But the same ROM on a Canadian model phone will work just fine.
Even though the iphone has an LTE toggle. At least I read somewhere that it does.

It has nothing to do with the network setup...it is the carrier forcing restrictions on their customers. I have had three other android phones (including my wifes) in the last three years. All of them were restricted from choosing the network from stock rom. The moment I uploaded a ROM such as CM or other AOSP Roms I was magically able to do a network select. I even had to Windows phones (6.1 and 6.5) and both of them were stripped but with some registry edits I was able to add the option back to select between 3G/2G and 2g only. It is AT&T's way and they are notorious for it.
On a side note, I would not be surprised if AT&T is the primary corporate network that pushed for this network SIM lock ruling by the Congressional Librarian. Of all the carriers they have the most to lose.

I have been testing this for the last 4 hours and it does seem to work. Went to 2g only area and it switched perfectly to 2G and reverted back to 3g when I left the area. However I am not able to do GSM ONLY (2G only) using this method. You will have to follow the instructions on this thread for that.

It could result in battery savings and reduced dropped calls. For instance, I am often in and out of areas with little to no bandwidths under LTE. At default, my phone would always looking for an LTE signal which means my battery takes a pounding. By having my phone only look for 2G/3G, I do not take as large of a battery hit. Besides that, LTE does consume more power. For the most part I leave my phone with LTE off because the data speed is not crucial for me. At home I have a really fast WiFi network so it is better to be on it anyway while at home.

OK Thanks. But under Settings/More Networks/Mobile Networks/Network Mode there are 13 "band" combination choices. Do those choices not provide what you''re looking for (i.e.2G/3G)?
I've never changed mine, so I'm curious
So I have always had Lte on my Galaxy but now under mobile network type it says I have UMTS:3. Can anyone tell me what that even means. Also my moms house as well as my dads house both have LTE coverage, yet I can longer get LTE. When I put data on my network changes to HSpAP:15 which I also dont know what means, and yet it says 4G on the status bar. Has anyone ever had any of these problems or could enlighten me on what all of these mean?
Need a little more info, please. What ROM are you using, any mods made to your phone, stuff like that.
Yea, need more info.
I'm going to leave the book here for someone else to write, but when not on LTE, it's not unusual for your phone to read UTMS3 or HPSAP15 and for your phone to read as 4G when on HPSAP15. It's technically still 3G, more like 3G and 1/2, but ATT choose to call it 4G. You will usually see this on ATT stock ROMS and some custom ROMS, but will find it correctly reading as 3G on other custom ROMS.
Sorry for having little info there. But Im on stock rom with stock kernel. Im rooted and have done a few mods to it but thats about it. Its just weird because on ATT LTE map I am clearly surrounded by LTE coverage but am not getting it. Im going to try and put my SIM card in my sisters phone and see if I get LTE on that.

Is that going to be the first time you've removed the SIM card?
Search "how to bypass RAT restriction"on the s3 and bypass it. Then use dialer code *#2263#. Select lte, lte all. This could get your lte back. You could also do the same got gsm and wcdma while your in there. After you finish your selections, reboot.

That's the direction I was going when I asked about the SIM card. Removing the SIM can temporarily remove the RAT restrictions, which can allow the settings to be changed.
The RAT restrictions can be removed first by dialing *#197328640#, then hitting the numbers 11865.
Then you can dial the user code *#2263# then hit 1 for Automatic.
Please do not select lte. You cannot make calls on AT&T yet on LTE. The phone always switches back to 4G or whatever when there is a call, but never LTE). If you select LTE, then it will always be on LTE, and now you will have LTE and no phone calls. You need to select Automatic, so that the phone can dictate to you and call all the shots the way AT&T intended.
I beg to partially differ. You should select all lte, to make sure those bands are active. If they aren't, automatic won't use them.

I'm on touchwiz. I can make calls on everything but LTE. When I set my phone, GSM always stays on Edge, WCDMA always stays on 4G (what ATT calls it) and LTE always stays on 4G LTE. They never change unless its on Automatic.

Check your imei in settings. If it's a zero, you'll need to inject it back in; there's a guide for that.

Dialer code *#2263#

Select Wcdma all
Back
Select LTE
Select LTE all
Back
Select Automatic
Back key on the phone
Reboot
You must be on a Touchwiz ROM and use the stock phone dialer.

Open the dialer, dial *#*#4636#*#*, go to "Phone information", scroll down and under "Set preferred network type:" select "WCDMA preferred", press back button two times and restart your phone.
If you are still not getting the 3G/H icon in the corner of your screen, call your provider...
I did and they did something and told me to remove the battery and restart and then I got the H icon again.
