Show Which GSM UMTS Frequency is Connected?

Hello,
I have searched all over the web about how to display which GSM or UMTS bands I am connected and using at the moment (i.e. 850mhz, 1900mhz, etc), but the ibky thing I have found is to get into the phone's service menu, but every time I try, either nothing works or I receive MMI code invalid.
Is there an app that cab do this for me? I just want to know which frequency O am using in determining what other international phones can work in my area on 3g. I am on T-Mobile and I know they have been converting to the 1900mhz band for some time now, so I want to confirm for sure.
*#*#INFO#*#* does not reveal the band, and *#*#SERVICE#*#* does nothing ...
Please help.
Thank you.

Try #*#*4636*#*#

Yeah #*#*4636*#*# does nothing either. BTW 4636 is INFO on the dialer.
*#*#4636#*#* works, but that doesn't show the frequency in use.

Disable LTE permanently?

Is there a way to disable LTE functionality permantently (software side) on the i9505?
I am in a low coverage area and with LTE enabled my battery drains much much quicker than with GSM - in Idle!
UMTS would be fine enough, I don't need the speed of LTE.
The only way I've found so far is *#*#INFO#*#* in phone mode.
But after a reboot everything's gone.
Any idea?
Thanks!

Settings /more /mobile networks /network mode
You can choose what ever you want
I just have it on WCDMA and GSM cos there's no LTE where I am.

Thanks, but I only have a checkbox "Use 2G only".
I forgot to mention I am on the latest Google Edition ROM.

Oh right.
Sorry no idea how to do it on GE, don't know if you can.
If you have exposed framework you can install Gravity Box, that gives you loads of CyanogenMod features but not sure about network modes.

[How to] Disable LTE or 4G

This is useful if you have a weak LTE signal or just don't need it always on. I found this tutorial on a different website for another galaxy phone and it works on the Note 3.
1. Turn off your phone and take out your sim card.
2. Turn on your phone with no sim card and wait a minute or two for it to turn on and settle down.
3. Go to the dialer and dial *#2263#
You should see a menu with band selections. The current setting is "Automatic".
(You have to use the menu key to select your options by using "Key Input" to type the number you want)
If you switch to "GSM All", you will be EDGE (2G).
If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Power off the phone again and put your sim card back. Upon reboot you should see your new setting in effect.

I get a service mode that says rat selection is restricted...
However *#*#4636#*#* will allow you to select whatever band you so choose. Although lte only doesn't allow voice calls

If your sim card is out when trying to access the menu it shouldn't say restricted.

I tried the above on my S4 and couldn't get LTE back was stuck on wcdma preferred. Google resulted in a ton of information. Ultimately hard reset needed.

Yeah that code doesn't work for me. It never worked for my note 2 or note 1 so I wouldn't recommend doing it.

Thank you inmotion! This code actually worked better for me on my Samsung Galaxy Note 3. I didn't even have to pull out my SIM card or reboot. Just dial in the code, go to Device Info and change the preferred radio network type. It changes the radio on the fly in real time, and can be seen at the top.

Since Android 4.3 and on the option to disable LTE/4G has been removed from all AT&T Android devices.

Actually it was before that. Could not do it on my note 1. Would always get RAT restricted. This was on at&t. Other networks were able to use those codes and make the switch.

1. Download the free Phone info app from the Google Play Store and install it
2. Choose the Phone Information tab and notice the "Set preferred network type" option at the bottom, marked with an arrow at the right of the drop-down menu
3. Tap on the preferred network listing currently in use, and choose the "CDMA auto (PRL)" option from the drop-down list
4. You should be now maintaining connection to only Verizon's 3G network, and whenever you need to use data, you can switch back to LTE for the duration of it
There are numerous other apps and widgets at the Play Store that claim to do the 2G/3G/4G switch, but many users on Verizon have confirmed the Phone info app to be the only method allowing them to reliably turn off the 4G LTE on their Samsung Galaxy S IIIs.

Does anyone know how to do a network reset? Because I connect to any Data at all no 4G LTE or 3G none of those. I can't send or receive pictures and go on the internet. I tired taking out Sim card for awhile and still didn't work. Does anyone know what to do? And how to reset network?

Having network issue with octa version, any help?

My provider only uses HSPA +/LTE, the phone always downgrades to hspa (non +) and sometimes 3g which my provider doesn't support so I loose my data connection and it sometimes takes a really long time for it to go back to the proper hspa+ that I need it to use all the time. Anybody knows if I can somehow force the phone to use hspa+ 100% of the time?
Thanks

Switch to HSPA+ only mode. Probably wont work with phone calls unless you VOIP.

How??

You must be mixing up HSPA+ with LTE. I don't think there's a way to choose between HSPA/HSPA+/UMTS, they're all considered 3G or WCDMA (unless you're in Canada.. carriers lie here, those networks shown as 4G are actually 3G)
Sent from my SM-N900W8

Well when my phone shows 3g or hspa I cant get anything to load online, it will stay on this mode for a while sometimes and then as soon as the phone shows hspa+ everything loads perfect. Every othere phone I have bought from Bell mobility in canada show hspa+ all the time.

I just tried making a call with my Note 3 (S800) and it was able to make a call on HSPA+ on TELUS. I think either your location doesn't have good HSPA+ signal / it's overloaded or there's a problem with the phone, does it support all the 3G frequencies Bell uses?

I know, you said "switch to HSPA+ only but you may not be able to make calls." You can switch to LTE only and you will not be able to make calls. You can make calls on HSPA+.

call #9090#.
Will bring up configuration menu.
Should be tons of radio mode options. One should be HSPA+ only.

Must be the wrong code, *9090* doesn't do anything and *#9090# brings me to a service menu which has no radio settings
Sent from my SM-N900 using XDA Premium 4 mobile app

Bell mobility uses "UMTS/HSPA compatible on 850 and 1900 MHz bands" which is supported by the note 3, I just dont get why both my unlocked exynos note 2 (got rid of it 1 month after I bought it because of this problem) and also the exynos note 3 have this problem on bell mobility in canada.....

You can always edit data retry to a smaller number in your build.prop.
"ro.telephony.default_network" is the build.prop entry for which default network you're on. You could figure out which one of those corresponds to HSPA+ (probably through trial and error).
**edit
Oh, you may just have to flash a new modem then O.0
My N9005 is missing quite a few radios at the moment as well.

Wish I could do all of that lol

Maybe there is sime kind of problem with your sim and/or phone...
I'm with Virgin (owned by Bell and same network). My device is switching between 3G and HSPA+... And it's working perfectly fine.

SM-N910H the 3g variant

How can i enable LTE on the 3g variant is there a way to enable lte as far as i know it uses the same chipset as sm-n910c
Sent from my SM-N910H using XDA Free mobile app

It uses the same CPU as the N910C, but I doubt the Modem is the same, meaning it may never do LTE.
I could be wrong, and for your sake I hope I am.

Hi i have done that code in app info and there it show the lte band and in the settings it show the option to choose lte/cdma/gsm and it is tickable but when it is choosen when i am in an area of 4g reception i lose signal. I think there should be something to be enabled. Or maybe there is away to enable different lte band because band 5 and 7 are not enabled

When i reach this page i dont have the option to change band or to save the configuration. I will upload my page later on
