Can't get AT&T 3G?

I managed to unlock my Vibrant, but I can't seem to get AT&T 3G on it. Do I need to change done settings to get it to work?
Its only works where AT&T only runs its 1900 MHz band but AT&T mostly runs 850 MHz which the Samsung vibrant does not have. I think the original Samsung galaxy s has it but not us.

Check the bands for this and the att version of the galaxy the ones that are the same are the ones that yours will work on, seems like it would have been easier to get the att galaxy s
You can get 3g by ATT if it is there (available)
This is where you got to go to nmodify the bands and force the phone to recognize. I have used this in Hawaii so, I know it does work. You have to lock the band that is sending the 3g. The Vibrant has Quad band so you just need to know which one is the one they are using.
Okay…so do at your own risk. You can go back and set the phone to its default automatic gsm/cdma settings.
Dial: *#*#197328640#*#*
Click [1] debug screen
Click [8] phone control
Click [7] network control
Click [2] band selection
This is where you make a change, default setting is [1] automatic, which means it chooses automatically between gsm/cdma (Edge vs 3g). So we are going to change this and set it to wcdma band which is 3g.
Click [2] wcdma band
Click [1] wcdma all []
Now it should display “select wcdma all bands [*]"
Now on the bottom of your phone, click the menu key, it’s the one next to the home key, now click back, menu again one more time, back one more time, this is just to confirm it set to number 2 wcdma band.
Now click menu key one last time, click end.. and you are done. Now to double verify that the phone is locked into 3g, dial in: *#*#4636#*#*
Then click phone information Then scroll down to “set preferred network type” It should now have listed “wcdma only.” PS, if you tried to do a shortcut, and just set wcdma this way first without doing the lock above, it would just go back to gsm/cdma auto once you exit the screen.
Good luck

That is my understanding as well. The FCC reports shows AWS and 1900MHz. No 850MHz.

Pretty sure 1900MHz AT&T 3G worked automatically once I unlocked the phone.

[Q] How to set 3g network as default, and permanently disable Data Guard

HI Folks!
I am wondering if someone knows How to set The Network mode to GSM/UMTS?
Navigating the phone tree:
Settings ---> Wireless & Network Settings --> Mobile Networks ---> Network Mode-->
Option Available:
Sprint Only!
Any CDMA!
Any GSM/UMTS
Automatic!
NO matter if I change it or not always when I reboot my phone it goes to CDMA or Automatic but always looks for CDMA.
I am using the photon with UMTS 850mzh so I need to know how to set that by default or how to hold that setting in the phone.
Also I would like to permantly Disable the "Roaming Guards" I am tire of switch off those thing everytime I reset the phone!
Thanks a lot!
p.d phone rooted and Activation thing disabled.
BOMB! bomb!
Set GSM UMTS
Dial *#*#4636#*#* -> Phone Information and select GSM auto (PRL)
Menu>settings>wireless&networks>mobile networks>roaming guards and clear the appropriate check boxes and that should solve your issue.
I'm a MoPho-er

APN settings option

Guys i am having a problem finding the apn options on my sprint lg, The phone is unlocked for any sim, but im trying to get my 3g to work on this phone but is this option even Available?
It is under Settings / More / Mobile Networks
Then choose Network Mode
I guess if you just select CDMA, you will be forced into 3g only.

Stuck at EDGE speeds i545 GSM overseas

I am using my i545 overseas, with a non - Verizon SIM card. I am stuck on EDGE speeds. I don't want LTE, just 3G and UMTS.
Apart from the speed, the phone works perfect, phone calls are OK, internet works (@ low speeds). My local carrier has the same bands in 3G and UMTS as AT&T, so it's 850/1900, and I know the i545 works with that bands.
I am on Stock Android 5.0.1 Baseband I545VRUGOC1 and have root access and hidden menus enabled.
Am I missing something here? Need help, as EDGE speeds are too low for me. Just to be clear, this is not a "low reception zone" or anything like that.
Looking forward to your help.
Nevermind, solved it with the engineering menu: *#27663368378#

Yes, of course.
1-. First you have to enable hidden menus:
-. Change the contents of /efs/carrier/HiddenMenu from OFF to ON (you have to do this by open it and edit it)
-. Save
-.Reboot
2-. Enter engineering menu dialing *#27663368378#
3-. Then go:
[1] UMTS --> [1] DEBUG SCREEN --> [6] PHONE CONTROL --> [7] NETWORK CONTROL --> [2] BAND SELECTION --> [2] WCDMA Band Preference --> [6] WCDMA ALL
After selecting that, phone will connect to selected WCDMA Bands.
I think you DON'T need to be rooted to do this, but it always helps.

[Honor 9N] How to enable LTE only option in settings.

Honor 9N is a latest budget phone from Huawei Honor.
For Indian customers, it comes with network settings as 4 options ( LTE/WCDMA/GSM Auto), (WCDMA, GSM Auto), (WCDMA only) and (GSM only).
While the network signal is weak we don't get LTE band as it jumps down to the lower signal WCDMA or GSM.
Here I will explain how to enable LTE only option in settings.
Steps:
Download the app : Settings database editor
Scroll down and look for "hw_networkmode_preference" and change its value from "9,3,2,1" to "9,3,2,1,11". save it.
Then restart your device.
Now the LTE only option will be available in Settings > Mobile Network.
Remember one thing : You will no longer receive or make a call when you are in LTE only signal. It's because only Jio supports 4G calls (VoLTE).
If you are using any other Network Service like Vodafone In, Idea... Etc, use LTE only option only when it's needed and change into ( LTE/WCDMA/GSM Auto) later to receive calls.
Thanks.:victory:
Screen shot from my Honor 9N.
Values : 9,3,2,1,11,12
Gives :
LTE/WCDMA/GSM Auto
WCDMA/GSM Auto
WCDMA Only
GSM Only
LTE Only
LTE/WCDMA Auto
Changing LTE bands
I bought Honor 9N in India. To my disappointment, I cannot use it with T-Mobile in the U.S. Is there any way to change it? (Full confession: My knowledge of software/hardware is pretty poor)
