Hi,
I saw that some Samsung phones (Note, Note 2, S2 LTE, S2 HD LTE) can enable AWS frequency.
Can the same be done for S3 i9300?
thanks in advance,
*#197328640# or *#*#197328640#*#*
[1] Debug Screen -> [8] Phone Control -> [7] Network Control -> [2] Band Selection -> [4] Combi Bands = Tick option [7] WCDMA 1700 (FDD IV)
if u see the asterisc beside that option the frecuency it's enabled..
There was no asterisk on that band, I enabled it so the asterisk showed up.
I rebooted the phone and the asterisk was still there.
However, it doesnt seem to help, the sim card still doesnt register on the network
maybe post in the correct section?

What would the correct section be for this kind of question, of not Q&A, Help & Troubleshooting ?

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.

It is trivial, of course I was check this partition of settings first of all. No, problem with detect of network with different SIM.
Clarification: radio band was changing via *#*#4636#*#* I think that radio band was change frequences and I am shure it can be changing manually by two clicks, but where...
i do the same and have to fully reflash with latest sbf to fix problem.
i broke my band with creating activity shortcut on the desktop with launcher pro, push it and select usa band
There must be a way
Please help
Explain more. More details.

There isn't. Its a hardware "problem". It isn't a real problem as the I9300 isn't made for USs T-Mobile bands
Sent from my SGH-I897 using xda premium
not sure if it would work but you could try to fix the phone's frequency to 1700?
for that dial: *#197328640# => Debug Screen => Phone Control => Network Control => Band Selection
I may be wrong as I do not know US T-Mobile's standards.

I am using that code all the time to fix my S3 to the frequency over here in Thailand.
Just tested again " *#197328640# " (without the ") and it works fine.
While messing with the setting in the hidden Menu.
I unlock the T-Mobile LTE Network on My US Cellular GS3
Internet: T-Mobile US LTE
Band: LTE:14
Data Speeds 20mbps down 3.6 mbps up
Mms: Works Flawless
Now My Problem. i cant make a phone call or receive a phone call
My Setting
Hidden Menu: *#22745927
enable hidden menu
*#197328640#
[1] UMTS > DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL > BAND SELECTION to set GSM Band preference
[2] CDMA > COMMON > NEXT PAGE > NEXT PAGE > PREF MODE SET to select GSM/WCDMA ONLY
SIM>TEST CSIM
WAIT 90 SECONDS THE REBOOT
VOILA! TMOBILE LTE.
Now i have succesfully unlock The Verison GS3 to Tmobile on Edge is there a way to port that radio. to get cell connectivity.
or if anyone want to try to tweak these settings to get more than just LTE connection. or get Voice over LTE working!
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#

Hello could you explain more precisely how you did to make it work. Thanks

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.
