For some reason the galaxy s2 is only on Edge, i never see 3g or the H
The baseband is galaxy s2 baseband I9100XXKH3
Is this the problem? i know i should have 3g in my area but when i check "about" it only shows edge
Whats wrong with the phone?
Thanks for anyone that can help
Two things to check would be to see if your provider supports the 3G band that the phone supports and also to see if your Wireless Network settings are set properly. You can choose auto to select both bands or select GSM only.
Then, try changing radios.
If your sim is old get a new one. Just ask your carrier you should get one for free. The old sims don't support UMTS.

Hi guys.
I didn't know where to post and I have few questions on my Galaxy SII I bought from Korea and brought to USA.
I have KT's 250S galaxy SII and I'm trying to use it for At&t. I tried to put my At&t sim card in and looks like it is getting some connection. I was able to make a call.
However, looks like it's not getting any 3G connections. I heard there is some modification on the network I need to change to get 3G. Could you please let me know what should I do?
Thank you,
Andy

Go to the miui thread in development section and use the apn from there. That should theoretically fix your issue...

From the third post down:
Code:
<< Korea Galaxy S2 Network support >>
Double band UMTS 900/2100
Triple band GSM 900/1800/1900
<< EU Galaxy S2 band Network support>>
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
AT&T and International (I9100) GSIIs support the same bands, which is why I9100s work perfectly in the US. Your device is completely missing support for the 850 MHz band (first device I've seen in years that wasn't quadband GSM other than dumbphones) and also missing support for 3G in the 1800 MHz band.
So you will not have 3G coverage anywhere, and you will completely lose coverage where AT&T uses the 850 MHz band.
Hello,
I have the international phone of the S2. I am right now running on T-Mobile's service. I can call, sms, and mms just fine. But its on the EDGE network for data. If you root the phone (which I have done before), will I be able to force the phone to go into a 4G network like HSPDA? T-Mobile is a GSM network, however T-Mobile's required bands (1700 and 2100) are not listed in the GSM bands but on the HSPDA bands.
You can force the use of WCDMA without root access by dialing *#*#4636#*#* selecting phone information and then WCDMA only from the drop down box.

I selected WCDMA only, but for some reason, it automatically switches back to auto mode. Should I reflash the modem?
Umust have selected Preffered... Use WCDMA only
Peace
Hit Thanks & It will Disappear

even if you force the phoone to use UMTS, or HSDPA, you probably still won't see 3G (or what t-mobile call 4G), until they refarm their 3G network to 1900 band in your market (or you could be one of the lucky few that are in those refarmed market already).

If you are using the international variant of Galaxy SII, ie GT I9100, on T-Mobile, don't even bother yourself as you will be stucked on EDGE.

Hi,
I have Galaxy ZOOM LTE (SM-C105) (not SM-101)
I have similar problem to Galaxy S4 (GT-i9505) owners - no LTE option in phone menu.
I'm 100% sure than phone have LTE because I can install app "Advanced Signal Status " and LTE works.
I flashed with diferemt ROM (oryginal) but nothing happened.
What else can I do?

Got the same problem... anyone can help?

i have the same problem,
im with 3 uk, and its not giving me LTE and its not in the settings to select.
but i tried an EE sim (in an EE shop) and YES it connected to LTE and i see the LTE option in the settings..
looking at the wiki/List_of_LTE_networks#Europe
i see this..
3UK for LTE uses
Frequency 800 MHz Band 20 and 1800 MHz Band 3
EE for LTE uses
Frequency 2600 MHz Band 7 and 1800 MHz Band 3
now i know my zoom SM-C105 Flashed with the factory unbranded UK firmware CAN connect to LTE
what do you think is my next move?
could i try flashing with a Switzerland firmware that i see also uses Frequency 2600 MHz Band 7
or am i heading down the wrong path?
---------- Post added at 08:45 PM ---------- Previous post was at 08:41 PM ----------
Is there a 3UK official firmware out there i could try?
and if i found one, would flashing it lock my sp-unlocked phone to 3UK?
useing the app PHONE INFO SAMSUNG i get this...
so, the app tells me under heading 'Orignal csc code: = BTU that we know is UK & IRE (dose the app get this from the hardware?)
and the app says under the heading 'Firmware info:
bootloder c105xxuana1
baseband c105xxuana1
pda c105xxuana1
csc c105BTUuana1 <--- notice the BTU
under os
build number, fingerprint and build dicription all have c105xxuana1 in the text...
we know c105xxuana1 refers to newzeeland and they dont use the 800Mhz band 20 that i appear to need.
so it appears i have UK hardware running Newzeeland Firmware
ideas?
ok more info...
just checking samsung site and this SM-C105 can defiantly do 4G (LTE): 800/850/900/1,800/2,100/2,600MHz
both 3uk and EE use 1800 and as i cant connect to LTE with the 3UK sim, lets put the 1800 to one side....
with the EE sim in, it DID connect to LTE so i guess it used the 2600 band.
only bad left that 3UK use is the 800 band, so ive just flashed the UK Voda FW that ONLY uses the 800 band for LTE
ive a feeing im getting closer but in settings i still dont see LTE
only this...
WCDMA/GSM (auto connect)
WCDMA only
GSM only
im not currently in an LTE signal place so cant test this, but would the option LTE/WCDMA/GSM (auto connect)
only show up when in an LTE area?
Posting this and hopefully helping others.
Yesssssss got 4G today on my trip to london..
not sure if its one of these three things below or a combination of two or all three as i did this steps in a non 4g place and couldn't test for a few days.
1. i flashed the UK Voda software, according to the LTE wiki vodaphone uk only uses the 800mhz band for LTE.
2. installed the app 'Advanced Singnal Status'
3. got a replacement simcard from the 3uk shop. (instant transfer of number to new sim no pac required)
in the 'Advanced Singnal Status' app, tap ADDITIONAL INFO, (on the other firmwares i tried it wouldnt let me in this section, says locked out or words to that effect)
in additional info, tap Device Information. and then i Set 'Preferred Network Type' to 'LTE/GSM auto (PRL)' then hit home to back out.
(NOTE: in the phones Settings > More Networks > Mobile Networks > Network Mode.. there still ISNT an LTE option, even when i was connected to 4G today.)
ive a feeling i would still have to use the toggle in Advanced Signal Status app after a reboot, as LTE still isn't showing up in the phones settings menu.
But ether way im happy. spent most of the day driving so didnt get to test out the 4G but google maps was streaming and my radio app was streaming
lovley, with a sexy 4G logo where i normally only see H+
I have a I9300 S3 international version. I recently Shifted to the US and am not able to get 3G connectivity. I can see only EDGE network. I know its got something to do with frequencies, because I have the APN etc correctly set up. My only question is will it ever work on 3G on T-Mobile? Is it fixable by flashing any modem?
P.S. I'm using Cyanogenmod 4.4.4.
While I was working in Korea, I bought a Galaxy s3 SHV-E210 (Korean Model) cell phone. When I bought, I was told that I would be able to use it over here in the States. AT&T was able to put a sim card and activate it on their network, however I only get 3G. The Sales rep told me that the bands for 4G/LTE are different in Korea than stateside carriers, so I may, or may not pick up 4G/LTE. I've done some research and found that the band in the phone can be changed using certain codes. When I enter *#9090# it brings up a menu, I've tried changing some of the 4G/LTE, 3G options in that menu but I never get 4G. I know how to root and put custom firmware on devices, so if that is something I need to do then I am comfortable with that. Can this phone be changed to get a 4G/LTE signal? are there any more "codes" that I can enter in to get any other options that will help me? has anyone here ever change the band on their phone to work on 4g? Thank you for any and all help.
AT&T uses LTE band 1 for service.
since E210S only supports band 3 and 5, and 3 and 8 for E210K, there's no way to access AT&T LTE network with your device.
It is reported to support band 1 for newer devices like S5 and G3 and AT&T LTE devices might work in Korea since May 2014,
LTE won't be available with Korean S3 in US.
