Over in this thread in the GalaxyS forums, they have found a Debug menu which allows users to enable hitherto hidden bands on their international GalaxyS devices. Specifically, the 850mhz 3g band.
I tested this on my US T-Mobile Vibrant. We found that the Vibrant - although a T-Mobile phone - supports the 850 AND 1900 UMTS/WCDMA bands. No other T-Mobile phones supports 1900 or 850 UMTS, so it looks like Samsung is using the same internal hardware on almost every galaxyS.
So if they are using identical hardware, i'm curious if the Captivate actually supports the 1700/AWS band used by T-Mobile USA, and Wind Canada.
Can a nice user go through their menus and help me out?
Do this:
1. on the phone dialer keypad, type *#*#197328640#*#*
2. Select [1] Debug Screen
3. Select [8] Phone control
4. Select [7] Network control
5. Select [2] Band Selection
6. Select [4] Combi Bands []
You should see a list of supported bands for GSM and UMTS (WCDMA). Can anyone say if the Captivate also supports 1700?
No. [2] Is band selection, not network selection. And when I pressed it, I got an error "RAT Selections Option is Restricted!"

I wonder why you were allowed into that menu but I was denied it. I got an message about RAT settings not being allowed to be changed.
I have seen in the captivate Dev section threads about fixing 3G by updating to the I9000 Modem firmware or something like that
Does anyone think this would also allow TMO to get 3G on the captivate or perhaps installing the vibrants modem firmware???????

I'd say probably not.
I would imagine that the hardware (antenna) is missing for those frequencies. We had the same questions for the i8910 when it was released.. would it work in N/A on 3G? The answer was no.
The explaination is that the phones run the same base firmware, but some hardware in not available to some of the software options in the firmware, hence access denied, loss of connectivity or simply no message.
I have:

There is no 'Band Selection' menu at all for me.
According to the fcc the captivate does not support aws and the vibrant supports only the 1900 band not the 850.

I would bet the physical radio and antenna are both there but simply disabled somehow. We have the FM receiver that is disabled but it's still there. If I had to guess, the Vibrant, Captivate and I9000 are probably all physically the same.
I know HTC makes some of their devices for all supported frequencies and then they selectively disable the one's not supported/wanted for a specific carrier.

I also got this on my captivate, however it worked just fine on my vibrant.
over at the main SGS forum
we already did the test, our phones are hardware band locked, it's not a software thing
we tried flashing a 850/1900/2100 to a UK phone, and a 900/1900/2100 to a US phone, and although everything works, you still do not get the radio band as the actual hardware is not there
so even if you flash a 1700/1900/2100 from USA vibrant onto the Canada vibrant it will not pickup the 1700/2100 band because the hardware is not there, even though there are network that runs at 1700 here.

Go to Start>Settings>Phone>More.
First one should be band selection. Highlight it and press Get settings.
You will be able to select the frequency band.
- Automatic
- GSM 900 / 1800
- GSM 1900
- WCDMA
Select either GSM 900 / 1800 OR GSM 1900 depending on your network carrier.
Last, RTFM.
thx !!
I'm going to buy i780 and just want to make sure I can log into 2G band, 'cos the signal of local 3G provider is really suxk. And FYI, I RTFM already, but it never mentioning the band locking/choosing.....
I have an unlocked touch cruise with t-mobile in the us, but don’t understand how, or if I can, use the 3g function for internet data access. My questions are as follows:
1. How do I find out if my phone is the European version or the US version (each has differing specs on accessing the 3g network).
2. If it is the US version, will I be able to access the 3g network on t-mobile or AT&T in the US?
3. If it is the European version, will I be able to access the 3g network.
4. How do I know whether my phone is accessing 3g or not?
5. Is there a software fix to allow me to use either the European version or us version to access 3G.
Thanks in advance for any help you can offer.
Dave
there's only one version of the Cruise out:
http://www.htc.com/www/product.aspx?id=798
These are the frequencies:
Network HSDPA/UMTS: 2100 MHz (Europe), 850/1900 MHz (USA)
HSDPA: Up to 384kbps for upload and 3.6Mbps for download
UMTS: Up to 384kbps for upload and download
GSM/GPRS/EDGE: Quad-band 850, 900, 1800, and 1900 MHz (The device will operate on frequencies available from the cellular network)
It's triband 3G. It is currently working on ATT 3G in the US. I don't know about TMobile is there 3G network up and running, and if so I don't remember what frequency that might be at.
The icons at the top point to what type of network E/G is Edge, while 3G/H is 3G.
You can go into the Phone Settings under Band and see some of the different frequency choices. You can force it to be on Edge/GSM there or Auto (which will pick up 3G if it's available).

As I understand it (for internet data access) the european version (as alluded to in your quote) works at Network frequency: HSDPA/UMTS: 2100 MHz (Europe), the American version at the frequencies: 850/1900 MHz (USA). If my phone is the european version, then it works at 2100, and will not access usa networks, unless there is a fix.
t-mobile is 3G in my area.
How to I access the "phone settings under band". I cannot find this on my phone.
Thanks
What I am saying is the device can function on all 3 frequencies listed on the specifications page. I believe the Tmobile 3G frequencies are 1700/2100. You might want to search on the forum and check it out for sure. If it is 1700 you are out of luck. Here are some threads discussing it.

hmmm, htc told me there were two versions that the european version does not have the capability to switch to the us frequencies, which the specs list as 850 / 1900, but is only using the 2100 frequency. I'm not sure htc tech support is always accurate.
However when I go to the band tab via comm manager, settings, phone, band, it shows me (found with your assistance) that I can select gsm (1900 + 850) + UMTS(1900+850). I assume I should use this setting rather then auto.
T-mobile claims they use the 1900 and 850 bands. I am still at Edge.
I have not had time to read the threads you listed, and will do that later today. Perhaps I will have more questions then, but for now, did I select the correct gsm settings?
Thanks,
Dave
3g access
ok, read the posts you mentioned.
More information about differing versions
from phonescoop.com:
Versions of touch cruise for different regions support different 3G frequency bands.Eurasian version is WCDMA 2100 only)
I assume that since the 850 and 1900 is listed in my setup program, I have the usa version, if phonescoop is correct about two versions.
Since t-mobile works on 1700 I assume I cannot have 3g with them.
Will I get 3g with AT&T?
i personally have never heard of 2 different versions of the Cruise. I have one presumably imported from the UK and works on 3G here.
Btw the Cruise manual says this:
FunctionalityHSDPA/UMTS: 2100MHz for Europe, 850/1900MHz for USA HSDPA: Up to 384kbps for upload and 3.6Mbps for download UMTS: Up to 384kbps for upload and download
GSM/GPRS/EDGE: Quad-band (850, 900, 1800, and 1900)
There is only one version of the Cruise.
Also a caveat about the bands available in the Band tab of the Phone Settings. I believe some options might be available in the drop down even though the phone doesn't support it. Best thing is to look at the phone specs.

Bodison,
My phone has the same features in your picture.
1. Hambola states
"Also a caveat about the bands available in the Band tab of the Phone Settings. I believe some options might be available in the drop down even though the phone doesn't support it. Best thing is to look at the phone specs."
suggesting what's in the picture may not be in the phone.
2. He also states:
a.
"FunctionalityHSDPA/UMTS: 2100MHz for Europe, 850/1900MHz for USA HSDPA: Up to 384kbps for upload and 3.6Mbps for download UMTS: Up to 384kbps for upload and download
GSM/GPRS/EDGE: Quad-band (850, 900, 1800, and 1900)
b.There is only one version of the Cruise."
The phone specs restate what he states in 2a.
A and B seem to contradict one another. Unless it means that the phone is capable of all the MHz frequencies mentioned (850, 1900, and 2100), and when used in Europe it accesses 2100 frequency, and in the US the other frequency. This is not clearly stated in the specs.
If the allusion to functionality does not mean that the frequency used depends on where the phone is used, then therefore there are two versions, with hsdpa/umts for europe (2100) and another for USA (850/1900). In any case, HTC (probably not the ulimate source of reliability) states that there are indeed two versions.
According to Hambola's reference to the caution that what is in the picture may not be in the phone, what is in the picture shows what is in the specs of the phone. He is therefore suggesting that what is in the specs of the phone (as shown in the picture) are not reliable. Not sure what the implications of this are.
I have been reading other posts about 3g with ATT. Is it safe to assume that (if there is one version of the phone, or I have the one that is able to access the US bands as shown in Bodison's picture), that I will be smokin when I switch to ATT in January when my contract runs out?
I am pretty sure there is only one version of the Cruise and it has those 3 bands listed for 3G. In fact there are guys on this forum that have the UK Orbit O2 running on the ATT 3G stateside.

In any case, I tested my phone with a buddy's ATT sim card and was able to access 3G for browsing just fine.

Hi
I was told this would be a better forum for this question.
I have a huawei ideos (older non X6 version) and supposedly it is unlocked. It works with 2g/edge. It does not work with t-mobile 3g. I have looked for APN information and the info downloaded to the phone when I connected to t-mobile network is identical to what is listed on the net.
ie. I added
MMSC: http<colon><twoslash>mms.msg.eng.t-mobile.com/mms/wapenc
xxx added because I can not post urls.
Things which are odd. When choosing access network, it does not say T-mobile 3G. It only says T-mobile 2g, Att 2g and Att 3g. According to the net this phone supports the frequencies for tmobile.
gsm link for u8150 not allowed.
shows HSDPA 900 / 2100 / AWS
HSDPA 850 / 1900 / 2100 / 1700
And the wikipedia entry for tmobile
shows
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31]) 2006 2008 (3G), 2010 (Marketed as 4G) First carrier in the U.S. to deploy services on AWS frequencies. Markets HSPA+ as "4G". UMTS band IV
Not sure if HSPDA spec is same as HSPA though.
I did the trick where you enter #*#*4636*#*#* and checked phone settings. I changed the setting from CDMA to GSM auto (PRL). I also tried to hit menu and select radio band, but it pulls up an empty "Set GSM/UMTS Band" dialog. There is nothing to select.
I guess my question is, does this phone support 3G for t-mobile and if so, what setting am I missing?
thanks in advance.

I got an email from Huawei support
Hi,
Just as another data point. I got an email regarding this issue from Huawei support. They said an unlocked phone from one provider may not fully support 3g on T-Mobile. I asked them what he meant by not fully support.
Here is an excerpt from the Huawei email:
This phone is capable to be used in 3G that is correct, however if the phone is unlocked from the original provider it may not be fully compatible on 3G on the different providers network.

Moving to Q&A
three more datapoints
Hi
I got another note from Huawei. They said they don't support unlocked phones.
I talked to t-mobile support. They said the u8150 uses PPP and not RMNET. I have never heard of RMNET, and that the phone would only support 3G if it was rooted.
This seem like BS all around to me. T-mobile and Huawei.
I did test my phone with a friends tmobile sim and the phone behaved the same. ie. edge only.
Some more datapoints
Hi
This phone is available in two different frequency capabilities. Considering mine can see the ATT 3G network, it must be using the second set of frequencies. This second set is listed as usable by T-Mobile as well. Here is the info:
From the huawei spec sheet.
At the top it shows
UMTS 900/AWS/2100MHz or
UMTS 850/1700/1900/2100MHz;
EDGE/GSM/GPRS: 850/900/1800/1900MHz
According to Wikipedia
ATT
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/HSPA 3G
1900 MHz UMTS/HSPA 3G
700 MHz LTE 4G
T-Mobile
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz/2100 MHz UMTS (W-CDMA)/HSPA 4G (formerly 3G[31])
When I connect to wireless networks, I see three choices:
T-Mobile 2G
AT&T 2G
AT&T 3G
So I am guessing my u8150 is using the second UMTS set of frequencies:
1. 850 (since it sees two edge networks and that is only available in the second set.)
2. 850 and 1900 (since it see's AT&T 3G and it is also in the second set)
This second set of frequencies is also used by T-Mobile so I don't understand why this phone can not connect to T-Mobile 3G using my simcard or my pals.
It's all about the supported 3/4g bands. Most carrier Androids only support their networks spectrum's. Check gsmarena to ensure compatibility.
Hi,
Thanks for the info. Maybe I don't understand, but I thought gsmarena showed this phone as using both the Att and Tmobile bands. I remember when I had nexus ones was that one version was for ATT 3G and one was for TMobile 3G. I'm guessing that the 8150 is similar with the exception that huawei has not published accurate docs. ie. their docs say both frequences for all phones when in reality its two different model phones with only one label.

I apologize for not reading all of your posts
This isn't BS. It's the same issue facing Cricket phones attempting to connect on Verizon. I'm not fully up to speed but it looks like RMNET needs to be added via the kernel (edit sources and compile).
The below thread isn't specific to Tmo but it should give you some insight.
[04JAN][TMOUS]CMYLXGO's Stripped & Squashed Stock Desire HD[KERNEL:gauner1986][RMNET]
This is what Huawei meant by "may not be supported". However, if the phone connected to Tmo with SIM then it's already carrier unlocked. You now face the above issue plus prl, etc.
You face a long road ahead. My suggestion, sell the Huawei and buy a used Tmo Android.
Hi! I've bought this phone (SGH-T959V) from T-Mobile on USA, and when I went to Argentina, I found that the carrier that I have (Movistar) mixes the frequencies or something like that.
It uses GSM 850 / 1900 and UMTS 850 / 1900. By default, my phone can't use 3g (neither HSDPA) from this carrier.
Dialing *#*#197328640#*#* And going to Network Control > Band Selection, I can choose which frequencies to enable / disable.
If I disable GSM 850, and enable all the rest, I can get to use 3g on the 1900 Mhz, but I get much lower signal.
The frequencies that I can enable / disable from this menu are:
GSM 850
GSM 900
FCS 1800
PCS 1900
WCDMA 2100
WCDMA 1700
WCDMA 1900
I don't know how this works, I want to use my phone and be able to use 3g / HSDPA / HSDPA+ / 4g if possible..
I think that I need to find a way to enable WCDMA 850 on my phone.. Is it possible?
I am using the last upgrade from Kies (Gingerbread) 2.3.6
Do I have to flash a new modem? I've searched for available modems for this phone, but none of them say anything about enabling WCDMA 850 frequency
When I go into Settings - Wireless and network - Mobile networks - Network mode it has a GSM/WCDMA (auto mode)
Have you tried that?
Yes, I've tried that, that option is enabled!
In the GL9003L model (Samsung Galaxy S too) from this country, the WCDMA 850 option is enable (also the WCDMA900). Isn't there a way to add that frequency to my phone >.< ?
The hardware doesn't support UMTS 850 which you said is used by your carrier's 4G. You won't be able to use this phone on their 4G network.
Buh, so there's no way to change the frequencies it uses?
Sucks I can't use 3g (not 4g, 3g!!!) on my country
No you won't be able to. According to this page, these are the frequencies available on the phone:
http://www.gsmarena.com/samsung_galaxy_s_4g-3719.php
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
Click to expand...
Click to collapse
Your network will have to be running on exactly those frequenices to get 3G/4G
I think that is wrong.. I have another carrier that works on the 850 / 1900 band and I CAN user their 3g (mostly because I can connect to the 1900 band..), but I can't use HSDPA+.
So:
with one carrier, Movistar, that uses UMTS 850 / 1900 I can't use 3g, it only connects to the EDGE network, and when I dial *#0011# with the GSM bands disabled it says that the 3g service is limited and I can't use it at all.
With the other carrier, Personal, that uses the same bands, I can use 3g on the 1900 band, but can't use HSDPA or the 850 band.
Also, from the #*#*193728640#*#* menu I can choose the UMTS 1900 band.
I've a similar problem the difference is a got 3G but not 4G and can't figure out what is going on. I'm with digicel and the only use 1900 wich is already enabled. I once tried movistar and had the same problem I suggest you another carrier
This's my problem:

Do not trust phonearena as it has wrong information about our device frequencies that it can use.
umts 1700,2100,1900
So basically no, you won't get anything else than edge on those 850/900 frequencies.
Sent from my SGH-T959V using XDA App
So i just bought a LG G PRO 2 checked it everything seemed to work fine
But then i realized the network connection drops every few mins and reconnects only to a G signal (2G)
so upon further investigation i discover that the band frequency on this model is CDMA eg. USA + Canada
To say im P*&^ed off is an understatement clearly the person who sold me this is aware and is now ignoring any contact i try to make with him
I have contacted LG to see if i can possible purchase a motherboard for model D837 or D838 as i see this is my only option to get the device working
Unless anyone here can advise otherwise
Once i go into the band selection screen and disable CDMA bands it seems to sustain a stable connection but only to a 2G network haven't been into a 4G area as of yet to test but it is completely incapable of connection to a 3G frequency within the uk which i will be connected to 80% of the time
not 100% with the F350 but the frequencies for it should be:
2G: GSM 850 / 900 / 1800 / 1900 MHz
3G: UMTS 2100 MHz
4G: LTE 850 / 1800 MHz
2G is fine, as UK uses 900/1800.
3G: all UK networks at 2100.
4G: only EE/3 use the 1800MHz frequency. no-one uses 850 in UK.
look around the forum for the secret menu and see if you need to enable 3G/4G manually. or do a manual firmware update.
,My Wife has an F320S (G2)and she can enable all Bands in the Hidden Menu and works fine in Europe in Austria.Network Operator is Three (HG3).
I think the F350S is the same.
Go to Dialer and tipe 5457#*350#
in Modem Settings can you aktivate all Bands what you need
I hope this works for you.
Thanks for the reply guys
There's loads of settings in the hidden menu
I cant see how changing anything in here will help as it is a CDMA device which means it physically does not have the necessary hardware to connect to a 3G network in the UK
As it uses a totally different technology than UMTS
Ive discovered at WCDMA is actually UMTS so i cant see why it doesn't work ?

Clearly the problem is the WCDMA bands on the device are 850 / 1900 / 2100 while 2100 is used here 900 is the more widely available and thus incompatible with device
I think my only option is to sell it on but to who its no use to anyone in the UK really
