Hi All,
Currently released version of Samsung Omnia i900 does not support UMTS 850/1900, which are north american 3G frequencies, according to official Samsung documentation, as well as FCC approval docs. However it has been recently established the radio chip does support those frequencies, and they are locked in the firmware only. Here is the evidence to support this claim:
This is the official FCC documentation for i900 certification:
https://fjallfoss.fcc.gov/oetcf/eas...me=N&application_id=476604&fcc_id='A3LSGHI900
On the page 4 of the "Internal Photos" document you can clearly identify the radio chip - it's Qualcomm RTR6285 and according to Qualcomm:
"Support for Eight UMTS Bands, Four EGPRS Bands, Triple-Band Receive Diversity and GPS Integrated into Power-Optimized RTR6285 Device": http://www.qualcomm.com/news/releases/2006/060213_worlds_first_single.html
So, it's only as matter of unlocking those frequencies in the current firmware. Samsung made our job a little easier, by recently making a public release of new ROM with updated firmware, so we won't have to dump it ourselves: http://www.samsungmobile.com/promotion/omnia/sg/sub02_xp.jsp#
I have limited free time and limited experience with reversing PDA firmware, to be able to achieve this by myself - please help.
I just got an Omnia and sometimes it hits the 3g network so i am sure that the firmware is there but it is locked.

more details please - where are you at? what network/carrier do you mean? do you really see 3G icon and experience fast browsing/download? what is the firmware version on your Omnia? (Settings -> System ->Version)
AT&T.I have it from Singapore.PDA:i900DXHH3/DZHH3.As i mentioned it hits 3g for a minute or so and then it goes back to edge
man i sure hope this issue gets fixed!

a US model for the Samsung Omnia is coming to the US in October via AT&T. Look for the Samsung Mirage.

AllTheWay I started this thread to solve the problem for people in US,who already have Singapore/European Omnia, the i900. It's a well known fact Mirage hits AT&T on October 21st, but it doesn't help us one bit. Unless of course, you're willing to dump the ROM from i907, reverse it and replace the i900's radio with the one from i907 with all supported UMTS frequencies unlocked
I wish somebody could help us out on this issue, I dont know enough about rom editing to be of use ;(
besides, i think the 907 is already available but not branded to at&t: http://www.celluloco.com/samsung-i907-omnia-8gb-us-3g-support-version-hsdpa850-1900-e-pr-1873.html
any update of this thread?
HTC Diamond users with US 3G - please help
I'm starting to believe it might actually be possible to tweak existing radio firmware to unlock UMTS 850/1900Mhz bands using already embedded secret debug menu from Samsung developers, rather than having to dump it, reverse it, patch and flash back. Here is the secret code to access Root Debug Menu on Omnia: *#197328640#
Option #4 "UMTS rf nv" has sub-option "umts rf nv write", which I think allows to modify the active UMTS bands in the radio. Assuming we have that set correctly, option #9 "Common" from the same Root Debug Menu has sub-option #5 "WCDMA Set Channel", which allows to specify downlink channel range.
Here is my idea: some devices, such as HTC Diamond with US 3G enabled radio, have the same Qualcomm chip as Omnia, and run the same WM 6.1 OS. So,
I'm thinking it's worth a shot if someone with US enabled HTC Diamond provided us with settings from his device for those 2 configurable menus I just mentioned. If you backup your own settings, so you could restore them if it doesn't work - I think trying settings from another device will not fry the radio, worst case scenario transceiver will just shut down and be offline until settings are restored.
This would be great.... Iv'e been dieing to get 3g in the usa with the omnia.... Can anyone help with this?
Any updates on this? Would be nice. Especially now since we know omnia isn't coming to ATT as i907
If possible i will donate to the guy that dicover how to enable!
It may be easier to copy the setting from an I907 Epix. That has almost identical hardware and it is ATT + Samsung + Tri Band UMTS.
When I try writing the WCDMA channel it says "That value is wrong".
Also, I can only set one number, so I assume that they want me to set one in the listed range which is WCDMA2100.
Here are the bands:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
Oddly, the Channels currently set stretch a few beyond the range cited on Wiki for WCDMA 2100. They start on the same channel.
Another oddity is that there is no uplink channel. I suppose that people just use Edge for this? Does the I907 do HSUPA?
well...
i'm living in ISRAEL,
and we have GSM network but we also have another cellular company that work with "UMTS 2100/850" band..
i'm working well on 3G with the 2100 band (my onmina have only UMTS/WCDMA 2100 only without 850 also..)
i will be happy to open if it's possible the UMTS/WCDMA 850 also.. so i'll have both 2100 + 850 on WCDM/UMTS (not GSM) freq...
but i'm not shure it's possible to open what ever you like.. anyway i'll try to ask our guys (at my cellular company i'm working at) about this freq stuff...
hope this thread will bring us good information..
also, just know.. my job is with Cellular phones.. and we have "for Testing" Omnia phone with WCDMA/UMTS 2100/850 bands..
but i don't know how i can download the firmware to my pc and try to use it on my omnia back...
if anyone know how i can "take-out" the firmware explane to me and i'll try to do it....
..
Someone else has further evidence:

OK guys,
i had this omnia in my hands..
the Version says
PDA: i900LJJHK1/JJHK1
PHONE: i900LJJHK1
as i think.. it's diffrent model.. I900L this "L" model.. not like ours phones... (i think, it's looks exactly the same!)
i don't think the ROM will chane the bands anyway..
anyway as you asked me to do.. when i'm doing the *#2263# code
i'm getting diffrent menu then our Omnias..
i'm getting 3 options that one of them it's "WCDMA Band Select" and in there you have ALL the UMTS bands and there is "Automatic" option.. what says this phone open to all kind of UMTS networks............ (including GSM also..)

jakeordie said:
juvaknin, you posted this on Modaco as "PHONE: i900JJHK1" without the L. Please let us know which one it was. Thanks!
Click to expand...

yes, it was suppose to be with "L" mabe i forgot it on Modaco forum
anyway i hope this is only Rom issue... but anyway i can't "Rip" the rom right now.. because this phone is 24/7 testing time and i can't "make it gone" from the test station to drop the rom to my PC
i hope there are more guys who have this I900L to share the rom with us..
anyway you remmeber the code that you can change the phone settings buy country?
the main code is (type it from the dailer) *#1546792*#
and the password for section "2 - Preconfiguration" is *#81230*#
it's looks like if we will have the code for the "Internal" section, mabe we will find something in there ?!?!
if we will change to another country.. like Austrlia or something.. the bands will change also? what you guys think?
Hi juvaknin I was reading on web that this i900L is for latinamerica and its frequency was
Cellularhone
Cellular_Networks: GSM850, GSM900, GSM1800, GSM1900, UMTS850, UMTS1900
Cellular-Data;Links: CSD, GPRS, EDGE, UMTS, HSDPA
found this at hxxp://www.pdadb.net/index.php?m=specs&id=1446
change the xx for tt. Also wher did you buy this phone this info is real ?

Hello!
Congrats for this community!
I have a problem and I cannot find the answer on internet:
Can I change the 3g frequency of my LG P705 optimus l7??? How can I test it?
I bought it in China and I'm from Argentina, here the frequencies are 850/1900 MHz, different from the frequencies used in China. I coudn't found information about it! It is factory-unlocked and it has Android 4.0.3 by default.
My cell phone is not usefull without 3g, I can connect to 2g or to Wifi networks but I need faster communications all the time.
Thanks and many thanks!
Diego
same as me but need it for Mexico (telcel) trying to get some different firmware but i'm still not so sure to do this with out knowing all
Hi...
I have Samsung Galaxy S4 LTE which is international version (GT-i9505), my device going mad that just have EDGE connection. I live in Indonesia which dont have LTE access. but my phone can catch any 3G/HSDPA/HSPA network just stuck on EDGE. im also use XL AXIATA provider that provide HSDPA on Band 2100MHZ, i have read all specification of my phone that its have possibilities to access UMTS/HSDPA network. but its nothing with me. i also have other LTE device which is Galaxy Note 4G LTE Korean version. it has HSDPA network and little similar network properties with my S4.
how to make my s4 can access 3G network ???? please help n sorry for my bad english
thanks
Hi people, i want buy a N900T in T-Mobile (used in eBay) to use this in Argentina but in my country don't have 3G signal in all sites. In my city don't have 3G but this have 2G bands. This model have quad band GSM? or only have 3G/4G?
Thanks!!
Hello, I have this same problem, buy N900T [stock n900tuvucnb4] in US, to use in Europe, Poland.
3G band is working, calling and internet, but 2G is not, no signal ;/
I instail custom rom from n9005 [alexndr.n9005xxugng1] and custom kernel [aurora kernel r11].
Phone have 2g signal, is conecting to the carrier but i can't make a phone calls and sms, I dial a numer but noting hapend, no signal.
Any advice ?
Hi, i have in my hands the N900T and works perfect! I don't have 3G in my city and with 2G works perfect! no problems with this. Try flash the modem for this model.
Hello ,
I bought a SM900F from UK a while ago and it was unlocked. I was capable of using 4G network there easily with no problems, but recently I have come to Dubai and am not able to hop on the 4G network . I have checked all the settings and made sure I had the 4G sim/ 4G data bundle and so on , but still same problem.
As per Wiki : Etisalat United Arab Emirates 1800 3 FDD September 2011 [500]
Etisalat United Arab Emirates 2600 7 FDD September 2011 [520]
My operator provides 4G on 1800 and 2600 Frequencies which are supported by SM900F. Just to clarify , this unit had never been locked .
So now im sitting here confused on what I need to do to get my 4G working , Im always connected to H and H+ .
Thanks in Advance ,
Nylem
Try to ask operator to give you his APN settings!
Settings - more networks - mobile networks - ap
Thanks for the reply ,
I have done that but still no hope

Your phone should support those LTE bands.
Confirm that the band /frequency information isn't outdated.
Are you in an area where the carrier doesn't have LTE coverage?
Open a support ticket to investigate if the carrier has provisioned your account /SIM correctly for LTE.
Look at the various online forums and find out if others are getting LTE in your location.
Set what the LTE signal strength is in the S5 service menu.
Set a preference for LTE in the service menu.
Possibly you are getting 4G, bit the onscreen icon is just incorrect?
Try updating or changing your 900F modem.

Thanks for the swift response mate ,
1) Band/Frequency are all compatible with the phone
2) The whole city is LTE covered ( specially mine that I live in the center ) .
3) Already working on a ticket with the carrier , but they say problem is from my side
1) I set the LTE Signal , Lost all connection
2) I put bearer as LTE , Lost all connection
3) Could be a possibility
Can you kindly forward me or show me the path to where I can change my 900F modem to a more international one , Thanks a bunch !
<3

Something is probably misconfigured or misprovisioned. But regardless, the issue will only be solved by paying attention to details and a process of elimination (of the possible causes).
The most productive single thing that you could do at this point would be to borrow a known working LTE SIM from a neighbour and see if works in your handset. Whatever the result, it would narrow down the possible culprits.
Also, don't assume that the frequencies are correct. Confirm with the carrier that they haven't changed or added new LTE bands.
Make the effort to find out what forums your carriers' customers usually frequent and look at recent posts there for seredipitious insights that you won't find elsewhere.
Don't dismiss the icon idea out of hand. Are your speeds indicative of an LTE connection?
You don't need a more "international" modem. Just a more current 900F one. Or less commonly, an alternate or older modem if your current one has a bug. Do a forum search for threads about changing modems. There are a lot of them. Don't fixate on this - it's one of the least likely possibilities.
Also consider updating to Android 4.4.3 or 4.4.4 which is said to address some connectivity bugs.
