so after 6+ hours of searching for an answer i'm giving up and asking. i've found many tutorials and guides on how to use a t-mobile tab with voice calls and edge data but not 3g. now i dont know if im crazy or just not understanding this right but baseband determines if it will allow the phone to pick up certain signals including phone calls and data such as edge or 3g. therefore by upgrading the baseband on my tab i should be able to use these services, together or however I choose, depending on if the modem.bin i flashed works in my area. please someone tell me if i'm wrong, because i'm not 100% sure on all of this.
anyways, I have 2 galaxy tabs. 1 purchased in Hong Kong and the other purchased in mainland China (but this is a branded t-mobile tab in black). The info is as follows for firmware:
HK Tab: PDA: P1000XWJMK | PHONE: P1000ZTJK1 | CSC: P1000OXAJME
T-Mob: PDA: P1000XWJMK | PHONE: I9000UGJK3 | CSC: P10000XAJME
Both ROMS on latest Overcome firmware/kernel, rooted, and all 4 settings in lock status(*#7465625#) are set to OFF.
SO onto the issue... I'm using China Unicom (CHN-CUGSM) for the Hong Kong Tab with working HSDPA and voice calls in mainland China. When I insert this SIM card into the T-Mobile tab all get is EDGE/Voice calling. Now. from my understanding, all I need is the Asian/HK modem.bin(P1000ZTJK1) flashed onto the T-Mobile tab and it should work on the China Unicom network, because again from what I understand it is the carriers in the states that are blocking the use of 3g with voice calling. I could totally be wrong here and please correct me if I am wrong. Lol for all I know it could be as simple as differences in hardware.
Another question that I have is: I have a US AT&T 3g sim in a blackberry. It currently receives 3g data/voice calling on roaming. If I wanted to use this same service with the T-Mobile tab is it possible with a new modem such as the one I have on the Hong Kong tab? Also, if I decide to take this T-Mobile tab with the AT&T sim in it to the states do I have to switch modems?
Sorry for the ridiculously long post. I just havent found anything for a person hoping to use a T-Mobile tab in China regularly that is in plain English. Found many Chinese sites, but they use different terms for flashing and what not (ie they call it "brushing" i think).
(SQEAL)
SUMMARY of QUESTIONS for EASE of ACCESS, Lol
1) Will flashing a Hong Kong baseband(P1000ZTJK1/ZHJK1) to a T-Mobile tab allow access to 3g/voice service in Mainland China on China Unicom?
2) Will an AT&T 3g sim on Roaming (with 3g/voice currently working on a BB in roam) work in the T-Mobile tab IF said tab had the HK baseband? (With current baseband doesn't do HSDPA or 3G.) and again, on China Unicom...
3) Will using this T-Mobile tab in the states with the AT&T sim in it work in terms of voice/data (if so, what kind? EDGE only?)
4) Will I have to switch modem.bin when visiting the USA if using the AT&T sim in the T-Mobile tab?
So i managed to get everything working and just in case anybody is wondering here are the answers that I've found.
1) Will flashing a Hong Kong baseband(P1000ZTJK1/ZHJK1) to a T-Mobile tab allow access to 3g/voice service in Mainland China on China Unicom?
A) no. At least in my case. I got it so that both my hk tab and t mob tab were on the same firmware, baaeband, kernel, etc. And while my hk tab was 3g and voice call capable the t mob tab was only getting edge and voice.
2) Will an AT&T 3g sim on Roaming (with 3g/voice currently working on a BB in roam) work in the T-Mobile tab IF said tab had the HK baseband? (With current baseband doesn't do HSDPA or 3G.) and again, on China Unicom...
A) nope. Im guessing by this point the modem is only half the problem? Found a tutorial titled "Getting 3g and voice on a Tmobile Tab[Updated Nov 22,2010]" on xda and after following this guide the Tmobile tab is fully functional on China unicom with hsdpa and voice calling.
Sorry don't know answers for last 2 questions but Im guessing i will have to flash a new modem if tryin to use in the usa.

Hi, I ordered a GT i9000 model from Europe (italy maybe) and live in Canada. To date, I have never seen it go on 3g (assuming a little 3g icon shows up when that happens) or seen an option to go 3g. I'm on Rogers with just standard voice plan so I was wondering if it was the plan or the phone?
Sorry if it's a stupid question. I'm new to this.
OK, so long story short. I have a client who bought 4 tabs. 2 UK GT-P1000 and 2 US ATT. He was told by another service provider that the GT-P1000's would not work in the states, so he bought 2 ATT Tabs. He lives in states part time and in Argentina the rest of the time. So he wanted me to make the ATT tabs have the phone (which he had seen on the UK GT-p1000) functionality, which I did using rotohammer's original method with Odin. I flashed the Russian and then Euro versions and then added the bell Modem. My client only had an ATT sim card with data only, so he dumped his tab contract (and paid the fees) and picked up a cheap blackberry with phone and data plan. We used this sim in the tab and he was very happy here in the states. He has now returned to Argentina and is not able to use the tab using the ATT Sim card. Can anybody point me in the right direction. Is the bell modem the wrong one? Is there a certain provider that he would be better using? Any help appreciated.
Can he use a Movistar sim? They are throughout South America. They are the same as at&t, so the bell modem would be a good bet.
That was my recomendation to his IT guy in Argentina yesterday. Anybody else know any more info. I was actually thinking the movistar tab was way cooler than the ATT with it's sat tv capability.
I agree. Movistar is good down there and you can add credits easily. That tab is very expensive!

So I'm writing a tutorial using RotoHammers Thread on unlocking
LINKhttp://forum.xda-developers.com/showthread.php?t=843323 - How to carrier/SIM unlock the Galaxy Tab
I am having him install titanium, astro and a custom gcript.apk that will allow the tech to install the custom apk using titanium and then have him back up the tab completely using clockworkmod (rotos custom, pre installe here in states) then some scripts in gscript that will run the /efs backup and the another to run rotohammers adb commands from that thread. (I hope that this all works)
The I have to have him pull the APN settings ( anybody know where these are so I can write a script of adb commands to back them up) and have him test the tab and correct the apn settings if they are wrong. Still have to find the Movistar APN settings for Argentina as well.
Thanks.
You are exactly right. In wireless settings make sure roaming is off or you will burn through your credits.
Here is your apn:

dude, you should get that tab unlocked and use an Argentinian SIM when he's there and then when he comes back to the states he can plug in the ATT SIM, problem solved.
Check the date - your advise is 3 months too late! Thanks anyway.
Hi all,
I'm thinking about getting a T-mobile galaxy tab to use it oversea - Singapore to be exact (M1, with the same band with T-mobile). I've read that you can unlock the Tab, but cannot have 3G and phone functionality through T-mobile (they blocked it).
My question is, if I reflash it with Asian or European ROM, will I be able to use it as a normal Tab originated from here (with 3G + phone)?
I've read around but could not find the specific answer to my question (as most answers are focused on US soil).
Thanks!
help please?
The data voice block is for US only, and some countries you get all the functions. Isreal and China, for example, get 3g and voice.
I bought a unlocked Samsung Galaxy tab t-mobile version running overcome kratos,
it has the call icon but when you try to make a call, the call cancels out. the 3g data works great just no call function I think I need to add a modem but not sure which one & how. I was looking at the Galaxy Tab modem list forum
would a T mobile Stock Modem work for me or something else
(the guy I bought it off said the phone works but its clearly not set up fully yet)
model: p1000
Firmware 2.3.3
base: t849uvjjb
Kernel version 2.6.35.7 overcome v3.3.1 #101
Using overcome v 3.1.0-kratos
Canada Wind-mobile (same as tmobile 3g 1700/2100 ban but they have no EDGE 3g only)
any help would greatly be appreciated thanks in advance
I also have a SGT7 on Wind. I have done some reading and the problem is that the TMobile radio does not support both 3G Data and voice as the Tmobile tab was not designed to act as a phone. People have flashed a different modem (euro or asian I believe) but you will loose 3G (Wind Home) and will be constantly roaming on Wind Away (incurring charges). I have also read that people have had limited sucess flashing a Galaxy Vibrant modem (I believe they use the same modem hardware) but there are so many different users on various networks that finding someone who got this to work on an AWS network is a difficult task.
I was considering giving this a try myself but havent taken the plunge yet. I was also on the Kratos 4.0 rom but found that my Tab was restarting itself when playing any graphics intensive game. I have switched to the Russian stock rom and have found that the Tab is quick and gets solid battery life.
By the way, I activated my tab on the Super Smart $29 plan and have been having great sucess with this combo.
Hope this helps.
Thanks phone swapper I was starting to thinks no one cares about the newbies here
I was thinking of using a modem switcher but that still would not solve the 3g calling looks like we may have to use a mobile voip to get by til the code is cracked, if I find something I will let you know.
Hi everyone, noob here so dun wanna start a new thread with my question since it is related to this matter and I was wondering if anyone can help me because I really can't figure it out anymore.
I have an International GT-i9000 purchased with Hong Kong and system specs I have running are
Gingerbread.ZSJW4 (recently flashed the official ROM from Hong Kong cuz I am anal and want to keep the same languages)
Kernal: 2.6.35.7-I9000ZSJW4-CL1147074
[email protected] #2
Bandbase version: i9000ugkg3
And I use AT&T in New York (I know, worse plan to use in dead zone capital of the US)
I had flashed the ugkg3 modem on it because the JW1 modem that was with the official ROM wasn't working out for me and I had heard this modem was the best for my area. Before it would either not pick up a signal when coming up from underground or the signal just go dead, which did not happen when my phone was on Froyo (on Froyo I did not have 850mhz enabled and it worked alright outside and sometimes in the house)
At first, the KG3 modem worked wonderfully, I was able to receive data in my house and was on 3 bars (compared to none to one before). However, I now notice that while I do have full bars, I cannot receive or send messages or phone calls (even though my brother's Note is able to do all that and it was next to my phone).
I also happens when I am outside as well.
The other day I was standing in front of the AT&T store near where I am and I still don't pick up a signal.
Or it would lose the signal and never pick it up again.
Unless if I really can't use 850mhz on my phone, which does not make sense because AT&T uses 850mhz.
I am real hesistant to try another modem, and I cannot figure out if it is a hardware issue or network issue, or is it just the wrong modem?
Can someone please share any insight?

my other question is, phone is not ICS, and I found the nexus S one...will it still work?
and can I just extract out modem.bin and flash via ODIN ?(somehow my phone won't do CMW recovery...)
