I am currently using rotohammer's JMA 2G modem for my phone calls, but it is causing a lot of no service sign compared to the original T-mobile modem...
What is your T-mobile modem? Does it cause any problem with weak signal?

I actually didn't notice at first(since 3g is patchy where I live) but since switching to the overcome rom my tab will connect to 3g but as soon as data transferring begins/resumes it will switch back to "H" which is thier high speed "Edge" network.
Baseband version: I9000UGJK3
Could this be the at&t modem that overcome provides?
Are there any other modems I could test out that might be better?
Thanks for your help.
found what i was looking for here
My toolbar still shows "H" during data transfers ("3G" otherwise) but the speeds seem fine, so I'm not sure what the issue is with that.
H is HSDPA which is faster 3G. http://en.wikipedia.org/wiki/HSDPA
Ok that makes more sense, thanks.
Speeds seem to be the same with the jm2 modem, anybody else done testing on the rogers network?
I live in NZ and use my captivate on the telecom xt network (3g 850/2100) so there is no problem with the frequencies, except since i upgraded to a GB rom my phone has not been picking up the network and is instead trying to connect to another network (vodafone) gsm 900mhz band.
I tried reflashing to stock 2.1 rom but my phone still didn't connect, tried a bunch of different modems with no luck. I'm on cm7 atm.... which doesn't allow typing codes in the dialer to check which frequency the phone is connected to and all that.
Anyone know what could be wrong? Its not a reception problem, i have another phone i tried my sim in and get almost full signal. Its a problem since flashing to dlev 4.2, after being on serendipity 3.5 without fault since last year.
also: telecom has no gsm frequencies on the xt network, vodafone still has gsm... so i'm thinking it could be that my phone is just not connecting to wcdma for whatever reason.
Try new modem?

^ i've tried like ten modems including those most recommended.
btw my phone got reception today at uni, how in cm7 do i check what frequency my phone is connected to? i think 850mhz 3g isn't working... even with 850mhz modems...
Have you tried the modem dance?

Hello,
I have a galaxy tab non branded with overcome installed.. I`m trying to get Tmobile 3g on the tab but no matter what modem i installed i`m always getting edge.. I tried with roto modem switch.. but still no 3g.. Tried to flash with tmobile stock modem but no 3g..
Model number GT-p1000M (SGHI987)
Firmware 2.3.6
Baseband T849UVjjB_ROTO-3G (after useing roto modem switcher)
Kernerll 2.6.35.7
Overcome-v4
I have tried the froyo, gingerbread now trying it to get 3g on overcome..
Please suggest me if i have to make any other changes to get 3g on tmobile network..
Thanks
bell mobility tab no 3g on tmobile
No one is having this issue ?
No 3g, just Edge signal
I too have a similar problem with no 3g signal. I'm in Bolivia and I have 3g coverage with my provider. I had upgraded to Gingerbread in hopes this would solve the problem. No 3g. I then installed the different modems and I still had the same (no 3g) problem. After this didn't work I went back to Froyo as a last ditch attempt since I had rooted Froyo in the beginning and thought maybe something got messed up. I've never seen a 3g signal here and don't know about the U.S since I've only use it here. Is it possible that the Galaxy Tab 7 3g just does not work in Bolivia? By the way, I've checked all settings and done everything to make sure things are correct. Any ideas? Thanks.
for @polapine, this is answered in another thread.
Basically the conclusion is that T-mobile uses different frequency for 3G/HSDPA, that a normal unbranded tab modem hardware is simply incapable of using. (1700 Mhz)
On the other hand, a T-Mobile branded tab can also operate at the "usual" 3G band in other networks in Europe/Asia/Australia (2100 MHz)
I have a galaxy tab 7 from T-mobile. I have updated my firmware to newest overcome rom but I don't know what modem I should use for it. I live here in the Philippines which is part of Asia. I want to use a modem with call and 3g function. Additionally, when changing modem, will it wipe out my system? Thanks in advance.
I have the T-Mobile SGH-T849 too.
Use JPZ modem in Asia/Australia/Europe should be fine.
No, flashing modem will not wipe your system.
After flashing go to setting About Phone and check your baseband
it should have changed to something-something-JPZ
yup, I'm using JPZ on my tab, but I don't have 3g.. i only have edge.. can I still revert back to having 3g instead of call?
which network in the Philippines? maybe we can find out what frequency your network use.
It is weird. I thought asia uses GSM 900/1800MHz and HSPA at 2100MHz, which is what the JPZ does.
The original modem (JJB) can be found here.
http://devphone.org/files/gtab7/modems/
But T-Mobile modem is meant for T-Mobile user to have 3G, even them won't get voice call with it.
Are you sure your area has good 3G reception?
I'm not familiar with frequencies and such, but i'm using Smart here in the Philippines. Can you help me determine what network I should use?
http://obsessivecoder.com/2010/09/19/philippines-gsm-frequency-band/
Smart Communications 900 MHz/1800 MHz W-CDMA (UMTS) 2100 MHz
Exactly the same as other GSM I know in Singapore/Indonesia/Australia
Can you check your setting just to make sure you are not restricting your wireless to 2G only?
EDIT: I am not sure if you edited your post. But I thought I read you get E only.
Now I can't see any of that in your post.
Do you get mobile network working at all?
If not, then the issue is with your APN.
You need the right APN for Smart
i've set it on wcdma but it does not pickup any signal. i still only have edge.
Menu -> Settings -> Wireless controls -> Mobile networks -> Uncheck .. only 2G
I got more info on APN:
APN Settings for Smart Bro
Postpaid APN: smartbro
Prepaid APN: smartbro
APN Settings for Smart Buddy, Smart Gold
APN: internet
i'm still on EDGE.

forget about the references to 850MHz,
access the menu and make sure you have stuff selected for 900MHz 1800MHz and 2100MHz
normally we have 3G on 900 and 1800, and 3.5G on 2100MHz
still not working
you can confirm that the same SIM card in other phone, at your present location, gets 3G?
yup, on my galaxy y, 3g is ok
and APN in that phone is the same?
EDIT: try other modems. KM2 for example
went back to t-mobile modem for the mean time. will try out km2 later. from the modem list, most of them are for gingerbread 2.3.3, but mine is 2.3.6. will there be any conflict with that?
nope.
even froyo modem works.
we use JPZ through to ICS as well.
Does T-mobile modem gives you 3G?
yup, it gives me full hsdpa connection speed.
hi mahan21,
Not sure if you are still looking for the modem.
try T959UVJL5 modem from the Galaxy S T-mobile.
I was baffled because I am really sure I get 3G/H on JPZ but I check again I can't.
I even restock to GB stock safe, no luck.
So after searching, I found the JL5 modem
and it works!
3G/H and voice call on T-mobile tab in Asia (Well, Optus Australia but it is the same GSM/UMTS combination)
Get the modem here:

(the one the OP attached, not the multiupload which is dead)
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...)
