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.

I need help with a Galaxy Tab that a friend of mine has.
She has purchased a Galaxy Tab from Telstra and it is Next-G capable. However she wants to be able to use her Optus SIM card (she does not like Telstra). She got the unlocking code but something went wrong and now the Galaxy Tab isn't registering any SIM card.
I was wondering if someone could kindly point me in the right direction in perhaps rooting the phone and installing a custom firmware (or perhaps a firmware which pre-unlocks the phone to use any SIM card).
I am fairly familiar with flashing as I've done it a lot on my Galaxy S, however I'm finding it difficult to find the right steps on how to do it with the Galaxy Tab.
So, could someone please provide a helpful link? or point me in the right direction, would be a great help as I should be able to do the rest myself.
EDIT: Perhaps the information below may be helpful
Model Number: GT-P1000T
Firmware version: 2.2
Baseband Version: P1000TDVJJ3
Kernal Version: 2.6.32.9 - [email protected] #1
Build Number: FROYO.DVJJ3
have a look here regarding the "debranding" of your device ! http://forum.xda-developers.com/showthread.php?t=1000132 . i hope it help !
Thank you very much, will have a read as soon as I get back from a 12 hour shift
Two things....
1/- What 'went wrong' exactly? Can you provide a little more info? Also, curious as to what code you used to unlock and where you got it from? Reason I ask is there isnt much that can go wrong really. It either works, or it doesn't. It's possible the wrong bands are selected if no sim is registering. What band is the asterisk next to when you dial *#2263# ? Just set it to 'Automatic' if it's set to anything else.
2/- I'm not 100% sure, but I think the modem on the Telstra tab may be different. Yes, both Optus and Telstra are 3G GSM, but Telstra use the 850Mhz band for 3G. Optus/Vodafone use 900Mhz. Once unlocked, the Optus sim should register, and you'll get data from GSM, just won't get 3G out of it.
Can someone else that knows tell whether a 850Mhz 3G modem can be flashed to support 900Mhz, or is it built into the hardware?

I have been trying to do the reverse using non telstra GT-P1000 on 850mHz (nextG) an have come to the conclusion it wont work
Trying to go the way you are would just I thought require a modem flash maybe? and changing the settings to automatic as stated already
That said can anyone confirm GT-P1000T is the only model capable of umts 850mHz (ie. next G)
Basicly the tabs are at&t compatible or t-mobile compatible. There are a few odd network carriers out there that don't quite work on either st of frequencies.
Just set the wireless settings to automatic, check for correct apn values, and reboot and wait a few minutes. The tab is slow at connecting if you have a lot on your sd cards.
You can flash modems easily and find what works best.
Hi everyone,
I bought a Samsung Galaxy S GT-I9000 (16gb) in Singapore and was using it fine on Singtel's network (signed a contract with them). Now I have moved back to Canada and brought my phone with me assuming that all would be ok to use it with the network here. However I'm having big problems with this one network I just signed up with (Virgin Mobile).
85% of the time I cannot connect to it: voice calls and SMSing won't work nor will the data work on it, the only thing it says is "Emergency calls only". Then at other times everything will seem to connect and work fine - I can make calls and use data.
Virgin Mobile will not support me much because they're thinking it's the phone's problem, if I use the phone they gave me (a lower-end model) it works fine.
Here are some details of my phone:
Firmware version
2 2
Baseband version
I9000DXJPA
Kernel version
2 6 32 9
root (at) SE-S604 #1
Build number
FROYO DXJPA
If I check out the status, it usually says this:
Network
Unknown (switches to VIRGIN when it does work)
Mobile network type
UMTS (switches between that and HSDPA and GPRS)
Service state
Out of service
Mobile network state
Disconnected (switches to connected when working, and even when it's not working sometimes)
I have Network mode set to auto mode (GSM/WCDMA). I've tried to switch it to GSM only but that didn't seem to change anything.
I'm wondering if there's some kind of configuration settings I still need to do with the phone? I'm also wondering if it is the network I'm with right now? Virgin Mobile isn't one of the bigger telcom companies here and I'm thinking that if I switch to one of the bigger telcoms, will it work better?
Something else to add - before I signed up with Virgin I was using my phone with a pre-paid service (called Chatr) for voice only and it was working fine.
I'm sure this phone can support the GSM frequencies here.. can't it?
I also still have the Singtel customizations on the phone. Will it help if I remove it?
Any help would be greatly appreciated!
Thanks a lot!

You can always try flashing a different MODEM (Radio) .. And you might as well upgrade to a 2.2.1 firmware, if not GB.
hmm.. do you know where I can learn how to flash my phone to a different (and more appropriate!) modem? also where to find an update to the firmware?

Just search in these forums. It's all there. You can easily flash a new radio package using ODIN. Better yet, try one of the custom ROMs from the I9000 Android Development section.
Hi all...
first off.. .the search is not working on the site so I was unable to search for this information.
I have a froyo galaxy tab with all the phone features enabled (edge data only though). I am in the U.S. and using a t-mobile tab on the Atnt network. All this works GREAT currently (though would love to have 3g and phone at the same time).
My question is can I upgrade to gingerbread or honeycomb (when it is released and no longer alpha) or will doing so remove my phone features?
Is there a modem firmware that allows 3g and phone at the same time yet?
no...not for Tmo tab on ATT especially....even Tmo tab on Tmo network you can't get voice and 3G at same time...only voice+2g or 3g only with modem switcher...we att tabs can get 3g and voice simultaneously tho...please search galaxy tab development section under Modems please
thanks DPAIK
I have modem switcher, but don't use it too much I just leave it on 2g+phone which works reliably... which is most important.
Anyone have an answer about potentially upgrading to gingerbread or Honeycomb with a tab that is in the U.S. and has the phone enabled?

I have an ATT tab on gingerbread and can confirm that voice and data work fine on the overcome ROM. It should be the same for the T-Mobile tab since they are both GSM based, however you still won't be able to get 3G service.

When you upgrade to gb the modem switcher will still work.
been on Overcome since the beginning...and it rocks...follow instructions on their thread to get it up and running...you need to flash the Stock European Gingerbread ROM first put you can download everything you need on the Overcome site...good luck
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)
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...)
