The phone capability will work with any EUROPEAN BASED ROM. Overcome is based on the European version of Gingerbread therefore it will work. Please note most of the Custom ROMS DO NOT come with modems included so you will SEE the phone application, but you will have NO cellular service(calls, mobile data, text etc) until you flash a modem file. The modem files can usually be found in the same thread as the ROM if you look for it.
[Galaxy Tab General] StarLog:
Please look in the devs section, I know they are there.
[Galaxy Tab General] rangercaptain:
The page gives the passwords. Samfirm.com or sonething like that. Its on the download page.
[Galaxy Tab General] VitaZora:
I have a similar problem with my T Mobile Tab. It is unlocked, flashed with Overcome 2.0 RC1 along with the correct modem and although my Tab reads the sim card, i.e. cell number, etc - all I get is a T Mobile web site for the data connection when I open a browser. No phone and no browsing. Wondering what I need to do to fix this.

Thanks.
[Galaxy Tab General] VitaZora:
I am using a prepaid T Mobile data/voice sim bought specifically for my Tab (not borrowed from another phone). But through out my long research today it seems that T Mobile blocks anything other a data sim in the Tab. From what I've gathered, the carrier matches the Tab's IMEI to a data plan only and no other will be accepted - even if it has been rooted, unlocked, or flashed with a non US ROM. I only wish I'd learned this before I bought that pre-paid $50 unlimited sim card . . . . :o

On the other hand, can someone confirm that an unlocked T-Mobile running Overcome 2.0 RC1 will work with AT&T sim card for calls and data?
[Galaxy Tab General] Jyveafk:
hmm, I had it working with other sims. It just took a few reboots/refind the network before it'd settle down on the network. But it did work.
[Galaxy Tab General] rangercaptain:
Just google "T-mobile redirect" and you will find an answer.

What to do ? De compile the Euro Radio.Bin, and Throw in the Band 1700.....Flash it to your device...you are more than good to go.....whoever have the tab that does not have 1700 Standard can always flash their modem.bin to have that Band.

Has anyone done this yet??
[Galaxy Tab General] StarLog:
RangerCaptian he is awaiting your response. lol
[Galaxy Tab General] ua412:
possible to increase sound? Can barely hear while using the phone.

TIA for any responses.
[Galaxy Tab General] rangercaptain:
Click the volume all the way up, then down two clicks. It will be good. This is a known bug in some modem.bin files.
[Galaxy Tab General] rangercaptain:
The modems are binary files so they don't decompile. And the different tab models have different radio frequencies, so you can't just switch to an unsupported frequency.
[Galaxy Tab General] rmsmerd:
Quick question. Im about to buy a tab. When you use the phone option, dose it go through the speaker phone or can u hold the phone to your ear?
[Galaxy Tab General] Jyveafk:
speaker phone alas. never got round to pairing it with a bt headset. but should work fine

[Galaxy Tab General] dliao:
Hum..I don't believe T-Mo's version has that kinda hardware capability. Maybe the ability to choose these various different 3G band is mainly from the European version of the firmware. The hardware may not necessarily supports it.

If Samsung however, actually included some 3G chips that does all the bands, then it would be interesting.
[Galaxy Tab General] mywingtophone:
Sorry but i'm kinda confused does it mean if i hacked my US tmobile streak i won't be able to use the 3G even if i use Tmobile sim card? Anybody enlighten me on this.
[Galaxy Tab General] TX2000:
hack for CDMA?

also if the hack can be do for the cdma network you should also change the esn?.

Because the system will recognize it as a tab and wont enable Voice calls?
[Galaxy Tab General] rotohammer:
I can confirm I have the exact same behavior with my Tab on AT&T. Perhaps is the radio from the Euro firmware? Considering I also lost 3g on T-mobile as well, I would hope its just a crappy radio instead of an intentional crippling by Samsung.
[Galaxy Tab General] x2beach:
If u go into setting Network and put it in GSM Mode only your data will work on ATT in Edge mode..
[Galaxy Tab General] Matt4542:
I know this says T-Mobile, but any way this will work on the VZW Gala Tab? Getting one soon and I want to make phone calls :)
[Galaxy Tab General] calin75:
That's correct. You can make calls but no 3G. So far no fix.
[Galaxy Tab General] rotohammer:
Oh, it works, but the signal level is one bar, and im sitting 6 feet from a cellular repeater :)

Theres definitely an issue with the radio reception on AT&T, as well as the inability to connect to 3G on T-mobile.

It feels as if the radio is detuned, like its trying to pass the wrong set of frequencies through the radio amplifiers ( ie: 850mhz through 900mhz amps) . The reason I think this is for 10 minutes today my Tab displayed an H indicator while on AT&T, but the signal was so low I couldn't transfer any data. I've never seen a spurious H on any of my Euro HTC phones on AT&T, but perhaps Samsung has different frequency selection circuitry.

But, since it should support Edge just fine, and its not, that indicates to me it may be the Euro radio causing the problem, or some other firmware config setting.
[Galaxy Tab General] calin75:
One thing I notice in the bands menu is that you cannot select the 1700 band under CDMA. I know tmobile works with 2100 and 1700 for 3G. Is that the reason why it's only edge when flashing the euro firmware?
[Galaxy Tab General] rotohammer:
I would think so. Hopefully we can get a copy of the US radio or other bits to try soon.

Better yet, the soon to be released AT&T radio.
[Galaxy Tab General] ahbvrh:
Guy,something that might help:

I have tmobile tab unlocked(i got the unlock code from tmobile ,without flashing the euro rom).

I can confirm that I use AT&T sim card and get full reception- EDGE only ,no 3g.

So the fact that you are getting very low signal with AT&T sim indicate it has something to do with the new rom.
[Galaxy Tab General] rotohammer:
Excellent, thanks for that report! Hopefully the difference is in the US modem.bin file.
[Galaxy Tab General] ConceptVBS:
I like where this is going. Awesome job folks. Keep it up! :D

Once again, XDA LEAD THE WAY!!

That should be our slogan! :D:D:D
[Galaxy Tab General] PlankLongBeard:
What about an international tab? Like the Euro one? Can it work with T-Mo's network and use voice? :D
[Galaxy Tab General] ConceptVBS:
I'm sure it can as long as it supports the right radio frequencies.
[Galaxy Tab General] rangercaptain:
You can pair with a blue tooth headset and work that way too.
[Galaxy Tab General] Munk0:
Could I get at at least two of us XDA members to comment on the Samsung Tab as a phone questions I list below? I currently have the Samsung Vibrant but need to hand this down to my wife for a few reasons. I already use my Bluetooth most often and always want for a larger display and even 4.3" isn't enough. So, my questions are:

1) Is it really usable as a phone replacement? This goes into phone reception, clarity, signal strength, etc.

2) Do you have difficulty taking this from location to location much like you would take a cell phone? If you have found a method of transferring this, what is it? Backpack, some kind of hip holster, etc.

3) Is the battery life as a phone comparable to a true cell phone? Even better, compared to the Vibrant which I usually end up with about 10% at the end of each day.

4) Do you have Voice, 2G, 3G still after unlocking it? Seems some people are still saying 2G + Voice. Why is that?

Thanks in advance.
[Galaxy Tab General] mammothman:
Hello,

Ive been looking all over the internet trying to figure out how to get this tablet to work with Mobilicity (Canada). Mobilicity uses AWS frequency just like T-Mobile and Wind (Canada). I first had overcome 2.0.1 custom rom installed. On the xda website they had instructions to load the t-mobile modem with odin which I installed. When ever I try to make a call the phone app tries to dial then says "call ended." The strange thing is that I can receive text messages. Any ideas would be great.
[Galaxy Tab General] Adapt0r:
@Munk0

A1. It works as a phone just fine, perhaps even better because has less size restrictions on antenna. GPS works very well also.

A2. Carrying it is not as easy as Vibrant. It does fit in my jeans back pocket but I can't sit. Using bluetooth headset will eliminate the need to take it answering calls. You can also place/dial calls using voice.

A3. Battery life is way better than on Vibrant.

A4. US wireless carriers treat Galaxy Tab as a broadband devices and ban voice service in original configuration and SIM card. In my experience you can still use it as a phone with prepaid SIM card on Tmobile. It requires also flashing of an appropriate ROM that has voice services and new modem. Unfortunately, modem with voice capability does not provide 3G capability, only EDGE. Another issue is that as soon carrier capture your Tab's IMEI number it will reroute all your web traffic to their web page and ask to pay.

In summary, you will get voice but no web unless you are on WiFi.

In any case wireless customer should pay either for voice SIM card or for Broadband SIM card and services. If you choose broadband you can use Skype as a phone provider.

Hope I've answered your questions :-)

Can somebody please help me regarding this should i have to do some tweaking for this have anyone faced this issue
[Galaxy Tab General] rangercaptain:
Go to the rotohammer modem switcher thread. Everything you need is there
[Galaxy Tab General] kethireddy:
I tried using that but even then i cannot make calls nor receive calls using my AT&T sim, can any suggest me what i have to do
[Galaxy Tab General] GalaxyXero:
I too am using T-mobile tab with an at&t sim and have edge data and sms working fine but no calling...I'm thinking it's the modem bin files I need...(is it sacrilege to work as an at&t authorised rep with a tmo tab lol) Can anybody direct me as to where I can find at&t's appropriate modem.bin? Thank you so much in advance
[Galaxy Tab General] rangercaptain:
For both members:

Go to settings, about, what baseband do you have?

I want to know the last three characters. Example: mine is JK3.
[Galaxy Tab General] kingnarkissos:
Love it!

Thank you so much it works great and was exactly what i was looking for. NOw to get hspa with calling abilities!!!
[Galaxy Tab General] kethireddy:
for mine it says JMA.. how to make it JK3?? I tried the roto's ROMS the v4, v3 ones but they just keep rebooting once i insert the simcard, so i chanegd back to overcome 2.01 which is stable for now but the stuck with the same issue.

Thanks for the help!!
[Galaxy Tab General] GalaxyXero:
My baseband is "i9000ugjk3" now that I just reflashed the correct modem...thank you for the help!

Sent from a Galaxy far, far away
[Galaxy Tab General] kethireddy:
Can you please help me out on this??? on what you did and how did you do that?

update: I got it working i can make calls and receive calls from AT&T sim card, thanks everyone for their valuable inputs it was basically the modem once i changed it to jk3 it worked fine but still when i open the browser for tmobile i am being asked to login to the account i dont know why???
[Galaxy Tab General] kethireddy:
Now that i can successfully make and receive calls from my galaxy tab with both AT&T and as well as Tmobile Sim card, i have only two issues.

1.) when i am trying to access internet using the Tmobile sim i am been redirected to the tmobile site, what is the work around for this? is there is any?

2.) I am trying to use the modem switcher using the AT&T Sim card but i am not getting any 3g for the AT&T it is still on edge and also i cannot make any calls when i change it to the 3g modem? does anyone have this issue? any suggestions please..

Thanks for all the inputs
[Galaxy Tab General] cd-rw03:
I just bought a T-Mobile version. Would you like to share what exactly you did to get phone function? Thanks!
[Galaxy Tab General] kethireddy:
Firstly i downloaded the JK3 modem from this post

http://xdaforums.com/showthread.php?t=1069727

now i hope you know how to use odin3 v1.7.

i used P1_add_hidden.pit file for the pit in the odin and Roto_JMI_fullV2 for the PDA and the JK3 modem ( you will find the modem in the updates folder of the file you will downloaded from the link provided) for the phone and click start and once everything is done.

I checked the APN settings and selected GSM only option in the wireless section and it is working like a charm apart from the minor issues....But it is awesome...do let me know if you have any issues.

P.S.: mine is the unlocked and rooted version of T-mobile Tab i hope yours is the same!!!1
[Galaxy Tab General] rangercaptain:
2-- google t-mobile redirect for that solution

3--you wont get 3g using an at&t - t-mobile combination. The hardware isnt compatable for the 3g network. So voice and EDGE data is the best you can expect.
[Galaxy Tab General] kethireddy:
Thank you!!! I sent PM regarding the same issue please ignore it..
[Galaxy Tab General] rangercaptain:
Oops, I replied to the redirect issue by pm because xda doesn't want us to discuss it in their forum.

Voice+3G in Germany

I've been reading through this thread and still need clarification:

I bought a t-mobile Tab here in the US yesterday and my brother will send it to me to Germany (I'm studying abroad)

Since I'll be in a German network then I should be able to have voice+3G w/o problems, right?

Any advice on which ROM/Modem to use to accomplish this?
[Galaxy Tab General] rangercaptain:
No, two modems needed.
[Galaxy Tab General] williamhung:
Thanks RangeCaptain for your quick answer...

One more question (confirmation), I kept on reading and got a bit confused...So will 3G work on a UMTS european network? I actually only need 3G, while voice was just would be a nice addition. If the 3G doesn't work then I'll let my brother keep the tablet since the shipping would be kida expensive.
[Galaxy Tab General] williamhung:
It seems like 3G+Voice actually works abroad, found the answer here:

[Galaxy Tab General] rangercaptain:
That member was telling many lies! He was the only person who claimed 3g and voice on a US t-mobile tab on international networks. Not one other person has confirmed that for any other country. Sorry, friend, it just doesn't work.

There is a $1,000 bounty for anyone who can make this work, and it is still unclaimed.
[Galaxy Tab General] lamiguete:
I can confirm US T-Mobile GT-P1000 carrier unlocked working on Gingerbread XXJ1 with CF-Root kernel is working on HSDPA+voice calls with baseband T959UVJK2 after activating "Select GSM & WCDMA All Bands" on automatic for Spanish carrier in Spain enabling data while roaming (the tab thinks it is roaming) it gives some odd reads on signal, both cell and wifi but both are working fine
[Galaxy Tab General] rangercaptain:
I heard from a few friends for Isreal and Eastern China. So which carrier in Spain do you have please?

And the current question is regarding Germany. Any info anyone has, please?
[Galaxy Tab General] lamiguete:
I've tested Simyo (spanish KPN carrier) I can test Vodafone if you want to know if it makes any difference

[Galaxy Tab General] hexxamillion:
I have a CarPC worklog in the MP3Car.com forums where I have mounted my tablet as a replacement to my car radio..no need for it.

[Galaxy Tab General] topflight05:
Did you figure out the Tmobile sim issue? I am able to get data if I delete my entire EFS folder, but I think that's wrong. If you figured this out, would appreciate some help. Thanks in advance.
[Galaxy Tab General] topflight05:
for fixing the tmobile redirect - is this the empty "EFS" folder trick? this worked for me but I was thinking someone else found a better solution?
[Galaxy Tab General] rangercaptain:
It's the back everything up two times, then empty the folder method. Is that what you are referring to? At this time its all we have.
[Galaxy Tab General] williamhung:
That sounds great. Actually I'm living in Spain right now and also have Simyo.ES and was planning on getting Simyo.DE once I get to Germany as well.

Can you please link me to the ROM/Modem combo you're currently using?

-a little off topic but- The "roaming data trick" also works for the Moto Cliq BTW
[Galaxy Tab General] lamiguete:
It's stock GB rom P1000XXJQ1 with cf-root jq1-3.3 kernel modem is T959UVJK2(radio vibrant jk2)

U need to enter service menu to enable all bands in order to get both HSDPA and voice.

Hope it helps
[Galaxy Tab General] pharoadon:
Where is the service menu and how do I do this? This may be why I can't make or receive calls. Thanks!

Edit: Nevermind, I just flashed JL5 and now everything works...3g + H + voice calling + sms...everything!..on an unlocked tmo tab using a southbank sim!
[Galaxy Tab General] rangercaptain:
In what country are you? I don't know "southbank". Thanks.
[Galaxy Tab General] pharoadon:
Japan...sorry for not stating that in my earlier post.
[Galaxy Tab General] rangercaptain:
So please be clear, many peopke ask about this.

You are using a US t-mobile tab in Japan, with a "soutbank" sim card, and you have voice, sms, mms, and 3g data without the modem switch?

What modem works for this? Settings, about, baseband?

Thank you for being clear.
[Galaxy Tab General] pharoadon:
Yes that is correct...US T-Mobile Tab...Southbank SIM...voice, sms, mms, and 3g data without the modem switch!!!

First thing I did was flash Overcome 3.0 by following the instructions on their thread word for word. The instructions stated which modem to choose if i'm using a US T-mobile Tab...but that modem must be for people with T-Mobile as a carrier because I could not make or receive calls with it here in Japan...though everything else worked fine...before ever attempting any of this I read and read for 2 weeks on XDA while waiting for my Father's Day gift (Tab) to arrive...so being a tiny bit "knowledgeable" I assumed the modem was the culprit...I found the thread where irkkso recommended the JL5 modem...took a blind scary leap of faith and flashed it without being sure if I was doing it correctly using Odin...after receiving the good to go green success message from Odin...placed a call...heard a ring and jumped for joy...checked to see that everything else still worked and it did...the Overcome Rom even provided all of Southbank's APN info...so Rom + JL5 = success for me in Japan...I know there have been issues getting this to work with TMO in the US...hopefully someone figures it out before I get home next year because this is awesome!!!

Edit: There is one problem though...as triplex76 pointed out in that other thread...the volume for the JL5 modem dialer has 7 steps though only 5 steps are supported..so the last 2 steps actually decrease the volume instead of increasing it...that's the only problem I've found so far...if there is another modem that would remedy this...please let me know and I'll test it out...Thanks
[Galaxy Tab General] rangercaptain:
This confirms what I thought - US t-mobile network is disabling the tab. It's not something on our tab, but something t-mobile does to our tabs.

As you found out, you can flash any modem, so go to the modem stickie on the development thread and try any you like.

Could you do me a favor? Dial *#2263# and let me know what bands are selected? Or take screenshot of each of the 4 screens? Thanks for the good reoprt and your help.
[Galaxy Tab General] pharoadon:
Oh...Thanks for showing me how to access that...on the BAND SELECTION screen AUTOMATIC is selected...on the WCDMA BAND screen the selected options are 2100, 1900 and 1700...850 is not selected...on the GSM BAND screen the selected options are 850, 900, 1800 and 1900...GSM ALL is unselected...on the COMBINATION BANDS screen the same previously mentioned 7 bands are selected...WCDMA 850 is unselected...hope that helps

You can flash JPE modem, put in the correct apn settings, put it in gsm only mode, and you will have voice+EDGE.
[Galaxy Tab General] huiman1:
finally got it to work after "redeleting..." thanks

fyi, i used a the same t-mobile sim card on an unlocked international tablet (p1000) and i was also only able to get voice+2g or 3g without voice. however, i didn't need to delete or modify ANYTHING. i didn't even need to change APN. i literally just took my at&t sim out, changed the modem.bin, and put the t-mobile sim in. everyone probably knew this already though.

Well, not everybody.
