[Q] tmobile and unlocked Samsung Tablet

I apologize because I think I may have posted my questionin the wrong place two days ago. I'll see if I can delete it. I hope a few people here can answer me.
My question is that I already have a voice data account with tmobile and SIM card for that account in my Galaxy S Vibrant. Can I remove the SIM from the vibrant and place it in this particular International unlocked P1000 Galaxy TAB to use this P1000 as phone and data just by moving the SIM card? Or do I have to still notify tmobile that I am moving the SIM to this unlocked P10000 device? And will all features of this international version then work....the phone and 3G data with my SIM from the working Vibrant? If I can just move the SIM card is there anything else that I have to know or have to do?

All US carriers consider Samsung Galaxy Tab as a mobile broadband data device and make difficult to walk around this decision.
Since you are going to get a Tab not from T-mobile, it will not have your IMEI number recorded and might treat your Tab as a phone allowing for both voice and data. The issue might be only that you will not get 3G for data because software and hardware do not support unique 1700/2100 AWS frequency bands utilized by T-mobile in the US.

Do you have the phone dialer icon? If not you will need to flash a rom so you have a dial pad.

Thank you both for some answers.
The reason I was looking at this imported version was because I read that this Samsung tab already allowed telephone and since I already had a working 3G and telephone SIM from tmobile I thought this was the way to go. I really wanted this Samsung Tab to do telephone so that was the real reason even looking at this particular item.
No I have not ordered this yet. I wanted to ask the questions BEFORE I paid the money to find out that it will not work in my situation?
So what I am reading from both of you is
1. I probably will not get 3G, and
2. I would need a dialer Icon from somewhere.
Not getting 3G is a "do not purchase this" issue then for me.
Any ideas on the Samsung Tab then? I do NOT mind signing it up with tmobile, I just also wanted it to do bluetooth phone, 3G and then only need to carry this one device.
You guys are great
Thank You

The T-mobile tab can be unlocked. After it is unlocked you can flash it with a European rom and Roto's modem swithcher. You can then run 3G on any carriers sim card and switch to 2g (edge) and phone with T-Mobile using Roto's modem switcher.

WoW. Thanks for that info.
Wonder if you do all this and will hear incoming calls if you are in 3G mode. (i guess this is what the Roto's switcher does, it places it in 2G or 3G). Then if you could/would hear it ring while in 3G, for an incoming call you would then have to switch to the 3G mode with this Roto switcher? Trying to get the call before voice mail kicks in? (what is it, an icon for an on-off type thing of its installed software).
Has anyone actually done any of this?

Yes its been done by many Tab owners. Search the galaxy tab developers section for how to flash roms, modems and kernals. You'll find a treasure trove of information on how to improve the Galaxy tab. The Developers here at XDA are an incredible group of people and most are willing to share their development findings with other Tab owners.
Good Luck.

Do I understand you correctly saying that T-mobile Tab after flashing can get 3G and voice phone on any carrier Sim?
This would be my "dream". So far I can only get either voice with phone Sim or 3G data without phone capability. BTW, the latter requires Sim with paid data service separate from smartphone. Roto's swither is just a utility flashing either phone modem or 3G data modem.
Would you mind to give more details supporting your post.
P.S. European Tabs have phone voice capability and a dialer out of box. Not extra flashing is needed.

Voice + EDGE data OR OR OR 3g data/ no voice NOT NOT NOT both!!

You cannot get 3G data and voice at the same time on the Galaxy Tab. With the modem switcher you can switch between 3G data only and 2G (edge) data and voice.
Until the development community can come up with a method to run 3G data and voice at the same time (if possible) the modem switcher is the best answer to the problem.
Also the the T-Mobile Tab can be unlocked so that any GSM carrier's sim card can be used. This allows you use the sim cards from Simplemobile or any other GSM carrier and not be locked into a T-Mobile sim card.

Anyone live here in MD and want to make some money setting me up doing this thread hack/install for me?

I am a T-Mobile customer and here is set up on my T-Mobile tab:
1.Tab running Roto's JME v4 (European firmware that will allow voice+edge)
2. Roto's Modem Switcher (switch between 3G only or Voice+Edge)
3. My old Vibrant SIM card (Voice+Data)
4. Broke IMEI so i could use my Vibrant SIM to go online and stop getting re-directed to t-mobile site.
So basically i use my tab as a phone now but only getting voice+edge, if i want faster speeds i switch over to 3G using the Modem Switcher. The only way you can get both voice+3g is if you unlock the tab and use AT&T sim, if you want to use T-Mobile sim that option is not available unless a modem comes out that allows both voice+3g.
Hope this helps in making your decision.

Hello and thanks very much,
Seems that you are a match to my scenario. Are you happy with everything the way it works now (voice/2Gdata).
Do you have Caller ID working in any setting/switch?
And to make sure I understand this part. If I am in 3G mode I will NOT ever know of an incoming call by any pop up or beep or anything? The only way to know if some one even tried to call is to go to voice mail from 2G/voice being switched? (se, I am not a voice mail user. i have my Vibrant tmobile voice mail turned off at tmobile.)
So what i read at the top of this thread about having to unlock it is not the case for me?
Do I have to remove anything or add anything else?
Having to do anything at all other than these 4 things you listed for me is not needed?
That's very interesting. How do you "break" IMEI?
And these installs that you did list, is this the exact order to do these things?
And what about the thing where someone said I need a phone icon?
How do you switch to phone mode and dial?
BTW how is it as a phone with Bluetooth device? How is the volume (at both ends). Can you hear okay?
And I think one last question. If you happen to be in a wifi spot and using the tab in wifi mode, does the phone work at all?

No true. If you flash the at&t tab with Roto firmware, and install the bell modem, you can have 3g and voice with an at&t sim card, but again, at&t tab only does this.

Dear noreturn
If you so eager to get it and need help send me PM. I am almost your neighbor.
I would not recommend you breaking (meaning erasing file containing) Imei.
You have two other options
- get At&T tab, unlock it use on Tmobile with Vibrant sim. You will get voice and Edge which is very usable around dc-md-va. 3g will be only on att.
- get European Tab that is unlocked and use it on same way as #1 but no extra firmware flashing is needed.
Unlocking of either Att or Tmobile Tab is easy the same is true about flashing. however it takes more time.
Caller id works as on any phone.

Yes I really do want to get this samsung with voice.
So are you saying get this version of the Samsung tab and use my tmobile vibrant SIM?
Then install that modem switcher thing is all? And I guess I read about a dialer icon or something?

European Tab has everything for voice and Edge but Tmobile tab just cheaper.
Dialer comes installed with European, on Tmobile it appears after flashing.
Hope you understand your options. Modem switcher helps only if you have paid data service or erased your Imei. The last case is legally questionable thats why I would not advise it.

True. I should have clarified my response in that I was referring to the T-Mobile version.

I have the Hong Kong version,which has the same 3G frequence with At&t.
I use a At&T sim card and has 3G or H on phone and data works perfect.
For t mobile sim card you will only get edge for voice and data.
If you have any question you can email me.

Its kind of pricy,it cost me almost 700.00,but you don't have to change anything.
It depends on what carrier you use Tmobile 2G, AT&T 3G.
I love the device.you can hold it by one hand and use other hand to surf.

[Q] need to make sure im correct

I have an extra line on tmobile that is a voice and data line. I am thinking of buying a galaxy tab off craigslist, but would like to be able to occasionally use it for phone calls. correct me if I am wrong but I need to do the following:
flash via odin euro firmwear
install roto's modem switcher
install other modem.
Do i need to go the route of breaking my imei number, or will I be ok? I want to be able to use this extra line I already have, so if im correct, i will get 3g and no voice, or voice and edge. Is this correct? thanks all. If i need to break the imei, can someone pm me?

You don't need to break anything to be able making and receiving calls with other phone SIM card. Tempering with IMEI is not good thing.
On T-mobile you will have problem with data because Tmo wants you to pay extra for data services on their Tab. For that reason they check both Sim and IMEI. if IMEI belongs to the Tab sold by Tmo but Sim is not broadband type with active balance they block 3G or EDGE data traffic. It means that other phone Sim will not be very useful.
With AT&T Tab you might have better option since Tmo does not recognize it. You will not get 3G but EDGE and voice will be fine.
Personally, I DON'T like this situation but can live with it. If I really need cellular data I pay for it or use tethering from my Android phone.
Modem switcher from voice to 3G may be replaced flashing modem files via CWM provided you have proper kernel. It is a bit simpler.

To use your t-mo sim in a t-mo tab to get 3g data, you will have to break something. To get voice you will have to root your tab and flash a rom and flash a modem.

My New Nightmare Tablet

Picked up my Tablet yesterday from T-Mobile. Connected to the web etc using Wi-Fi because I had lots of software to download. Could NOT get any data with my sim card.
I am grandfathered into a data package with T-Mobile which gives me Unlimited Data for $19.99 plus a voice package. Support told me that for this tablet to work I had to upgrade to their Web Connect package for $39.95 and I would NOT have voice. [because they INSIST voice is IMPOSSIBLE with the Galaxy Tab.] [whatever]
I didn't want to agree to their upgrade because my sim works PERFECT in my Dell Streak 5 .. I believe that there is something wrong with the Gal-Tab. I kept telling them that the internet net was the same in their web connect package, it was just more expensive. They told me I was wrong. So I said .. OK make the change. They did and 12 hours later I still cannot connect.
I contacted them this morning and got them to give me my OLD $19.99 internet package and voice back ..
SO .. Any ideas ?? I even tried changing the APN on the Samsung to the same as on my streak. My streak is epc.mobile.com .. the Samsung had it as epc.tmobile.com

I had an issue with my data when I first got my tab too - the support personnel signed me up for an incorrect data package and all I got was a redirect to a Tmobile page when trying to use the browser (and no data on any other apps).
After talking to Support they changed my data package and voila, it worked.
So what's going on - unfortunately T-Mobile US filters Galaxy Tab's by IMEI. As such, they completely block it from working on any plan other than the data plan built for it. Despite the fact that the tab is technically capable of being a phone, T-Mobile will not allow it on their network.

So your telling me when I get my galaxy tab if I pop in my wifes T Mobile sim it wont work. That is truly annoying.
Instead of getting a new data package I am going to just pay the 10 a month to add mobile hot spot to her phone which will work great (maybe even faster because she has 4G on her phone)

THANKS .. I hate T-Mobile but have been with them for 8 years .. I guess I have just learned to put up with their NONSENSE !!

Since Dell Streak 5 came from AT&T Tmo does not have records and treats it as a smartphone. The same will be true for the Galaxy Tab purchased from AT&T. You will be able to get data and even voice using other Tmo Sim after reflashing proper firmware.
But since these two carriers use different frequencies for 3G you would get only EDGE.
It is hard for us to understand rational for such decisions. It seems that they are loosing Tab sales. Why do European carriers find it profitable while US not?

there is a way to get both voice+data on the tab using a standard t-mobile sim with data+voice. 1-you need to flash an European ROM to get voice and 2-then there is the issue of the IMEI which blocks the tab from accessing the web with a sim that already has data.
the second part cant really be posted as i was already removed by the mods due to rules violations, but it can be done i am using my Vibrants SIM on the tab.

Sounds like someone failed to do their homework. T-mo Tab is suppose to be data-only device and utilizes different APN's with custom modem firmware then smartphones, hence why your SIM would not work. You need to root the Tab, flash Euro firmware, then flash a custom modem. Instructions can be found in the development forum. Also, keep in mind that flashed T-Mo Tab can only get EDGE, no 3G.

That's not correct! You can get 3g data with your T-Mobile sim card with the correct modem. Just use roto-modem switcher

I think all our posts can confuse anyone.
The question was about using Tmobile smartphone Sim with the Tmobile Tab.
Let me say this: there is no way to get legitimely both voice and data on Tmo network using Tmo Sim. You can get voice without cellular data, or 3G data with different modem and separately paid broadband service Sim not the smartphone Sim.

I put my Sim card from my MyTouch 4G on the Tablet and phone works n/p but you need to flash a Euro rom! Thats it bottom line! Flash The rom and you will have phone access

How do you make phone call on the T-mobile tab with Overcome 1.4.2?

I have the USA T-mobile galaxy tab that I have successfully installed Overcome 1.4.2.
There is the option on there that you can make phone call. However, when I put my sim card in there, it cannot make any call. My sim card also has 200 mb/month of data plan.
Is there anyway that I can make call with my current tab?
Thanks.

Flash euro rom

You need to flash the correct modem file in order to make phone calls. According to Post #1 the author did not include this. There are lots of posts on how to do this.

Go here, and get the modem file
http://forum.xda-developers.com/showthread.php?t=929479
get this file listed in the OP; - modem_bell_i9000
Put phone in download mode, and load odin, then select PHONE, and drill to the location of the new modem file you just downloaded, and install it.
THEN, you need to make sure your APN settings are correct for your carrier.

Please note that currently there is no way for anyone using the T-Mobile network to use 3g and voice at the same time. It requires flashing Roto's modem switcher, which limits you to 2g, but allows voice communication.
*shrug* Decent trade off (at least for now) I use it daily.

The bell i9000 modem is for US at&t tabs to get voice and 3g.
For t-mobile tabs you will need to follow the instructions in the rotohammer modem switcher thread. There are two modems needed, one for 2g+ voice, the other for 3g data only, and an app to switch between them.

Using a T-mobile Tab and Overcome 4.0.0, is it possible to get phone/voice with an AT&T SIM and service? ....Or do I still need to switch the modem with ODIN?
I am not concerned with mobile data because I tether with a phone or use Wifi hotspots

Can't get 3G data with T-mobile Galaxy Tab?

Is it not possible to get 3G data (only) with my standard T-mobile SIM? I am a post-paid, non-contract customer with voice, data (the original data plan they offered with the G1) and texting.
I have never been able to log in with my google account using 3G data on the Tab. Wifi works fine, and voice works fine using rotohammer's switcher.
Even when I am on edge (using rotohammer's switcher), I still cannot get any data. What gives? Should I get rid of this Tab and get an AT&T one?
