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.

People are trying to flash modems of Tmobile tab to enable 3g+voice.. There are so many assumptions.. MAYBE information are programed WITHIN the SIMS card... that so you can't make it work via flashing modems.
Just wondering....

i noticed that after flashing roto's 2g modem (only way to have voice calling as of now) i still could not make a call, a man would come on immediately saying "this phone cannot place outgoing calls"...something like that.
so i tried my g2 simcard and it worked perfectly. (t-mobile tab btw) so, even with slow speeds, it seems t-mo has it locked down by disabling the sim they give you.
comparing my g2's sim to the GT sim, seems that there are more contact points on the phones sim than there are on the tabs

First of all - "Not another TMo US 3G+Voice thread!". Please, no more!!!
I'm guessing here, but you're using a SIM you got with the Tab which has a webconnect plan? As far as I'm aware, these plans have no voice - so it's not the SIM, it's the plan it is linked to!

I bought a VS980 (The Verizon G2) because they come unlocked and it was cheapest. I use Net10. The sim card works within the phone, however it constantly shows that i am roaming, i dont get hspa+ (4g) anymore. Also it shows the sim card icon with a question mark on it. Could i possibly flash AT&T firmware onto it to fix that? I mean, what could i do? What specific things would i need to change?
Thanks a lot!

i also face same problem always showing roming icon when i use any gsm sim card on it...
I have the VS980 and it works great on T-Mobile, I get GPRS, EDGE, 3G, HSPA+, and LTE. I never tried it with AT&T or another GSM provider though.
When you use the stock ROM it will have issues like you listed, however if you install another ROM it should work fine. I believe I was running Malladus 4.2.2 at the time which removed the ? icon, and I didn't have to enter any APN info. I also ran it when on a 4.4 AOSP ROM.
so do i have to downgrade the bootloader or what? I'm actually trying to get a verizon vs980 on cricket (aio wireless/at&t network) and can only get H speeds. not bad and i can stream HQ youtube videos without buffering but would like faster. any input?
I met this problem, too. Is there any solution so that I can get my 4G back?
Please help.
Hi, I cant seem to switch my phone to 4g / LTE. I've tried the various *# hacks like LTE only, but i only get 'Not supported'. Anyone else experiencing this? I was using 4g and getting 4g speeds on my N5. The phone was previously locked and I unlocked it straight away after receiving it.
The software version is D80210g-234-30
Anyone?
im also interested on how to fix this. anyone?
Turns out it was just a problem with the sim / network I was using (Tesco (o2)). When I tried with another 4g sim the options for LTE showed just fine

It was a problem with my network provider, nothing to do with the phone. Try another 4g sim from another network and see if you get 4g / LTE
I contacted LG today about the 4G issues that many experience and I thought I should share the official response:
Many Thanks for your email regarding your LG G2, I am sorry to hear you are experiencing problems in receiving 4G.
Can I just ask whom your network provider is? All main UK network providers bar a couple are receiving 4G via our handset, there are only a few 4G networks at the moment who are yet to approve the software on the G2. Please note it is not a limitation of the handset but is network dependent
The above will also explain why some other people in the area are getting it, their networks are almost certainly among those whom have approved the software on the G2 handset.
I look forward to your earliest response with the network provider, once received we should be able to clarify this for you.

Hi, I have recently upgraded my phone to a sim free LG G2 also, and in doing so spoke to Tesco Mobile about receiving a new 4G sim to match my upgraded tariff.
This has all been put in place but I still have no ability to select LTE in the preferred network section. New APN settings were sent out by Tesco but this didnt make any additional setting options available, has anyone got any more info on this issue or advice?

You probably also have an non-EUR software version installed on your G2. Where did you buy it from?
If the above stands, the solution is to flash the EUR software version, although I haven't as I do not really need 4G for the time being. 3G is completely fine.

The handset was purchased from Expansys in the UK and the software is version D80220b-EUR-XX.
So I would not have expected that this issue would come up, it seems to be a unique blend of Tesco(UK) carrier settings and the handset software.
I won't be flashing any new ROM as a solution for a problem which sits with the carrier. Though I am keen to hear if any other users have found an alternative work around.

You already have a EUR software version, so you do not have to flash.
There is a problem with some carriers in the UK not approving the G2 4G software as I have stated above.
Had the same problem.
Changed the SIM for a new one (still labelled 3G 128k) and 4G is fine now (stock JB D802 SIM free).
My previous SIM was almost from the turn of the century (cut to fit microSIM)
I'm having the same problem, no LTE option, here's a solution:
Enter Android test menu by dialing *#*#4636#*#*
Go to Phone Information ... Set preffered network type ... f.e. to LTE/GSM/WCDMA ... if LTE is available, my phone switches to LTE ( showing 4G ) immediately without restarting.
This is what I did

Hi, i recently buy an used nexus 4 in ebay, simply for nostalgia, so, i´m in Mexico, the nexus 4 that i had 3 year ago, was unlocked, so, i supose this too, when arrive, i connect to wifi immediately without any sim inside, the cellphone request for one upgrade, i accept, after that, i put my sim from Virgin Mobile and the nexus only showed " no simcard inside, only emergency calls.... y try with other carrier, weex mexico (virgin and weex work in Movistar, they are OMV) and the same all.... finally y put a sim from at&t mexico, nothing... with the sim (att) inside, i downgrade to android 4.4.4, when woke up, the nexus 4 with the same result, No simcard, so, the cellphone wasn´t detecting any simcard, after that, it request for the next upgrade, lollipop 5.0.1 that i accept, but in this chance, the nexus with the simcard from ATT showing signal¡¡¡¡¡ the cellphone was working at 100%, i made a couple calls, without problems.
But, i try with the other 2 simcards, and it doesnt detecting, simply show again No simcard, emergency only, so i switch back my Att sim and this is detecting without problems....
I install a rom named Pure Nexus, waiting for work, but the same, only with ATT simcard work, so i downgrade again to 4.4.4 but in this chance with other simcard differnt from AT&T, Virgin mobile.... but nothing, nexus 4 is not detecting any other simcard than at&t¡¡¡¡¡¡
What can i try? could be a nexus 4 locked only for one carrier or what? in google dont appear in blacklist, the imei is good nor corrupted... could be the sim holding?
try going back to stock using the nexus 4 toolkit,then root, and try one of the hybrid models LTE enabler or download the 107-3, if that doesnt work also, then it might be defective.

use this to go back to stock
http://www.wugfresh.com/nrt/
you will get android 5.1.1, you can also install custom recovery and root using it.
then if the sims doesnt work, change the modem using the LTE Enabler you can get it from the Play Store.
it has the modem until version 104-33, but im using another one the 107-33 that i got from
https://drive.google.com/open?id=0B77BTW0zStYCZmpPR0xTaWE5OUU
104 33 and 107 33 are hybrid modems, but you can also install stock modems,
the modem is the one that allows you to make calls and use the data channel in your phone
hope that makes sense, let me know how it goes. regards.

well, i flash EnableNexus4LTE.zip and LTEhybrid33-84 without good news, i have the same issue, only at&t mexico sim is detected and the others no, well, i´m now with 4G LTE but only working in at&t
i don´t know what other things trying in the nexus, seem like only prefer at&t sim and no one else.
Adding information, i have sims from cricket USA and t-mobile USA, i know is not supported in México, but it will be for try to get something like: Sim not activated... or invalid sim, but other different from my nightmare: NO sim, please insert....

I´ll auto answer... after a lot off attempts, i found the problem is the sim reader, like i posted before, only working with at&t Mexico sim, so, I watch the thickness of this was little bit smaller than others, my "strategy" was try to imitate the fact that at&t sim is making contact gently on pins, i take a 3in1 simcard, and i put the nano sim in micro sim adapter (included in the sim) but not in all (i don know exactly the words in english), so by this waya the nano sim standing on a little bit from microsim adapter.
when i insert the sim by this way an my nexus, and turn on, the cellphone recognize inmediatly the sim, so i found the key of this problem, like i said, the problem here is the sim reader, because, a normal and good sim reader not need this tricks to get signal.......

you should be able to select "LTE/GSM Auto" that way the phone will switch to GSM when needed.
and the option is only visible under *#*#4636#*#* menu, also, we have to switch to LTE/GSM auto, if the phone is restarted. there is a way to make it persistent, but I haven't tried. i'm fine with it since i don't restart the phone too often.
hope this helps, regards.
