Make Calls Using Your T-Mobile Galaxy Tab

As many of you may already know, the U.S version of the Samsung Galaxy Tab was stripped of its calling abilities. The geniuses over at XDA weren’t going to have their European brothers have the ability to make  calls and not them, so they managed to hack the Galaxy Tab and enable the phone functionality. Currently, the hack only works for the T-Mobile USA Galaxy Tab and requires quite a bit of modifying. We’re pretty sure there will be an easier procedure in the near future, so keep your eyes peeled. For the dare-devils out there, hit the link below for the full instructions to get calling features working on your Galaxy Tab. Let us know in the comments if you successfully get the hack working.

    man, the xda guys are absolutely incredible.

    • yourboyfriendthinksimhot

      Um… or u can download TANGO and use it to make phone calls… AND video calls to ANY Android or iPhone…

      I’m not impressed by this “discovery”

  • TmoHax

    That was the first thing I said when I saw the tab “can I call on that? Cause I would look so cool if I could.”

  • Will

    Ok, if it works, I think that I will get one. It was really the only deal breaker for me.

  • Mike

    I would love to see someone actually using that to make a phone call. That thing is huge. It would look like some kid using Andre the Giant’s Android device.

    • Yyevo

      Ever hear of Bluetooth?

      • Doug

        exactly, because as far as i know this thing doesn’t have a proper earpiece. so its either going to be blue tooth or speakerphone

  • http://www.suffolk757.com Hilton

    Wow, deal breaker unbroken. If I wasn’t waiting for the Nexus S…

    • briannn

      You didn’t hear the nexus s is not coming out . They are scrapping it to make a dual core phone . In early 2011 . They are trying to set the bar in android phone again . Search google for it I forgot where i read it but the article is all over the web

      • 2FR35H

        False information you are giving. They scrapped the ORIGINAL Nexus S to insert a dual core that is still planned to be released this year. The other Dual core with planned release in 2011 is a absolutely different device.

        • somebody

          ^^^^^^^^

          anyone second this

        • http://google.com 5!n7 is my name upsidedown

          im sorrry, but i cant!

        • remixfa

          lol, your half right..

          they are scrapping the original nexus S for the dual core nexus S, but it wont be released until Q1. They havent even optimized gingerbread for dual core use yet, thats what the hold up is. Sammy wont release the phone until its fully operational.. which is a good thing.

  • Wilma Flintstone

    Xda rocks. Now if they can get MeeGo on that thing, that make me giddy with glee.

  • Cellphone Chris

    PLEASE NOTE THAT THIS HACK WILL DISABLE 3G! At this time, per the linked thread, users are only getting data connectivity on EDGE after this mod. I suggest you give it a little more time for the guys at XDA to get a complete solution. I have a Galaxy Tab en route from T-Mobile now without contract and plan to tether it for data.

  • Jonah

    I’m confused. If you have a DATA ONLY plan for the Tab, how is it possible to make voice calls? Don’t you have to purchase a voice plan (whenever minutes, etc) as well? How are you being charged for voice call minutes if you only have data plan?

    • Now_onTMO

      Ummm google voice? Skype?

    • UMA Fan

      Simple.

      You just stick a SIM card in there that’s already activated with a Voice/Data plan for a phone.

      Even after you activate the TAB on a data only plan, Customer Care will change it to a voice/data plan if you ask them too.

    my friend was only able to use his current data enabled SIM on the Tab for about 2 hours before it started giving him a message about needing a correct data plan. When we called up they said that he needed to have a Tablet plan to use data services. How can it tell, IMEI or Device name? Isn’t it just an Android device, so shouldn’t Android data work just fine? What gives?

    • Cellphone Chris

      Goes by IMEI – For instance, I have an HD2 which uses a 24.99/mo unlimited data plan. I’m running Android Froyo on it however with no need for a $30 Android Data plan, because for all the network knows, I’m on an HD2. Last week I lose my phone and buy a G2 to use while I wait on my insurance replacement. I make no changes to my plan, and guess what, NO DATA! The CSR tells me I need the $30 Android plan to make it work. Of course, I just waited it out and used wifi while I waited a couple days for another HD2. Once my Galaxy Tab arrives next week, I’m just going to tether it to the HD2 and continue to use my 24.99 data indirectly.

      • Cellphone Chris

        *Wifi tether, btw…

        • chewy

          That sounds horribly off. Any data plan past the old $20 Blackberry one (which is EDGE only) works with Android phones. You do not need a $30 “Android plan” if you already have the $25 one. I’ve used my supposed “Android plan” for data on my unlocked iPhone and it works fine. Call Tmo and at the prompt say “Loyalty” and get your $25 unlimited data plan back. It’s only called “android” in their system, data is data. The local Tmo tried the same thing and “upgraded” my plan without telling me, I talked to Tmo Loyalty and had them change it back.

          Local CSRs and the CSRs you get from the normal Customer Care prompts have no clue generally.

        • Dysphoria

          I can’t help but think that access to certain “x-only” features related to the OS would be on that – servers for unique applications or download markets. And Blackberries definitely need specific support, especially if someone is using an Enterprise server. if you’ve got an unlocked iPhone, it should work the other way around – because T-Mo doesn’t actively support iPhone on their servers, if you’re getting access to anything, you’re getting access through the generic web server, which anyone could theoretically access from their phone.

          My HD2 ran pretty much everything fine except for a few core apps while I was still on Android web, but the core apps would only function after switching to their Windows web.

  • Sweetchili

    The Tab doesn’t use cellphone web like Android web. Its the webconnect that the rocket/netbook uses. It’s configured differently. The system knows what imei & data soc you are using.

    The first system aka Sampson, will not notify you changed your device for up to an hour. Once Sampson notices the change and makes changes the switch contacts Sampson every two to 48hrs to see if there are any changes made to the account. If the switch see a change in Sampson it the makes the lib changes you would notice on your phone. pda tech reps use a system called the iHLR to make live changes in the switch. It’s pretty cool.

    • CSRrep

      Tipsofme, I’m sure you meant “samson” ;) All csr & tech reps should have access to the ihlr.

    Can the XDA group work there magic and get the Tablet version of ThinkFree Office for the Vibrant?

    It tabs at the top of an excel file and is so much easier to use.

    The build version is: 101018(R117831)/sstablet (trunk)

    Can I get pointed in the right direction if this is not the right place?

    • http://TMONEWS Bobkeschlob

      I could use the correct version of “THEIR.” My wife is a teacher too.. OUCH!

  • Robertthegreat2

    You download tango app in the droid market and you can make phone calls with your tablet

    • Wuiliuw

      I downloaded Tango but still can’t make a call but can only text. What am I missing? thx.

  • Jtc442

    I hacked mine, got the phone function, yes, only on edge unless i flash the tmo radio back, but works awesome. I went and purchased a simple mobile sim, unlimited everything, 60.00 bucks a month!

    • Nebajide

      Show me how did it, Sir. I want the Galaxy Tab, but with phone capabilities. Thanks.

  • Zealia

    This is probably a stupid question but, after you hack the tab to use phone capabilities what is that working off of? as in is it using data to work the phone cause you dont pay for minutes so i am a little confused how it all works???

      You have to have a voice plan in order to use it.  No free calling.
