Make Calls With At&T Galaxy Tab

Want to make calls with your At&t Galaxy Tab? Below is a full guide on how to make calling possible on Galaxy Tab.

Please be aware that the steps given below may harm your At&t Galaxy Tab and will void your device’s warranty. We at http://www.theandroidsoul.com will not be held liable for any damage caused to your Galaxy Tab by following this guide.

Before we start first download all the files given below and save them in a separate folder.

Download the firmware P1000XWJJ4 from HERE (password: samfirmware.com)

Download the firmware P1000XXJK5 from HERE (password: samfirmware.com)

Download Odin 1.3 from HERE

Download the “P1_add_hidden.pit” from HERE

Download the modem_bell_i9000.zip from HERE and extract it.

Once you’ve downloaded all the files given above, extract them, and use the password “samfirmware.com” (without quotes) wherever needed.

Now switch off your Galaxy Tab and put it into download mode by holding “power” and “volume down” for few seconds. And then Insert your non-prepaid sim card with voice and data plan (the prepaid Sim that came with your At&t Tab won’t work)

Now run Odin and follow the steps given below (Good Luck!):

  1. Click “PIT” button and select the file “P1_add_hidden.pit” from the files you downloaded
  2. From the “P1000XWJJ4” folder select files for PDA, PHONE and CSC fields, as shown in the screenshot above (click here for bigger image).
  3. Click on Re-Partition button in the left. It should be checked.
  4. Click Start.
  5. The Tab will restart with a Russian firmware loaded .
  6. Put your Galaxy Tab in Download Mode again.
  7. And this time in Odin, UNCHECK the Re-Partition button and click RESET.
  8. Now click PDA and select the file “P1000OXAJK5.tar
  9. Click Start
  10. After the process completes your Galaxy Tab will restart
  11. Again put your Galaxy Tab in download mode
  12. Click RESET in Odin, and in the Modem field insert the file “modem.bin” which you extracted from “modem_bell_i9000.zip”
  13. Click Start. Wait until your At&t Galaxy Tab restarts.

If you’ve done everything as instructed, your Galaxy Tab should now be making calls then. Enjoy!

UPDATE – To undo this hack and restore stock AT&T firmware on your Galaxy Tab follow the instructions below:

  2. Open Odin and click RESET.
  3. Now click on PDA and select the “.tar” file that we extracted in step 1
  4. Do NOT click on Re-Partition button just keep it unchecked. And also there’s NO need of “.pit” file. You just have to select the PDA file.

    Will this hack work with a T-Mobile sim?

    Will this hack work on any 7″ Galaxy Tab?

    I am a newbie to Android, but a techie at heart. Just coming around late to this OS. So as someone about to take the plunge on a tablet I have several questions about the TAB and modifying it (restoring a feature) for voice.

    1. Currently I have an AT&T voice and grandfathered unlimited data plan on my 3 year old win mobile phone. Will that SIM work?

    2. Does this alter the SIM in way or form? Can it still be used in my phone? Swap at will?

    3. This mod not only gives me the ability to make voice calls, but also allows me to use the 3G data from my SIM? Goodbye to another monthly charge for data?

    4. Have not bought a TAB yet. Is there different versions? Do I need to buy a certain 3G version? Wondering because Costco sells them, but I think they are promoting Verizon as a data carrier.

    5. Anybody have experience using a foreign SIM, like in Hong Kong or China? I travel to Asia on business and sometimes carry two phones. Having one SIM in the tab would save me from that mess.
