If you have recently purchased a Samsung Galaxy Tab on AT&T, Rogers or Bell and wished that you could use it to make voice calls, you are in luck. XDA member ClubTech has released a method that works on these carriers that will allow you to bring voice calling to your tablet. Unfortunately this method will not work on T-Mobile due to its IMEI block (you'll need this method for that), and will not work on CDMA carriers, either, for the semi-obvious reasons. (Hint: They're not GSM.) Hit the source link for full download links and instructions to bring voice calling to your tablet! XDA Developers]
