The 3G variant of the Samsung Galaxy Tab 10.1 GT-P7500 can now be hacked to enable voice calls. Having a tablet that can also make calls is a great way of optimizing usage so that you don’t have to switch devices to keep in touch with the people important to you. Since the Galaxy Tab 10.1 came with a 3G variant, it has always been theoretically possible to enable phone call functionality. Luckily, XDA Developers member almaqdad figured out how to make this a reality, so you can now try it for yourself.

This hack can only be applied to certain ROMs, though. Specifically, the stock Samsung ROM for Android 4.0.4 Ice Cream Sandwich (ICS), the Android 4.1 Jelly Bean-based CyanogenMod 10 (CM10) ROM, the ICS-based CyanogenMod 9 ROM, and the AOKP ROM.

This guide shows you how to enable voice calls on the Galaxy Tab 10.1 P7500.
