The LTE variant of Samsung's current mid-range 7-inch tablet, the Galaxy Tab 3 7.0, has been launched by AT&T. However, the cost of LTE connectivity is one that seems to be too high, as AT&T is asking for $300 on a two-year contract, a price that will get you the Galaxy Note 3 next month. You can also get it on AT&T's Next plan for $20 per month.
The Galaxy Tab 3 7.0 sports a 7-inch 1024×600 display, 1.2GHz dual-core processor, 1GB RAM, 3-megapixel rear camera, 1.3-megapixel front camera, 8GB of internal memory and a microSD slot, Wi-Fi, HSPA, GPS, and Bluetooth connectivity, a 4,000mAh battery, and Android 4.1.2 Jelly Bean, upgradeable to Android 4.2.2.
