ARROWS Tab Q738/SB LTE with Keyboard - Battery Issues This is an LTE model. I used it for work with a cheap SIM card, and it was comfortable because I didn't need to tether to my smartphone. However, it's an old model, so I cannot guarantee LTE connectivity. The items for sale are the main unit, AC adapter, keyboard, and dedicated pen. The battery is significantly degraded. When using it, you need to connect the AC adapter and wait a while before turning it on, otherwise, it may shut down. Please check the condition of the product in the photos. It has been upgraded from Windows 10 to 11. I will initialize it before shipping, but since it has a 7th generation CPU, I cannot guarantee that you will be able to continue using Windows 11. This item is sold as-is, with no returns accepted, so I hope you understand and are willing to purchase it. i5-7300U SSD 256GB Memory 4GB
