Ta tablet is a vk810 4G carrier was Verizon tablet also has a 7-in screen. The tablet is not locked can be factory reset.... Tablet is 16 GB of memory.. this is an older tablet. It does work well for what it is but I'm pretty sure it will only work with Wi-Fi. Also battery holds good charge. Charger is included in offer tablet is used but is not in that bad of shape please look at pictures if you wish to determine purchase. Thank you.....  Also forgot to mention tablet is old but it does start up very quickly for its age. Don't think any updates can be accepted on this tablet though it can do some things but it can't do all things unless you knew a way around it or if there is a walk around around it somehow maybe it can be updated. I don't know. Not for sure. Good luck! Thank you.......
