No, this tablet does not even have the ability to connect to Wireless phone service (2G, 3G, or 4G). (so cell service is certainly not required)
You can also use this tablet without having a Wi-fi connection. HOWEVER, much of the content that this device would give you access to (Netflix, Youtube, all the Google Play Apps, free & otherwise) requires a wi-fi data connection.
NOTE: Many of the Apps available to this device only require that you connect (with wifi) to download them, and once downloaded, can be used (played, etc) without a data connection.
No, you do not have to be married to use the tablet either, although if you are, I recommend not ignoring your wife while using this tablet.
You can play selected games, and there are quite a few, without connections. To access Google, you need Wi-Fi, and I found it very easy to connect.
Hi. No u don't need cell service. You do need wifi in order to use it. Also to go on the play store. If u do download some games with wifi. U could play some games offline. Hope this helps.
