When do I need Wifi?
When you first turn on your tablet you will be prompted to connect to Wifi. This is so you can login to your account. You will only need to log out if you have multiple accounts, are using one account on multiple devices, or for troubleshooting purposes.
Periodically the tablet will need to connect to Wifi to receive game updates and for the play data to sync and appear in the Parent Hub.
Can I use this without Wifi?
As long as you are logged in, your child can play without WiFi - in the car, train, plane, etc. Their data will remain on the tablet until you are connected to WiFi again. When you're back on WiFi, you'll be able to sync your data then view your child's progress and activity in your Hub.
