A:AnswerThis is the Wifi model. The Wifi is built into the device. If by chip you mean SIM card to make it work with a wireless carrier such as AT&T or TMobile, it doesn’t have that capability. You’ll want the Wifi+cellular version if that were the case.
A:AnswerNo. You need an iPad that has cellular, like Verizon, ATT&T for example. Then you absolutely can use with Apple CarPlay. Apple's Maps app is better than Google Maps on Apple CarPlay, in my opinion.
A:AnswerIf your smartphone has hotspot capabilities, you can turn your hotspot on and connect to your phone's WiFi from the tablet (search for WiFi networks). But note, it will use your smartphone's data. You can also contact a wireless service provider to get a wireless plan specifically for your iPad.
A:AnswerGo to Apple.com and at the top right of the page is a small magnifying glass icon. Tap it and type instructions for ipad. You will have several choices.
