One of the major differences between a cellular iPad and a WiFi-only iPad is GPS. Only cellular iPads have GPS, which can provide you with accurate location tracking services like Apple Maps.
Cellular iPads are great for boosting productivity if you use the iPad as a professional device. You can attend meetings, answer calls and download files from anywhere.
Cellular data is better
Public Wi-Fi connections are arguably not as secure as mobile data. Therefore, if you work outside and often use unsecured Wi-Fi connections, buying a cellular iPad is better.
With a cellular iPad, you don’t have to rely on a Wi-Fi network to play games on your iPad. You can easily play cloud games and online games while commuting using a cellular iPad.
