Ipad is divided into wifi version and 4g version. What's the difference?

the 4g version can be directly inserted into the card, and the WiFi version can only be connected to the network with WiFi.

The specific difference between them:

Version p>1.4G has the same hardware level as WiFi version, such as screen, processor, fingerprint, etc. The only difference is that the 4G version adds cellular data network and GPS and Glonass positioning systems.

2. plug the 4G cards of China mobile, China Unicom and China telecom into the full netcom version of iPad Air2, that is, the iPad with model A1567, and the 4G networks of the three major operators can be retrieved.

in other words, the data cards of the three major operators can activate the full netcom iPad Air2 and can normally use 4G.

3. Compared with the WiFi version, the 4G version of iPad has the following advantages:

(1) First, with the cellular data network, iPad can completely break away from the restrictions of wireless local area network, browse the web or send and receive emails anytime and anywhere. In addition, because the 4G version adds a GPS positioning system, iPad can also receive GPS satellite signal positioning without data network.

(2) Although the 4G version of iPad adds cellular data function, it still can't make phone calls or send and receive SMS messages. However, with the new function of iOS 8, as long as iPad users also have an iPhone with the same iCloud account, iPad can partially replace iPhone functions, including making and receiving phone calls, sending and receiving iMessage and SMS text messages.
