What's the difference between Apple tablet ipad4G version and wifi version?

Wifi version can only surf the internet with wifi.

Ipad4G version can not only use wifi to surf the internet, but also insert SIM card to surf the internet.

The hardware level of 1 and 4G versions is the same as that of WiFi version. The only difference is that the 4G version adds cellular data network and GPS and Glonass positioning systems.

2. Insert the 4G cards of China Mobile, China Unicom and China Telecom into the 4G full netcom iPad, which means that the 4G iPad can retrieve the 4G networks of the three major operators.

The 3.4G version of the fuselage looks exactly the same as the WiFi version, but the weight is slightly different. The 4G version weighs 444 grams, which is slightly heavier than the 437 grams of the Wi-Fi version. There are two differences in fuselage details. The 4G version of the fuselage has a plastic part on the top of the back, which is available in silver, gold and dark gray. The function is to make the built-in 4G antenna of iPad have better reception effect.

4. Compared with the WiFi version, the advantages of 4G iPad are as follows:

(1) First, with the cellular data network, iPad can completely break away from the restrictions of wireless LAN, and browse the web or send and receive emails anytime and anywhere. In addition, due to the addition of a GPS positioning system in the 4G version, the iPad can also receive GPS satellite signals for positioning without a data network.

(2) Although the cellular data function has been added to the 2)4G iPad, it still can't make phone calls or send and receive short messages. However, through the new features of iOS 8, iPad can partially replace the functions of iPhone, including answering and sending calls, sending and receiving iMessage and SMS messages, as long as iPad users also have an iPhone and use the same iCloud account.

Version 5.4G is only for users with high demand for mobile office. Most people just read books and watch videos at home for the iPad, and the 4G version is almost impossible to come in handy. And many business people need to send and receive emails, edit documents, work reports and so on. At any time, this is obviously a bit cramped on a 4-inch or 5-inch mobile phone screen. For today's iPad, the office suite has been put on the shelves, which will make mobile office more like a duck to water.
