It is not that the tablet can only use WiFi, mainly depends on the configuration of your tablet computer;
1. If only the wireless card module chip is configured, it can only connect to wireless WIFI Internet access;
2. If not only a wireless card is configured, but also a communication module (divided into mobile, telecom, Unicom, and 3G and 4G versions), you can use WIFI, and you can use mobile phone card data network to surf the Internet;
3. If in addition to the above configuration, there is also an OTG interface, you can support a wireless network card to connect to the Internet (Note: wireless network card and wireless network card is not the same hardware, the specific does not say, there are often netizens wrong, the meaning and function of the word difference is very different, not a thing). Not much to say, but the general ordinary tablet, built-in wireless card is standard, that is, wireless WIFI connection is standard. The other depends on the specific configuration you buy, and the high configuration price is also high. It depends on what you actually need.
