What does wlan + cellular mean

WLAN or WLAN + Cellular?

WLAN model

IPad uses high-speed wireless networks to connect to the Internet, such as wireless routers in your home, or wireless hotspots in coffee shops, school libraries, or airports. Wireless hotspots exist in almost every part of the world, and iPad can automatically find these hot spots.

WLAN + Cellular models

The iPad can also use high-speed cellular connection technology to help you connect to the Internet without wireless networks. In this way, you can always stay connected by train, park, or self-driving. No contract is required for purchasing WLAN + Cellular models, and services must be purchased separately. Please consult your carrier for information on the relevant tariff plan.

Data plan for iPad

To enable the cellular data network service, you need a nano-SIM card and a data plan. There are currently multiple data plans available, and most do not need to sign contracts. Contact your wireless carrier for information on obtaining the nano-SIM card and data plan.
