To connect a 4G or 5G cellular data network, you must have a wireless wide area network (WWAN) module and a nano-SIM card installed. The nano-SIM card might come with your computer by countries or regions. If no nano-SIM card is shipped, you will need to purchase one from authorized service carriers.
Depending on the model, your computer might have no WWAN module installed.
The 4G or 5G cellular service is provided by authorized mobile service carriers in some countries or regions. You must have a cellular plan from a service carrier to connect to the cellular network. The cellular data plan might vary by location.
Network connection speeds might also vary by location, environment, network conditions and other factors.
