How can a wireless router connect to the Internet outdoors?

This requires a router that supports 3G/4G wireless network cards to meet this requirement.

1. First activate the 3G/4G wireless network card service.

2. Purchase a wireless router that supports 3G/4G wireless network cards.

3. Insert the 3G/4G SIM card or U-port card into the corresponding socket of the wireless router.

4. Other settings are the same as those of a home router, such as filling in the Internet account and password correctly, turning on the wireless function, setting the wireless key, etc.

In this way, a mobile WIFI wireless network can be built to meet the needs of outdoor mobile broadband Internet access.
