Unicom just sent me a short message one day, saying that it would give me a free 4G solution. Content of short message: Dear customer: Fujian Unicom network has been fully upgraded 4.

This is Unicom's "free experience of high-speed network for hundreds of millions of users in the 4G era", which will provide 3G users with high-speed Internet service with a rate of up to 42Mbps. As long as the mobile phone terminal supports the 42Mbps network mode and is covered by the 42Mbps network, it can enjoy the Internet access rate of 42Mbps, which is comparable to the network speed of 4G.
