The download speed of my Unicom mobile phone card has reached 35 megabytes per second. Is it a 4 G network or a 5 G network?

If the download speed of your Unicom mobile phone card reaches 35 megabytes per second, then this may be the speed of 4G network, not the speed of 5G network.

It should be noted that the speed of the mobile phone card does not necessarily correspond to the network standard. In fact, the speed of mobile phone cards may be affected by many factors, such as signal strength, network load, mobile phone hardware performance and so on. Therefore, although your mobile phone card has reached the speed limit of 4G network, it is still possible to test it under 5G network.

In addition, China Unicom has launched a 5G network service. If your area has covered the 5G network and your mobile phone supports the 5G network, you can try to start the 5G network service and test the speed of your mobile phone card. If the speed of your mobile phone card has improved and reached the speed range of 5G network, then you can confirm that it is a 5G network.
