What is the short message prompting the network upgrade?

If you want to know about the upgrade of 4G packages, you can log in to Unicom Online Business Hall > Business Handling > Upgrade 4G> to check the upgrade status, or you can call the local 100 10 manual customer service to find out.

Moreover, if you have successfully handled the 4G package, you need to confirm whether there is 4G network coverage in your area. At present, China Unicom has 40 TD-LTE/LTE FDD hybrid networking test cities, and the 4G network has been covered. Moreover, in some remote areas that have not covered 4G networks for the time being, Unicom users can also use WCDMA 3G networks with a speed of up to 42M.

In addition, if your mobile phone is slow, it may also belong to the following situations:

1. Please check the network mode of your phone. If you use 3G network, you can use high-speed data services, while using 2G network (GSM network) is relatively slow.

Please check the signal strength of the mobile phone. If the signal is weak, it may be because the signal strength affects the speed of the mobile phone.

3. In addition, the speed of surfing the Internet is also related to the version supported by the mobile phone terminal.
