1. Please check the network mode of your phone. If you use 4G/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.

4. Please clear the phone cache to free up space.

If this situation still occurs, please contact the local Unicom manual customer service for feedback.
