Some websites can’t be displayed on the phone ? That could be a DNS issue.
What is DNS ? The domain name system is a service of the Internet, which can be imagined as a postman or a telephonist.
If you set the most suitable domain name system, the Internet speed will be the best. Internet low latency can prevent the network from getting stuck.
