Hi. I have an A54 samsung and after the latest android update, it can not connect to the mkbile data network anymore. Even when it shows it is 5G, it can not open websites, but 90% of time it is on Edge. It is so frustrating, since I can not even buy bus tickets when I am out. Although, it does not have any problem with WiFi. I've tried every solution and check every thing. It seems that it is just a problem with the phone.
