Safari not working with Mobile data
I have an iPhone 12 Pro, using iOS 14.5 (latest). I have unlimited mobile data which is ON. Roaming is ON. Safari is ON for using mobile data but when I am out of the house and without WiFi, I cannot get any websites - only the message that Safari cannot connect to the server. I don’t think I am doing anything different to what I did with previous iPhones (4, 6 and 8) and I did not have this problem with them.
I have gone through everything in Settings in case there is something new which I have overlooked but to no avail. Anyone have any ideas?
