iPhone 12 Pro Max won’t connect to 4G

Hi all.
I’m having issues with my iPhone 12 Pro Max connecting to 4G. It was working fine up until an hour or so ago when it just went to 3G.
I have tried airplane mode, turning the phone off and on, reset network settings and also checked the network coverage map to make sure there isn’t a problem.
I don’t know else I can try?
Thanks in advance!
