I'm using an S21 5G and want to attach it to a private 5G SA network. First, the phone can detect the network and attach but after a while(some minutes) is dropped off. I already used this phone in a public None-SA network and there is no problem but it's not working in SA mode. we tested another phone from other brands and it also working in our private network without any problem.
I'll appreciate it if you support and let me know your comments.
