im using sm-n935L (samsung note fan edition -Korean) (carrier-LG U+) .now im in srilanka and srilankan sim cards not detecting to phone ..what i can do for that.
Device is incompatible with MM bands in Sri Lanka (probably software lock, not hardware). Pretty casual stuff. Modern phones support almost all frequencies, so try a reboot or reset. Make sure your phone is unlocked though, if it's locked then you can't use it.
