Thanks both! I am a little confused here -- if the problem is SA/NSA switching, then so long as we turn off either SA or NSA it may help?
But I understand you both suggest turning off SA instead of NSA - isn't NSA the older, slower network? How about if we turn off NSA instead?
Yes, problem is with SA vs NSA switching.
If you turn off NSA, your phone will connect to SA only. If no SA antenna nearby, you basically have no Internet connection..... I tried just now, disabled NSA. No Internet connection cos no SA antenna nearby....
So I'm using *#2263# to turn off SA and I get 5G on NSA only. Which works, so far, traveling around sg no more Total network drop or data drops.
Old antenna, slower 5G speed than SA, but at least much stable and less random total network loss...
