Ok, lets try to find solution. What carrier do you use? And do you try another carrier sim?
I'm using NATCOM, of course i try with another sim card in other provider... Still emergency calls only
Ok, you can try to reflash your phone to U1 firmware and check, because as we know in U firmware some bands are locked.
I Did many of this model (SM-A205U BST) using Z3X, those phones work very well in my country...
So thats mean that its hardware issue. As you see your phone unlocked well and accept sim card. Software dont touch any network calibirations during unlock.

Anyway you can enter *#*#4636#*#* and try config network settings.
