Does Xperia XZ support 4G & 3G dual standby?

[Oldpete]

If Sim 1 is on 4G LTE, will Sim 2 support 3G standby. I have used older model (Xperia M5 Dual) before, it only supports 4G LTE and 2G.

If you select for sim #1 for preferably 4G(LTE),or strictly 4G, then Sim#2 will be on 3G or preferably 3G.and 2G...From  my experience if 3G signal is weak it will immediately go to 2G.
