LTE or 3G for data and voice on one SIM and 3G voice on the other SIM?

[aldente]

Hello,

I am wondering if any recent Sony Xperia Dual SIM models support the use of one SIM with LTE or 3G for data and voice and the other SIM with 3G for voice in dual active mode, Xperia 10 Plus Dual SIM in particular.  The user manuals do not seem to mention this.  Xperia Z5 Dual SIM is my favourite that I have been using, but the only downside for me is that Z5 Dual SIM is forced to have 2G voice on the other SIM if one SIM is set to use LTE/3G for data/voice. This puts me in an awkward postion when I go to a country where 2G GSM has been terminated. Thank you in advance.
