Status of dual SIM support in XA2 phones

I've been tempted to get myself an Xperia XA2 to replace my ageing Jolla 1 (yes, still in use!), particularly because of its dual SIM functionality. But I'm confused about whether this actually works or not - release notes indicate yes, but numerous posts here on TJC suggest it doesn't... Can someone clarify; if I put a subscription 4G SIM from country A in one slot, and a PAYG SIM from country B in the other will I:

  1. be able to use "always on" 4G Internet from SIM A, while making/receiving calls on SIM B?
  2. have the option to choose which SIM card to use when making a call/sending an SMS?
  3. be able to receive calls on SIM A and SIM B simultaneously (well, not during a call of course)

Also note that the two SIMs cannot both use 4G or 3G at the same time. One will always be on 2G. This may be problematic if the 2G network in your location is poor or completely non-existent.

I cannot speak for the XA2 (mine is still running ..droid).

But in general:

ad 1. yes, you can define which SIM card should be the one to use for internet / 4G and/but this will be the ONE SIM card able to use 4G, the other will only allow 3G/2G (afaik, someone else might correct?).

ad 2. yes, but not like in ..droid where you really are asked for each call (also annoying). You may swipe top down to access event panel and select the SIM to use. But this setting is then a general one (also not perfect, but okay).

ad 3. yes, both SIMs are online (dual stand-by)

Thanks for that comment. So it is a gamble whether dual will work as on the Jolla C? I thiught if you tested everything under Android it may/should/will work???

ad 1) can't confirm: I'm using XPeria XA2 Plus Dual SIM: I can take calls on SIM2 while I'm using mobile data on SIM1

@peterleinchen i can use dual standby in android perfectly.

@jcoder oh really?? then your second sim work on 3g??? not 2G

Oh oh, so really a shownstopper if Dual SIM does not work on the XA2 (+)! Seems my XA2 will never boot Sailfish... :(

And yes afaik even under Android you only have one SIM under 4G, the other uses 3G or 2G.

@ugionaenon: Please be more precise, distinguish mobile network from mobile data. You wrote "signal is dead" and maybe only meant mobile data but @jcoder understood it as the mobile network is completely dead on that SIM, I guess.
