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:

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

Thanks!

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)

Dual sim dual standby still not working with the new 3.1 update. Single sim in slot 1 is OK but try using 4g with 3g and both sim cards lose connectivity. No issues with android prior to installing sailfishOS. For a phone you'd think getting sim cards to work reliably and hassle-free would be a priority. Thumbs up for fixing the fingerprint sensor though.

No issue here, using 3.0.3. I can freely switch between SIMs, both for voice/sms and for data and I can use SIM1 for voice and SIM2 for data or the other way around without issues. Incoming calls and messages works for both SIMs regardless which SIM is active.

testing on Android dual sim worked perfectly, since sailfishx I can only have one sim active, as it will dissable.second sim. sometimes I need to put second sime in my old X to get it to register again.

@GD, @melvinzt: that seems to be an issue with your individual setups then. Something in the combination of Sailfish and your SIM-cards/operators does not work. There are other people, more than me, that has it working, so you should provide more info to help Jolla narrow the issue down.

My 4g sim card has no voice or SMS service only a data connection. Maybe that's causing problems. I use the 3g sim for calling and messaging because it's cheaper than 4g. Still my opinion is that it shouldn't even be an issue at this stage of development. Considering android worked without a hiccup, there seems to be a basic flaw within the sailfish operation system if sim cards can't even connect. Not sure what kind of technical info I could provide that might help. Was there an app that logged connection data?

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

ugionaenon ( 2019-06-08 17:23:59 +0200 )edit

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.

peterleinchen ( 2019-06-08 19:27:11 +0200 )edit

@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.
