Ok, today I finally give it a try to test SFOS support of dual sim.
Mainly it’s because of this:
And the harsh truth is that it works but it’s done in very very basic way which is cumbersome and as mentioned by @pitix prone to errors and leaking numbers to the third party.
Based on the above I’d like to resurrect this thread to improve the dual sim usage. In the near future I’d like to finally stop using my two phones and move totally to SFOS. I’m on Xperia 10 which except of the touch issues doesn’t show any hard bugs. Actually I must say that more of the problems are related to missing basic functionalities than real problems. Some of them are trivial, some are easy to fix with patches (I’m looking now at gallery sharing!) but there are some like dual-sim which is a stopper. And I’m not surprised @pitix asked for it. I’m totally with @Michael that he gave up on SFOS for dual sim.
But a star has been shown thanks to @pvuorela with his patch for bringing second sim card ringtone in the future. For sure there will be some work needed yet but at least we have foundation now!
Sadly there’s much work to do so SFOS will be really usable in this area. On this forum there are users that use SFOS as a business phone. I can make a bet that many of them are either using dual sim of sfos or using second phone. Either way they will also benefit from these changes.
I personally use two phones where one is of course private and second is for giving away the number everywhere. So I don’t need to care about it and I can always throw it away and get a new one.
Now, @pitix describe main functionality improvements and what he want is generally how it should be done.
@cquence shown that SFOS can always ask which sim card should be used to send message or make a call and this is great but, it should be only needed when we do a call/sms for the first time to someone or we’re manually entering the phone no/sms.
So let me summary what @pitix wanted as how I do see this based on my use case as also how I see like another person with whom I’m living is using dual sim and also how dual sim functionalities are handled by Galaxy A41/Android 12.
- contacts app, must provide option to select which sim card should be used when making calls/sms to that person. In case that the default sim card for that person is not available for any reason, a confirmation dialog should be opened to ask if the second sim card should be used this one and only time.
- messages must show which card was the destination of the message and when replying the same card must be used. Of course if the card is not present/available, handle this same way as above which is, display dialog and ask to use second card just this one time.
Of course the above and extra info/settings should be visible only and only when user has dual sim capability and both cards are present or contacts already contains card association.
So actually it all comes down to improving contacts app so it will allow to preserve sim card association.
This is a must for a dual-sim support. Because I can’t imagine always remembering which card I need to use to reply to someone or make a call.
I think this is a good topic for great feature request and improvement for SFOS and it could got as a major improvement of the system.
And by the way, we also need the option to name the sim cards (there’s a patch for this) and assign colors so this could be used in the contacts app and messages. Like for example in the Talk app that’s in the shop.
@flypig can we make feature request from this one? It seems SFOS lost at least two users because of this.
