The problem I'm having is I can't figure out how to get the companion app on my phone... but I guess if it doesn't work either way I won't worry about it. I was just hoping to have the sim card in the watch, but when I get phone calls I could use the phone to answer them so I can take calls in private without having to wear a bluetooth headset everywhere I go.
Yes, I would like to be able to do that too, with my TrueSmart and my now-simless Nexus4.
Getting the companion app onto your phone is not a big problem really. Use something like esFileExplorer on your TrueSmart to back up the companion ap on there into a .apk, transfer the apk to your phone one way or another (SD chip maybe involved), then sideload the companion apk into your phone.
Unfortunately, the way the Umeoux Bluetooth stack is now you still would not be able to answer incoming calls being received by your TrueSmart using your phone, right ? You could answer them on your TrueSmart via a Bluetooth headset, for privacy, but that is as close as you can get to what you want at this point.
LLPen has announced that Umeoux developers cannot fix this themselves, partly due to lack of support from MTK and that he has a meeting set up with MTK to discuss this. I would not expect too much from such a meeting, but it could be that he will have success.
