dual sim support
In Developed countries, dual-sim phones are a common thing. I have two Lennovo phones with dual sim support, and I was hoping the it is possible to have this feature if it's not a pain.
+1. Being able to choose SIM for SMS and calls would be REALLY useful. I have a personal line and a business line. Currently I can only use Join with the personal line which is most annoying! The google messaging app allows you to switch SIM by holding down on the send button (same as bringing up the subject box). It would be great if Join could either mimic this, or even better just have some obvious selctor, or even 2x send buttons.
I'm in a similar situation right now, I have to manage two independent mobile numbers (different countries in my case) and this makes the desktop sms feature a lot more difficult to use, I haven't encountered any alternatives that support dual sim desktop sms either though.
I'd recommend a symbol that lets you switch between the first and second sim card in case there is more than one.
