I have had the 6 since launch and just decided to pick up a 6+ to both use and be my iPad Mini replacement. What is the best way to use the two devices if I will be swapping SIMs frequently? Set up one the main number with iMessage and the other without, etc. In a perfect world I would love to be able to receive messages and such on the 6+ while using the 6 as my main phone (whether through continuity or iMessage). Then when I switch my SIM into the 6+ just have it work as it should and am not concerned with messaging back to the 6 while I am using the 6+ as my main phone. I know the above is a little confusing, but is any of that possible or does the fact that the 6+ is a phone make what I am trying to do not completely possible. Thanks for any thoughts/input.
