That is actually not true.

You dont need DSFA for that, and for most dual sim phones on the market both sims will remain available for calls and sms while using internet. Yes, most newer dual sim standby phones can use internet on one sim and still receive calls and sms on both sims. That is the case for all MT6575 and MT6577 based phones, and some Qualcom phones as well (U8950D for sure).

For those phones, the only thing that will make a sim go offline, is a active call on the other sim.

The only thing that DSFA really adds, is that you get calls (like call waiting) then you talk on the other line. Don't get me wrong, it is a nice feature to never miss a call, but then again it is not that often that you receive calls on both lines, at the same time.
