Mission Triggers

What sets off these fare missions? Proximity to where the fare might be or time? I'm only asking because playing as Franklin it seems that using sleep to jump the time ahead doesn't do anything. Yet I drove near Sandy Shores and got a phone call to pick up K-Wak. --XavierGTR (talk) 03:19, February 18, 2014 (UTC)

I think proximity and time have something to do with it, although to a limited extent (i.e., I got the call for "Got Your Back" as I happened to be driving through Strawberry at night).  I've found a good way to trigger these calls is by going into 'Sleep Mode', then turning it off after a few minutes.  Macmanius (talk) 13:48, September 16, 2014 (UTC)
