One good thing with phone PPR is that someone is supposed to answer, and to give you useful information (Fuel available, tie downs available, café open etc.). In France, airfields are generally not PPR, unmanned, sometimes completely deserted, and getting useful information for your preparation is difficult (I'm sure some of them would have more traffic if they were PPR, as you're not going to choose a destination you don't know enough about).
With a bluetooth headset, you can get a phone PPR while airborne. You can also order your taxi once you know with a good precision your time of landing. You can get your clearance to enter controlled airspace under IFR while ready to depart at an unmanned airfield. It's a really a good feature
