The villa owner with a weekend 4x4: desert recovery is a different trade
What you do before the recovery arrives decides how easy it is. Stop digging the moment the wheels spin freely; every further attempt buries the chassis deeper. Drop tyre pressures hard if you have not already. Note a precise location, a dropped pin from your phone's map app is the single most useful thing you can send, along with which track or gate you entered from and a photo showing how deep the car sits. Stay with the vehicle. A car is visible from a distance in open desert; a person walking out in summer heat is in far more danger than a person waiting in shade beside a stuck car.
For the villa household that does this most weekends, the honest advice is to build the relationship before the emergency. Vendors who do desert work advertise it specifically, and the same-vendor rebook in tamam means the recovery driver who pulled you out of Fossil Rock in March, and already knows your car and your usual area, is one tap away in April. Going out in convoy with at least one other 4x4 remains the rule that makes most recoveries unnecessary in the first place.
