If I hail a taxi cab, by butt-dialing their line, they are extremely unlikely to interpret it as a crank call.

At least, the kind of crank call where they'd need to send a cab.

Either way, please lock your devices.

If you dial a taxi you need to provide your pickup place and name usually, accidentally dialing it won't make a car get to you. Not sure that's what you mean.
