I guess you move often. Good luck however explaining to the CP why you could not make a 2 hour call out to EWR with a address on record 80 mi,es away in PA and then 3 days later could not make a 2 hour call out to JFK. Best to only use a cell phone if you are going to claim you were traveling ect.. Another good reason not to have a home phone. Keep in mind one of your fellow pilots is going to have to cover the trip that perhaps should have been yours.
