If you stay contained to one system you can get nearly everywhere on the map using one transfer. Know where you're starting, know where you're going and then just look for an intersection between the lines. It probably won't be the fastest route, but since you're staying in one system it won't be that expensive. In an emergency where your phone is dead, you'll always be able to get home.
