If you're lost in a foreign city, a smartphone can be a lifesaver.
Of course, it has to be with battery and internet! HAHAHA
Just open the google map, tap in the address and it will sends you on your way. But, It is possible to run up a huge bill without consciously using your smartphone, because many have applications that automatically search for online updates whenever the device is on. In other words, when you use another mobile network to access the internet on your phone while still being billed by your normal provider. It can be pricey, so many people turn their data roaming off while they are abroad. Some even leave their phone at home. It is impossible for me to leave my phone behind, i need it to survive. LOL!
