We all live in a time when phones have become more than just a device to call a friend on. The mobile phone has become a connection device, an entertainment platform, and a way to look up a worlds worth of knowledge.
For those of us that travel extensively, the GPS and maps feature has become invaluable. I can't imaging what it was like two decades ago when landing in a new city required a paper map and a good sense of direction. Google maps and it's trafic feature has changed how I get around in new cities, it makes traveling far easier.
What to we have to look at when we travel internationally though. I found out the hard way that my phone was not international compatible. Despite Motorola selling the Moto X as a unlocked phone, the data systems did not mesh with Australia, New Zealand or France and I didn't know this until I was in Sydney. Navigating a new city with no reference other than your sense of direction and a good memory, that is all I had to go on and somehow managed to get to my hotel.
Days were spent trying to combat this issue, it has become a required piece for me. There were many places I needed to be, and the phone was my map. So I bought a new phone. This problem has continued to this day, I have just purchased the new Nexus 5x to replace my now dying Moto X, but this doesn't ship for another month. The phone I bought in Australia has broken and that means that I had to by yet another phone to cover international travel to Korea... of course it was literally the cheapest smart phone I know of.
Just keep in mind the next time you travel, you may want to check to see if the phone you are carrying is actually as global as you think it is. Otherwise you may find yourself in a strange city that you don't speak the language and don't know your way around.
