Recently during my trip to Istanbul and Gallipoli (Turkey) I found myself in a country which only spoke English when there was money involved. Wanting to learn more about the country, the places I found myself and the food I was eating I decided to try out my Android smartphone, a Samsung Galaxy Ace 2.
Some things I found especially useful when out of the country include:
Taking my phone charger with a local power adapter and portable charger.Having your phone last more than an hour is kinda important to help stay on top of whats going on. Being able to plug your phone in at cafes and hotels is a good thing especially as this is where you normally find free WiFi. For those moments when you're running out of juice a portable charger can be a lifesaver. I ended up buying a solar powered charger as it could be charged while I was in the middle of nowhere at Anzac Cove, Gallipoli.
Google Maps with Offline Maps.While you're in the hotel make sure you take advantage of free WiFi and download local maps to your device. Making the area available offline means you can use the GPS and maps to know where you are and where you're going.
Speaking of where you're going, make sure to bookmark the places you're trying to get to while you're still in the hotel, that way you can quickly see how far away you are.
