25. Download Travel Apps While You're Still At Home
Travel apps can make all the difference when it comes to making your trip easier. Download your airline's app so you can check in on your phone and see any flight changes real-time. Uber can help you get taxi-like services on demand, and then Citymapper is like Google Maps but can be used offline, so it doesn't eat away at your data. Other suggestions are WhatsApp, which lets you call and text abroad for free, and PackPoint lets you know what to pack depending on where you're going and what the weather is like. Genius!
