Here are 10 things you need to know to save some money and get the most out of your smartphone when traveling internationally. Global roaming functionality used to be an extra feature that users would have to manually opt into using for an additional fee. This has now changed and many cell phone service providers such as Verizon, AT&T, and T-Mobile now activate international texting, calling, and data features automatically as soon as the handset is used in a foreign country. This activation usually incurs a pricey fee that’s recharged on a daily basis and can get very expensive if you’re planning to travel for a long period of time. Metro PCS’ World Calling is another popular service many people use for making international phone calls while traveling. Having a locked phone means that it can only be used on one specific provider’s cellular network and this means that you won’t be able to use that phone in a country where that network doesn’t exist. If your phone is unlocked, you can use it on other cellular networks both in your home country and abroad. SIM card rental is available in most regions and can be done at specialized stores in major airports and at cell phone company branches. Renting a SIM card is generally much cheaper than paying for an international roaming service, especially for those planning to travel abroad for several days or weeks. These Wi-Fi devices are about the size of a deck of cards and can be carried in your pocket or handbag. They broadcast a strong Wi-Fi signal to which you can connect your smartphone and other devices while traveling. Such devices can usually be rented at airports and in telephone service provider stores. Some tourist information buildings also offer them to travelers. To prevent you from ending up with a dead phone while on the road, some good advice for smartphone owners is to invest in a good quality battery pack that can hold a significant amount of power. These typically feature at least one USB slot which can be used to recharge your smartphone, tablet, or other electronic accessories. A quality battery pack is a solid addition to any travel tech kit. A USB port in an adapter will save you a lot of space when packing as USB cables generally take up much less room than cables with wall plugs on one end. USB charging cables will also likely work with more than one of your devices so you won’t have to bring a separate cable for everything you own. Because of this, it’s a good idea to download some content before you travel so you have something to keep you entertained during your flight or after you arrive in a foreign country. The Netflix smartphone app lets you download many of its movies and TV shows, while the official YouTube apps have the ability to download your favorite videos if you’re a YouTube Premium subscriber. Other good options for offline media include the first-party digital stores for iOS, Android, and Windows 10 devices, all of which allow for the downloading of movies, songs, podcasts, and TV series. Spotify is another good choice for podcast downloads and music downloads, though you’ll need a Spotify Premium membership to download songs for offline listening. Some airports do offer free Wi-Fi but many don’t. The airport’s Wi-Fi shouldn’t be relied upon either, as once you leave the airport and get in a train, bus, taxi, or Uber, your smartphone will go completely offline again. Fortunately, many map apps allow for the downloading of maps for offline viewing before you get to your location. Google Maps supports such a feature on both Android and iOS devices while the Maps app on Windows 10 laptops and tablets also contains this functionality.   The iPhone and Android smartphone first-party cloud services, iCloud and Google Drive, are usually installed and enabled by default on their respective devices to save your data to their respective servers but there are also some third-party options that you may want to check out as a backup. Dropbox and Microsoft’s OneDrive two popular alternatives to the default smartphone cloud options but there are a number worth checking out. Most cloud services can work alongside each other to back up your data so if you reach your data limit on one, you can rest assured that one of the other services has picked up the slack. For example, a variety of music playlists may be available in the Fitbit Coach and other fitness smartphone apps when using them in the United States but you may find your song selection to be more limited when traveling to New Zealand. Once Upon a Time and Frasier may be on your Netflix list back home, but when traveling to Australia you may find that they disappear from the Netflix app completely. The changing of content within apps isn’t necessarily always a bad thing, though. While some of your favorite shows may become unavailable in Netflix when traveling to Japan for example, you’ll also gain access to a lot of great Japanese films and anime series that you wouldn’t be able to watch with your Netflix account back home.
