Traveling internationally is one of the greatest experiences you can ever have… except when it comes to staying connected with your phone. We’re all for disconnecting as much as possible, but sometimes it’s necessary to check in with loved ones and meet up with friends abroad. Which brings us to the giant pain in the ass that is international data networks. You need an unlocked phone and, most of the time, a different SIM for each of the countries you’re going to be spending any amount of time in. If you’re one of those people that would prefer to message over talk on the phone, check out WhatSim. WhatSim connects to over 400 mobile operators in around 150 countries to give you access to your messaging apps without having to search for free WiFi or pay astronomical international data rates. Once you load up some data credits, it’s as simple as putting WhatSim in any unlocked phone.
