As a traveler, I truly have no clue how anyone travels without using T-mobile. I have found my experience with them so seamless, time and time again. Here’s why You get unlimited everything in Canada and Mexico, it’s basically like you’re in America. Unlimited Text and Data almost everywhere else, and keep in mind data means iMessage, WhatsApps, all social media, messengers and chats are included! The only thing you can’t do for free is make a regular phone call. But you can turn on your wifi calling and make regular calls when on wifi. You can even do this on airplane mode to confirm you will not be charged. Another perk is 1 hour free gogo inflight (wifi) on Alaska, American, Delta and United. Also free AAA for a year!
