Data roaming for American travelers is not remotely affordable. While traveling, most Americans turn off their data roaming because it is pricey and don't get an international SIM card because it is inconvenient. Yes, an un-carrier like T-Mobile provides sponsored "roaming" but it's a slow, sub-2G service at best; not sure you want that kind of "back-to-the-future" service given all your everyday mobile apps.
To take a sample trip, if you're traveling from the US to Europe for 10 days and you want LTE data roaming, you may end up paying U$80-100. But that's too much for one trip. And travel using free WiFi-only is not secure and not as fun. From ride sharing to maps, ratings and messaging apps, travelers can enjoy better experiences when always-connected through cellular data. Thanks to eSIM-capable smartphones*, now travelers can get affordable cellular data (as low as U$10-30 per trip) in few clicks through QR codes!Here is a video showing how it works with CELITECH service.*eSIM capable smartphones in the US currently include iPhone 11/SE/XR/XS,Google Pixel 4/3,Samsung Galaxy S20&Fold,Huawei P40andMotorola Razr. eSIM is also available in laptops and pads like iPad Pro and Microsoft Surface among others.
