For those who want to experience the boundless expanse of the USA with their smartphone should leave high roaming fees at home. Letting loved ones know on Whatsapp that you arrived safely, calling an Uber or Lyft from the airport, finding a nice hotel or restaurant on Google, or staying up-to-date on Facebook and Instagram are among the things we quickly do on our smartphones.

AT&T is the best known carrier in the US and is listed among the 11 largest corporations (Forbes Global 2000) worldwide. AT&T distinguishes itself through great coverage and an excellent call quality (AT&T HD Voice). The US carrier combines many services for calls (US flat rates, international airtime), as well as large data packages (up to 50 GB). AT&T's plans and services live up to our highest standards and are regarded as premium SIMs. You can take advantage of AT&T's support in their many stores while in the United States

Up to 4 devices can be supplied with internet via Tethering (WiFi Hotspot), allowing you, for example, to use your iPad for navigation. Even a quick trip to Canada or Mexico is not a problem: the plans M and L allow you to use your data or make calls while you spend time across the border.

Your first destination is Canada or Mexico? Not a problem, you can activate and use your SIM there first.
