Why eSIM is more convenient than a local SIM in the USA
American operators often sell service on subscription tied to a local card and address, while prepaid SIMs need to be found in stores. eSIM can be purchased online in minutes and works immediately after arrival — from the airport to car sharing and restaurant bookings.
How much data do you need for a trip across America
If you move a lot by car with a navigator, listen to music, and use taxi apps, plan for 5-10 GB for a week. For a road trip or remote work, unlimited packages are more convenient.
Coverage
eSIM connects to major national networks — their list is provided with each package. In cities and along highways, 4G/5G works; in national parks, deserts, and mountains, there may be no service from any operator, so it's better to download offline maps in advance.
