eSIM Travel Tips for USA
Singapore Airlines flies direct to the US: sort your eSIM before you board
Singapore Airlines has direct flights from Changi to Los Angeles (18+ hours) and to New York (via Los Angeles). Set up your HelloRoam eSIM the night before your Changi departure. Enable data when you land at LAX or JFK and Uber, Google Maps, and Yelp work straight away from the arrivals terminal.
Uber and Lyft are essential for US city transport
Uber and Lyft are the main ride-hailing apps across the United States. From LAX to your hotel in Santa Monica, or from JFK into Manhattan, these apps need live data. Your HelloRoam eSIM keeps ride-hailing running from the moment you clear US Customs and Border Protection.
