Mobile connectivity guide for the United States

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.
Hawaii is a popular SG family destination
Hawaii (particularly Honolulu and Maui) is a very popular destination for Singapore families during school holidays. Good 5G and 4G coverage throughout Waikiki, Honolulu city, and Maui resort areas. Your HelloRoam eSIM works from arrival at Honolulu Daniel K. Inouye International Airport.
Las Vegas and the Grand Canyon: strong city, spotty canyon
Las Vegas has excellent 5G on the Strip and throughout the city. The Grand Canyon National Park has very limited signal in the canyon interior and on the Rim Trail. Download offline maps of the South Rim and Grand Canyon trails before leaving your Las Vegas hotel.
New York City: strong 5G across all five boroughs
New York City has excellent 5G throughout Manhattan, Brooklyn, and all five boroughs. Citymapper and Google Maps navigate the subway system effectively. Your HelloRoam eSIM keeps NYC transport apps, Yelp restaurant reviews, and Broadway ticket apps running throughout your New York holiday.
Mobile networks in the US: what Singapore visitors need to know
HelloRoam connects on T-Mobile and Verizon in the United States. Both are top national operators with 5G in all major cities and strong 4G across the country including national parks and rural areas. Remote wilderness areas like parts of Yellowstone and the Grand Canyon interior will have limited signal.

HelloRoam eSIM vs Singtel, StarHub, or M1 US roaming
Your data options for a United States trip from Singapore.
| Category | HelloRoam eSIM Recommended | US SIM or airport SIM | Singtel, StarHub, or M1 US roaming |
|---|---|---|---|
| Typical cost | From SGD 3.85 total | SGD 19.27–SGD 77.08 total | SGD 12.85–SGD 25.69/day |
| Details | Plans from S$3.69. Buy before your SIA long-haul flight from Changi, activate at home, and land in Los Angeles or New York already on local T-Mobile or Verizon 5G. No SIM setup after 18 hours of flying. | US prepaid SIMs are available but setting one up after a long-haul flight from Singapore is inconvenient. A HelloRoam eSIM activated at home before departure is the better option. | Singapore carrier US roaming packages can cost $10 to $18 per day. Three weeks exploring New York, LA, and Hawaii on SG roaming adds up significantly compared to a HelloRoam eSIM. |

Best time to visit the United States from Singapore
The US is a year-round destination with very different weather by region. Hawaii is best from April to October for beach weather. New York and the East Coast are best in spring (April to June) and fall (September to October). Las Vegas and the Southwest are best in spring and autumn to avoid extreme summer heat.

On a trip to Europe, my hotel Wi-Fi was so slow and outside Wi-Fi was unreliable. I couldn’t take it anymore so I got helloroam for a few days. It was tricky to set up correctly because of the primary settings (with my original number). But I reached out to their customer service via WhatsApp. Super responsive and helpful, with specific and clear steps to troubleshoot. Appreciate having 4G roaming instead of being stuck with in and out Wi-Fi during my trip!!

Very good experience! The eSIM was easy to set up and worked great in London. It was much cheaper than it would have been to use my own operator there.

- The PNN is the network name field inside your eSIM profile, defined in the 3GPP standard TS 31.102 (EF_PNN). Your handphone can read this field to display the name of the network you are connected to.
- Access Point Name (APN)
- Your HelloRoam eSIM sets its Access Point Name automatically during installation. Your handphone picks up the strongest local network without any manual settings to fiddle with.
Prices shown are HelloRoam's retail rates across 185+ countries. Plan picks are based on real traveller feedback and network performance data, not guesswork. You can get a refund on unactivated eSIMs within 180 days.
