The United States has extensive 5G and 4G LTE coverage across its cities and major tourist regions. T-Mobile and Verizon cover New York, Los Angeles, Miami, Chicago, Las Vegas, San Francisco, and the principal national parks. Rural areas in Nevada, Utah, and Montana can have limited signal between towns. A HelloRoam eSIM means you step off your flight at JFK, Heathrow to LAX, or any major American gateway already connected to a US network. 175+ keeps you online across the whole country.
Set up your eSIM before you fly across the Atlantic
Install your HelloRoam eSIM at home before your long-haul flight to the States. Switch on your US data line as you land and you will have connectivity in the arrivals hall. No need to search for an AT&T or T-Mobile store or join the queue at airport kiosks.
US vocabulary for British travellers
Americans use different terms you will need for maps and directions. A pavement is a sidewalk, a boot is a trunk, a queue is a line, and a mobile is a cell phone. Your HelloRoam eSIM's Google Maps will use American English, so be prepared for 'sidewalk' directions even if your phone is set to British English.
National parks and remote driving routes
America's famous road trips , Route 66, the Pacific Coast Highway, or drives through Utah's Mighty Five , pass through areas with very limited signal. Download offline maps of your route and national park trail maps before leaving your city hotel. The Grand Canyon South Rim has reasonable coverage but the canyon floor and North Rim are largely off-grid.
Temperature in Fahrenheit across the US
The US uses Fahrenheit rather than Celsius. A rough conversion: 32°F is freezing (0°C), 68°F is comfortable (20°C), 86°F is hot (30°C), 104°F is very hot (40°C). Summer in Phoenix, Las Vegas, and Miami can exceed 100°F (38°C). Keep your HelloRoam data active so you can check weather apps and local alerts.
Keep your UK number active for bank security
Many British banks send SMS two-factor authentication codes to your UK number. Keep your UK SIM active in your dual SIM phone whilst using HelloRoam for US data. This ensures you can access online banking without issues throughout your American holiday.
The US has three main mobile operators: T-Mobile, Verizon, and AT&T. HelloRoam connects on T-Mobile and Verizon, which together provide the widest 5G footprint in the country. T-Mobile has the largest 5G coverage by geography. Verizon has dense urban 5G. Both networks are strong in cities and major tourist areas. Rural coverage is better on T-Mobile's nationwide 5G network.

The USA is a vast country and timing depends on which region you are visiting. New York is delightful in spring (April to June) and autumn (September to November) with temperatures between 15°C and 25°C. Florida is best from November to April to avoid hurricane season and summer humidity. California is pleasant year-round with Los Angeles around 20°C to 28°C throughout. Las Vegas and the Southwest are best in spring and autumn. The summer school holidays (July and August) see peak prices for flights and hotels across the country.

An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone, tablet, or smartwatch. It lets you activate mobile plans electronically without inserting a physical SIM card. Unlike traditional SIM cards, eSIMs are reprogrammable. You can switch networks or plans instantly through software on compatible devices like iPhone 14, Samsung Galaxy S23, or Google Pixel 8.
To check if your mobile supports eSIM, go to Settings, then Mobile Data (iPhone) or Settings, then Network & Internet (Android) and look for 'Add eSIM' or 'SIM card manager' options. Most flagship mobiles released after 2018 support eSIM, including iPhone XS and newer, Samsung Galaxy S20+, Google Pixel 3+, and many modern Android devices. You can also dial *#06# to see if an EID (eSIM identifier) appears.
To install your Hello Roam eSIM, follow these 3 steps: (1) Purchase your plan from the Hello Roam dashboard and receive your QR code via email within minutes, (2) Open Settings, then Mobile Data, then Add eSIM on your device (iPhone) or Settings, then Network & Internet, then Mobile Network (Android), (3) Scan the QR code or enter the manual activation code to complete installation in 2 to 5 minutes. Make sure you are connected to Wi-Fi during setup.
eSIM activation is usually instant but can take 2 to 10 minutes depending on network conditions and signal strength. If activation takes longer than 10 minutes, try these steps: restart your device, toggle aeroplane mode on and off for 30 seconds, check that the eSIM profile is set as your active data line, or confirm you are in an area with good network coverage.
Yes, most modern smartphones support dual SIM, letting you use one physical SIM card and one eSIM at the same time. This is ideal for travellers who want to keep their home number active for calls and texts whilst using a Hello Roam eSIM for affordable local data. You can choose which SIM handles calls, messages, and data in your device's mobile data settings under 'Primary' or 'Default' line options.
5G support on Hello Roam eSIMs depends on the local network included in your plan and your device's 5G compatibility. Many Hello Roam plans include 5G access where partner networks offer 5G coverage in major cities and urban areas. Your device must support 5G bands used in the destination country (check device specs), and you will automatically connect to the fastest available network (5G, 4G LTE, or 3G) based on coverage.
You can check your Hello Roam eSIM data usage in two ways: (1) Hello Roam Dashboard: log into your account at helloroam.com to view real-time data consumption, remaining balance, and plan expiry date. (2) Device Settings: on iPhone, go to Settings, then Mobile Data, then your eSIM line. On Android, go to Settings, then Network & Internet, then Mobile Network, then Data Usage. Dashboard data updates every 15 to 30 minutes, whilst device-level usage is tracked locally and may differ slightly from network reporting.
Refund eligibility varies by plan. Generally, refunds are available if the eSIM has not been installed or activated. Contact support with your order ID for refund requests. Once approved, refunds typically process within 5 to 14 working days depending on payment provider and bank processing times.
QR codes are typically single-use for security. If you need to reinstall, use the reinstall option in your account or contact support for a new activation method.
Contact Hello Roam support through multiple channels: (1) Live chat available 24/7 on our website at helloroam.com/contact, (2) Email us at help@helloroam.com with your order ID for faster help (average response time under 2 hours), (3) Use the in-app Help section for instant answers to common questions, or (4) Check our FAQ database. For urgent issues whilst travelling, live chat is the fastest option.
