The US has brilliant 5G and 4G coverage across its major cities and interstate corridors. T-Mobile and Verizon cover New York, Boston, Chicago, Los Angeles, San Francisco, and the Wild Atlantic Way equivalents on the US coasts. Rural stretches of the Midwest and mountain states can be patchier, but the tourist trails are well served. A HelloRoam eSIM connects you automatically when you step off the plane at JFK, ORD, or LAX. No SIM hunting needed after a seven-hour flight. 175+.
Activate your eSIM before you board at Dublin
Install your HelloRoam eSIM on your phone at home the evening before you fly. Once you land in the US, switch on mobile data and you are connected immediately. No need to queue at a T-Mobile store or look for an airport SIM kiosk after a long transatlantic flight.
Download offline maps for road trips
US road trips are a rite of passage for Irish travellers. Stretches of Route 66, the Pacific Coast Highway, or the Rockies can have limited signal. Download offline Google Maps or Maps.me tiles for your planned route before leaving your hotel or Airbnb.
Monitor your data on city breaks
New York and Los Angeles generate serious data usage between maps, Instagram, and video calls home. The HelloRoam app shows your real-time balance with alerts at 80% and 95% usage. Top up inside the app if you run low during a longer stay.
Keep your Irish number reachable
On a dual SIM phone, leave your Irish SIM running for calls and texts. Set HelloRoam as your US data line. Friends and family can still ring your usual Irish number while you are exploring Manhattan or Yosemite.
Use your eSIM across multiple US cities
Your HelloRoam eSIM works across the entire United States on the same plan. Fly into New York, take the Amtrak to Washington DC, then catch a flight to New Orleans or Las Vegas without buying a new plan at each stop.
HelloRoam's US network uses T-Mobile and Verizon, the two carriers with the widest combined coverage in America. T-Mobile leads for 5G coverage nationally. Verizon is strong in suburban and rural areas. Your eSIM picks the stronger signal automatically as you move between cities and states.
Here is what your connectivity options actually look like for a US trip from Ireland.
| Category | HelloRoam eSIMRecommended | US prepaid SIM | Eir, Three IE, or Vodafone IE US roaming |
|---|---|---|---|
| Typical cost | $3.00–$49.00 total | $15.00–$60.00 total | $10.00–$20.00/day |
| Details | Plans start at $3.00. Buy before you fly, scan the QR code at home, and land in America already connected. No contracts, no carrier shops, no bother. | Available at Walmart or T-Mobile stores but requires setup time and you need to be in-country first. Not helpful when you want data from the moment you clear customs. | International roaming in the US can be expensive with many Irish plans. Daily or weekly add-on costs can add up quickly over a two or three-week American holiday. |
Prices approximate as of April 2026. Actual savings vary.
The US is a year-round destination depending on where you go. New York in autumn has stunning fall colours. Florida is ideal from October to April. The Pacific Coast is gorgeous in summer. Irish travellers often combine cities with national parks, road trips, or family visits. Direct flights from Dublin and Shannon to Boston, New York, Chicago, and Los Angeles make planning easy.

An eSIM (embedded SIM) is a digital SIM card built directly into your smartphone, tablet, or smartwatch that allows you to activate cellular plans electronically without inserting a physical SIM card. Unlike traditional SIM cards, eSIMs are reprogrammable, enabling you to switch carriers or plans instantly through software on compatible devices like iPhone 14, Samsung Galaxy S23, or Google Pixel 8.
To check if your phone supports eSIM, go to Settings → Cellular (iPhone) or Settings → Network & Internet (Android) and look for 'Add eSIM' or 'SIM card manager' options. Most flagship phones 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 → Cellular → Add eSIM on your device (iPhone) or Settings → Network & Internet → Mobile Network (Android), (3) Scan the QR code or enter the manual activation code to complete installation in 2-5 minutes. Ensure you're connected to WiFi during setup.
eSIM activation is usually instantaneous but can take 2-10 minutes depending on carrier network conditions and signal strength. If activation takes longer than 10 minutes, try these troubleshooting steps: restart your device, toggle airplane mode on/off for 30 seconds, ensure the eSIM profile is set as your active data line, or check that you're in an area with adequate network coverage.
Yes, most modern smartphones support dual SIM functionality, allowing you to use one physical SIM card and one eSIM simultaneously. This is ideal for travelers who want to keep their home number active for calls and SMS while using a Hello Roam eSIM for affordable local data. You can choose which SIM handles calls, messages, and data in your device's cellular settings under 'Primary' or 'Default' line options.
5G support on Hello Roam eSIMs depends on the local carrier 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 specifications), and you'll automatically connect to the fastest available network (5G, 4G LTE, or 3G) based on coverage availability.
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 expiration date, (2) Device Settings - On iPhone, go to Settings → Cellular → [Your eSIM Line]. On Android, go to Settings → Network & Internet → Mobile Network → Data Usage. Note that dashboard data updates every 15-30 minutes, while device-level usage is tracked locally and may differ slightly from carrier 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 5–14 business 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 assistance (average response time under 2 hours), (3) Use the in-app Help section for instant answers to common questions, or (4) Check our comprehensive FAQ database. For urgent issues during travel, live chat provides the fastest resolution.
