eSIM Travel Tips for USA
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.
Mobile networks in the USA: what Irish visitors need to know
HelloRoam connects on T-Mobile, Verizon, and AT&T in the US. All three operators offer 5G coverage in major cities with strong 4G filling suburban and rural areas. Your eSIM picks the strongest available signal automatically as you move between cities and states.

Cat
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!!
Rated 5 out of 5 by this reviewer

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.
