Sort your data before your flight from Dublin
Buy your HelloRoam eSIM for Hong Kong at home, activate it over Wi-Fi, and enable data when you land in Hong Kong. You skip the airport telecom queues entirely and step off the plane already connected.
Keep your Irish number active
On a dual SIM phone, keep your Eir, Three IE, or Vodafone IE SIM for calls and texts while using HelloRoam for data in Hong Kong. Family and colleagues back in Ireland can still reach you on your regular Irish number.
Offline maps save data on city breaks
Download Google Maps or Maps.me for Hong Kong offline before you go. Offline navigation saves data and works even in indoor areas with weaker signal. Hong Kong cities are generally well covered but rural areas can be patchy.
Travel insurance and emergency numbers
Bring your EHIC or travel insurance details. Before you go, find out how to get emergency help at your destination and save the contacts in your phone. Your HelloRoam eSIM keeps emergency apps, insurance portals, and the Irish embassy contact details accessible throughout your Hong Kong trip.
Currency and card acceptance
Notify your Irish bank before travelling to Hong Kong. Card acceptance is generally good in Hong Kong but carry some local currency for smaller vendors and public transport. Currency conversion apps work well on a HelloRoam data connection.

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.
