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 French Guiana. Family and colleagues back in Ireland can still reach you on your regular Irish number.
Offline maps save data on city breaks

Currency and card acceptance
Notify your Irish bank before travelling to French Guiana. Card acceptance is generally good in Cayenne 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.
