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.

HelloRoam St. Martin eSIM Questions Answered
How long do eSIM St Martin plans take to activate?
St. Martin visitors activate eSIM for St Martin plans in under two minutes by scanning a QR code on any compatible phone. HelloRoam connects to Orange 5G network from $1.14 across Marigot's French waterfront, Grand Case, and Orient Bay beach.

Does a HelloRoam Saint Martin plan cover Orient Beach and the Marigot market?
