Best Time to Visit Réunion
Réunion's dry season from May to November is the best time for hiking and beach visits. The wet season from December to April brings cyclone risk and heavy rain in the east and highlands. The western coast around Saint-Gilles-les-Bains stays drier year-round. Volcano hikes to Piton de la Fournaise are best in the dry season. Always download offline maps before entering the cirques.

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.
