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.
