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.

Transparency Notice
- Service Provider Name (SPN)
- That's HelloRoam you see up in your phone's status bar, not a mystery reseller name. The SPN is a standard field baked into every eSIM profile, and most travel eSIM resellers do not bother provisioning their own.
- Public Network Name (PNN)
- The PNN is the network name field in your eSIM profile, set out in 3GPP TS 31.102 (EF_PNN). Your phone can read it to show the name of the network you're connected to.
- Access Point Name (APN)
- Your HelloRoam eSIM sets its own Access Point Name automatically when it installs, so your mobile locks onto the strongest local network without you touching a single setting.
What you see is our standard retail pricing across 185+ countries, nothing marked up for the page you landed on. Plans get recommended off real traveller feedback and actual network performance, not guesswork. You can get a refund on unactivated eSIMs within 180 days.
