Worked great

I used two plans. One for a week in the Jungfrau in Switzerland where it connected flawlessly with Swisscom and then a different plan for the UK which also worked well. Easy to install and reliable service. I had previously tried using Nomad as that service is highly rated but Nomad’s installation process, customer service, and connectivity were atrocious. Highly recommend ByteSIM.

Good Value & Performance

The reason why bytesim is cheap is because they are using international roaming agreements and centralised internet gateways located outside the country your visiting. This means the only downside is higher latency. Visited Costa Rica, I can see my internet traffic to google goes to London and breaks out there. latency is 300 -400 ms
