    The most flexible data plans. Highly recommend using the calculator on their site. It allows complete freedom over your holiday internet data budget. Never overpaying for data again! ✨ Highly satisfied with service.

    Great internet speed abroad. Streaming videos and using maps worked perfectly. Speed was surprisingly good in most places.

    Thought it might be tricky, but it was actually super easy. Got online in minutes and didn’t think about it again.

  • Matthew Scott

    Only needed internet for a few days and didn’t want any long-term plans. What I liked is that you can just choose exactly how many days and how much data you need with their calculator. No fixed packages, no overpaying for extra GB you won’t use. And if you run out, you can always top up. Super flexible.
