Why Free Trial eSIM is better than Roaming

1. Local Breakout in London

Traditional roaming routes your data back to your home country, creating lag. Our eSIM connects you locally in London, reducing latency for fast Uber rides and Maps.

2. Powered by Vodafone / O2

We don't use cheap budget networks. In United Kingdom, your phone will connect to Vodafone / O2 antennas, ensuring coverage even at remote spots like Big Ben.

📸 Share Your Moments from Big Ben

With our high-speed data, you can upload 4K videos from Big Ben or livestream your walk through London without buffering.
