Before you travel – United Kingdom

  • How much data

    A week of maps, translation and social media usually fits in 3–5 GB. Sharing data with a laptop or streaming video, take 10 GB or more.

  • Networks and speed

    Plans use 3, O2, or Vodafone, depending on the plan. Every plan supports 5G. Your phone picks the network itself; there is nothing to set up.

  • When validity starts

    Each plan says whether validity runs from installation or from first connection. Install the eSIM accordingly.

  • Calls and texts

    Plans are data only. Call over WhatsApp, FaceTime or Messenger. Texts from your bank still reach your home SIM if you leave it on and switch off only its data.
