Prepaid mobile broadband without the faff of monthly contracts, this Three preloaded unlimited 5G data SIM sits in the same space as PAYG data bundles and rolling 30 day unlimited plans, but with a long validity window. It’s set up for heavy data use on the Three network, with dual network support listed for Three and Vodafone, which can be useful if coverage varies where you live, work, or travel.

Who is this for?

It suits anyone who wants a “set it and forget it” data SIM for a tablet, 4G or 5G router, or a spare phone used for hotspotting. The key detail is the end date, valid until July 2028, so it’s aimed at people who want long term certainty rather than renewing every month. As with any unlimited SIM, performance depends on local signal and network management at busy times.

  • Validity: usable until July 2028, helpful for long term use or backup connectivity
  • Networks: listed as dual network (Three and Vodafone), relevant if one network is patchy in your area
