Why Tesco Mobile doesn't offer a free SIM card
Unlike networks like giffgaff or Smarty, Tesco Mobile doesn't post out standalone free SIM cards. Their business model is built around paid SIM-only contracts — you get a free SIM included whenever you sign up to a plan, but there's no way to order just a SIM with no commitment.
If you specifically want a totally-free SIM with no plan, look at our free SIM comparison. Otherwise, Tesco Mobile's SIM-only deals start from £8/month and the SIM itself is free with any plan.
