Andy Aitken and Josh Mihill enter the Den with Honest Mobile, the UK’s first certified B Corporation mobile network, and one built on sustainability and transparency.

Founded in 2019, Honest Mobile gives 1% of its revenue to environmental causes and is officially carbon negative.

Its key feature, the Smart SIM, is a data-only eSIM that connects to whichever of the UK’s four major networks – EE, O2, Three or Vodafone – offers the strongest signal when your main SIM drops out.

Starting from £3.75 per month, the plan offers unlimited data on 500+ supported apps and free roaming in more than 180 countries.

Honest also rewards loyal users with monthly bill discounts, encouraging customers to stay for the long term.
