A practical savings guide for shoppers using Honest Mobile UK offers.
Honest Mobile does not list a discount code at the moment. Its savings are built into the plans. The Smart SIM annual plan is £45 a year, or £3.75 a month, which the page shows as £75 less than the rolling monthly plan at £10 a month. The Classic SIM starts from £12.15 a month, and its loyalty discount lowers the bill every month you stay, up to 30% off.
You can share a referral link from the account section of the app. When your friend orders and activates a Classic or Smart SIM, you both get £5 credit, and former customers who rejoin count too. A referral applies only to the first SIM activated on an account.
Classic SIM gives unlimited UK calls and texts, 5G data on 4GB, 10GB or Unlimited plans, monthly or 12 month terms, and 5 days of free EU roaming on every trip. Smart SIM works alongside your main SIM on any network, connects to EE, O2, Three and Vodafone, and gives unlimited data on 500+ essential apps with free roaming in 180+ countries. Smart SIM comes with a 14 day money back promise, and the monthly plan can be cancelled at any time.
