Frequently asked questions
  • How can I get a discount from SMARTY?

    Promotional SIM-only plans are listed in the Special Offer section on SMARTY's website, with offers such as doubled data allowances or reduced monthly rates. No separate promo code is required at checkout: choose the advertised plan online to claim the deal.

  • Does SMARTY deliver SIM cards for free?

    Yes, physical SIM cards ordered online from SMARTY come with 100% free delivery to UK addresses. You can also choose an eSIM for instant digital delivery with no postage needed.

  • Which payment methods does SMARTY accept?

    SMARTY operates on a 1-month upfront payment model and accepts Visa, Mastercard, PayPal, Apple Pay, and Google Pay. Customers can also pay cash in-store at PayPoint retailers; Direct Debit and BACS payments are not accepted.

  • How does SMARTY's refer-a-friend reward work?

    Active customers can share a unique referral link or order up to two free physical SIMs monthly. When a friend signs up and reaches their renewal, both the referrer and referee receive a £5, £10, or £20 reward based on the chosen plan, redeemable as PayPal cash credit or a gift card for Amazon.co.uk, John Lewis & Partners, or Uber.

  • Does SMARTY offer a money-back guarantee?

    New customers can cancel within 14 days of ordering under SMARTY's 14-Day Money Back Guarantee. If the SIM is unactivated, you can cancel and get a full refund via the dashboard; if it was used, refunds are calculated pro-rata based on usage and returned to the original payment method within 5–7 working days.
