Past discounts at Smarty

You can find a Smarty discount throughout the year, as they consistently provide offers rather than focusing on specific seasonal sales. A popular way to save is through their refer-a-friend program, which often provides a gift card for both you and your friend. Another regular promotion is the group plan discount, which helps reduce costs for multiple SIMs. While you might not always find a traditional discount code, these ongoing deals ensure there are always ways to lower your mobile bill. Looking at past offers, the average discount has been around £26, with the maximum savings reaching a £40 gift card. Keep an eye on their website for the latest opportunities to get a discount on your Smarty plan, as a new discount code could appear at any time.

News

New plan options now available at Smarty

Smarty has updated its plan range with several rolling monthly options, giving you more choice if you want to keep your mobile costs simple. The current lineup includes plans from 5GB through to Unlimited, plus a 32GB option at £8 and 140GB at £12. That makes it easier to pick a plan that matches how much data you actually use. If you are comparing mobile deals, it is worth checking the latest offers on the Smarty site.

Refer a friend and unlock extra rewards

SMARTY’s refer-a-friend offer is still a useful way to get more from your mobile plan. The brand says both you and a friend can earn gift card rewards when they join and stay on for the required months, with amounts linked to the plan chosen. That gives you a practical reason to share your link if someone you know is looking for a simpler mobile option. Check the latest promotions before signing up.

You can now text shortcodes

Smarty now supports SMS shortcodes, useful for one‑time passcodes, parking, charity donations and TV votes. Free shortcodes work straight away; chargeable ones require out‑of‑plan credit and are covered by spend limits. If a message fails, try the shortcode checker and confirm any content‑filter settings. This update makes everyday services simpler when you’re out and about. If you’re reviewing plans, take a moment to look at current promotions.
