Can I get money back for unused data?
Yes, Data Discount Plans refund £1 for every GB you don't use. With customers typically using only 34% of their allowance, this often means significant monthly refunds on your bill.

How do SMARTY referral rewards work?
Refer friends and both earn £10-£40 depending on their plan choice. Rewards are issued after their third month via PayPal or gift cards for Amazon, John Lewis, or Uber.
Do SMARTY student plans require verification?
No verification needed. Student plans start from £6 with the same features as standard plans including 5G, unlimited calls and texts, and EU roaming up to 12GB.
What's included in the Winter Sale offer?
24GB data for £7 — triple the usual 8GB allowance at the same price. This limited-time offer provides exceptional value for customers needing more data without unlimited costs.
Can I use SMARTY abroad?
Yes, EU roaming is included with up to 12GB of your data allowance usable across European Union countries at no extra charge on all plans.
Are there any long-term contracts with SMARTY?

More Ways to Save Money at SMARTY
SMARTY has built its whole service around one idea: putting money back in your pocket. Beyond their headline Winter Sale offering triple data, there are multiple ways to reduce your monthly mobile spend — from group discounts that reward loyalty to innovative data refunds that ensure you never pay for what you don't use. Here's how to unlock every available saving.
Apply a SMARTY Discount Code, Step by Step
When SMARTY releases promotional offers, applying them at checkout is refreshingly straightforward. Their streamlined process ensures you'll never miss out on available savings.
- Browse available deals on comparison sites or SMARTY's homepage to find current offers
- Select your preferred plan from SMARTY's range, ensuring it matches any offer requirements
- Proceed to checkout and look for the "discount code or gift card" box during payment
- Paste your code and verify the discount appears before completing your order
- Complete payment — your discounted rate will apply from activation
If your code doesn't work, double-check it's still valid and applicable to your chosen plan. Some offers exclude Social Tariff or Group Plan combinations, so review the terms before checkout.
Save Up to £33 Monthly With Group Plans
SMARTY's Group Plans turn family mobile bills into serious savings opportunities. By bundling 2-8 SIMs together, you'll slash costs whilst maintaining individual plan flexibility.
Everyone Unlimited Group Plan
Perfect for data-heavy households, this option costs £18 for the group owner plus £15 for each additional member. With up to 8 SIMs allowed, a full group saves £33 monthly compared to individual unlimited plans. Everyone gets truly unlimited data, so there's no rationing or overage worries.
Mix & Match Group Plan
Ideal for families with varied usage, this delivers a 10% discount per member on any plan they choose. Light users can pick smaller data allowances whilst heavy streamers opt for unlimited — everyone saves regardless of their individual needs. The group owner manages all payments and usage from one dashboard, simplifying household mobile management.
Get Money Back for Unused Data
SMARTY's Data Discount Plans flip traditional mobile pricing on its head. Instead of losing unused data, you get £1 back for every GB you don't use. Given that average customers only use 34% of their monthly allowance, this could mean substantial monthly refunds.
Plans start with a £5 base covering unlimited calls, texts, and network access. Data costs £1 per GB on top, but unused portions are refunded automatically. A 3GB plan costs £8, but if you only use 1GB, you'll get £2 back — making your effective cost just £6.
Earn Up to £40 Per Friend Through Referrals
SMARTY's referral programme offers some of the most generous rewards in mobile. There's no limit to how many friends you can refer, making this a genuine money-maker for social customers.
Reward Tiers
- £40 each when your friend chooses a plan costing £15+ monthly
- £20 each for plans between £10-£14.99 monthly
- £10 each for plans under £9.99 monthly
Rewards are issued as PayPal payments or gift cards for Amazon, John Lewis, or Uber after your friend's first renewal (their third month). You'll receive your unique referral link through your dashboard once your SIM activates, and Buyapowa handles all reward distribution.
Social Tariff: Unlimited Data for £12
Customers receiving eligible benefits can access unlimited data for just £12 monthly — £6 cheaper than standard unlimited plans. This includes 5G access, unlimited UK calls and texts, plus EU roaming up to 12GB.
Eligibility covers income-based employment support, job seekers allowance, income support, pension credit, or universal credit. SMARTY partners with DWP for validation, making applications straightforward without affecting your credit score. Validation occurs annually, and if circumstances change, you'll migrate to a standard plan at no higher cost than the Social Tariff.
Free SIM Cards and London Underground WiFi
Get Your SIM Card for Free
SMARTY eliminates common mobile network charges that add up over time. SIM cards are completely free when ordered online, though physical stores may charge around £1. This extends to replacement SIMs if you switch devices or need a different size.
Connect to Free WiFi on the London Underground
As a bonus, SMARTY customers get free WiFi across London's transport network. Connect to 'Three_WiFi' at over 250 stations, including all Tube stations, most London Overground stops, and Elizabeth line stations under central London. It's a small perk that saves data allowance during commutes.
Student Plans From £6 With Full Benefits
SMARTY's student offerings aren't watered-down versions — they're the same feature-rich plans available to everyone, starting from £6 monthly. Students get 5G access, unlimited calls and texts, EU roaming, and the same 1-month flexibility as standard customers.
Plans range from 5GB at £6 up to unlimited data at £18, with no student verification required. The minimum age is 16 for independent accounts, though younger students can join with parental consent. Unlike many student deals, there's no end date when you graduate — simply continue or change plans as needed.
Winter Sale: Triple Data at No Extra Cost
SMARTY's current Winter Sale demonstrates their approach to seasonal promotions — genuine value rather than marketing gimmicks. The standout offer provides 24GB for £7, tripling the usual 8GB allowance without increasing the price.
This limited-time promotion targets customers who need more data but don't want to jump to unlimited plans. It's particularly valuable for students, remote workers, or anyone whose data needs have increased. The offer applies to new customers and existing ones looking to upgrade their monthly allowance.
Customer Support at SMARTY
SMARTY operates primarily through digital channels, keeping support costs low whilst maintaining responsive service. Most account management happens through their app or website dashboard.
- Live chat available through the website for immediate queries
- Email support for detailed account issues
- Social media responses on Twitter and Facebook
- Help centre with comprehensive FAQs and setup guides
Their self-service tools handle most common tasks like plan changes, usage monitoring, and payment management, typically resolving issues faster than traditional phone support.
