Lebara vs SMARTY (2026)

SMARTY and Lebara are both strong no-contract, SIM-only options, so the right pick really comes down to how you use your phone. If you mainly want simple, low-cost UK data with a clean app and no frills, SMARTY is excellent value. If you regularly call abroad or want wider included international calling alongside solid UK coverage, Lebara is the more natural fit and you can start at 50% off for your first 3 months via a referral link.

The verdict

SMARTY and Lebara are both strong no-contract, SIM-only options, so the right pick really comes down to how you use your phone. If you mainly want simple, low-cost UK data with a clean app and no frills, SMARTY is excellent value. If you regularly call abroad or want wider included international calling alongside solid UK coverage, Lebara is the more natural fit and you can start at 50% off for your first 3 months via a referral link.

SMARTY is owned by Three (part of the wider CK Hutchison group) and runs entirely on Three's UK network, positioning itself as a stripped-back, app-first, SIM-only brand for people who want cheap data without extras. That focus is its niche, and also why it's a less natural choice for heavy international callers than Lebara, which is built around the diaspora calling market on the Vodafone network.

Where Lebara tends to win

• International calling is Lebara's home turf: SIM-only plans include calls to 50+ countries at no extra cost, with allowances that scale up to unlimited international minutes on the top tiers, whereas SMARTY treats most international calls as a paid add-on or per-minute charge.
• Lebara runs on the Vodafone network with around 98% UK population coverage, which in many areas gives broader reach than SMARTY's Three-based network, particularly in rural spots and on indoor signal.
• Entry pricing is genuinely cheap (plans from around £5/month), and a referral link gets new customers 50% off their chosen SIM-only plan for the first 3 months, so the real starting cost can undercut a like-for-like SMARTY plan.
• Both are no-contract, but Lebara pairs that flexibility with a diaspora-focused feature set (International Call Passes, calls bundled in by default) that SMARTY simply doesn't aim to match.
• No credit check to join Lebara, which makes it easy for students, new arrivals and anyone without UK credit history to get started straight away.

Where SMARTY has a case

• SMARTY's pricing for pure UK data is very keen and refreshingly simple, with straightforward unlimited and tiered data plans and a tidy, well-rated app for managing everything yourself.
• Running on the Three network, SMARTY tends to perform strongly for fast 5G data and generous data allowances in well-covered urban areas, and Three's network is often praised for raw data speeds.
• SMARTY offers neat touches like a discount when you don't use all your data on certain plans and group/family savings, which appeal to data-led users who don't call abroad.

How to switch to Lebara

Switching to Lebara is quick and there's no contract tying you down. To get 50% off your first 3 months, click through a Lebara referral link and you'll go straight to the SIM-only plans, where the discount applies automatically at checkout once you order as a new customer and activate your SIM. There's no code to type in, just pick a 30-day rolling or 12-month plan and follow the link. To keep your existing number, text PAC to 65075 from your current SIM to get your PAC code, then give that code to Lebara during sign-up and your number transfers across. Being transparent: you get the 50% off as the new customer, and if you join via someone's link and stay active, the person who shared it may receive a small cash reward, at no extra cost to you.
