Real answer: it depends entirely on how much data you need and whether you're happy to commit to a year. Lebara wins decisively at some allowances; Ecotalk wins at others. Here's the actual comparison, using live pricing from both providers - not a generic "it depends" shrug, but the specific numbers so you can see exactly where each one pulls ahead.
Lebara runs on Vodafone's network. Ecotalk runs on EE's network - genuinely different infrastructure, not just different branding on the same masts. If you've ever had patchy signal on one network at home or at work, that distinction matters more than any price difference. Our network coverage comparison and the deeper EE vs O2 vs Vodafone vs Three breakdown are worth checking against your postcode before you decide on price alone.
Lebara's plans
Lebara offers both 30-day rolling and 12-month contracts, with the 12-month tier consistently 10% cheaper across every allowance:
- 5GB: £5.00 rolling / £4.50 on a 12-month plan
- 30GB: £10.00 rolling / £9.00 on 12 months
- 50GB: £15.00 rolling / £13.50 on 12 months
- 100GB (international): £20.00 rolling / £18.00 on 12 months
- Unlimited: £25.00 rolling / £22.50 on 12 months
- Unlimited (international): £30.00 rolling / £27.00 on 12 months
If you're weighing up whether a year's commitment is worth it purely for that 10% saving, our 12-month SIM only deals guide covers the real trade-offs - cancellation terms, what happens if your circumstances change, and whether the saving genuinely outweighs the flexibility you give up.
Ecotalk's plans
Ecotalk keeps things simpler - one tier structure, 30-day rolling only, no annual commitment option at all:
- No data (kids SIM): £4.00 - unlimited calls and texts, no data
- 3GB: £8.00
- 10GB: £12.00
- 30GB: £14.00
- 100GB: £18.00
- Unlimited: £22.00
Head to head, where the allowances overlap
At the price points where both providers compete directly:
- 30GB: Lebara £9.00 (12-month) vs Ecotalk £14.00 - Lebara wins by £5/month, a genuinely significant gap
- 100GB: Lebara £18.00 (12-month) vs Ecotalk £18.00 - dead even
- Unlimited: Lebara £22.50 (12-month) vs Ecotalk £22.00 - Ecotalk wins, but by only 50p
The honest takeaway: Lebara's wins depend entirely on committing to 12 months. If you want no-contract flexibility instead, compare Lebara's 30-day rolling prices - at 30GB, that's £10.00 rolling, which still beats Ecotalk's £14, just by a smaller margin. At Unlimited, Ecotalk's rolling £22 actually beats Lebara's rolling £25 outright - the one allowance where Ecotalk wins regardless of contract length.

Beyond price: what else genuinely differs
Ecotalk's environmental commitment is a real differentiator, not marketing gloss. The network directs 100% of profits to UK nature restoration and rewilding projects, with broadcaster Chris Packham serving as Chief Ecologist. If where your money goes matters as much as the monthly price, Ecotalk offers something Lebara simply doesn't - our full Ecotalk review goes into more depth on how that actually works in practice.
International calling tilts firmly toward Lebara. Every Lebara plan includes free calls to 42 countries as standard - genuinely useful if you regularly call family or contacts abroad, since that's not a feature Ecotalk's plans specifically offer.
Contract flexibility: Ecotalk is 30-day rolling only, full stop - you're never locked in, ever. Lebara gives you the choice: full flexibility on 30-day rolling, or a 10% discount for a year's commitment.
EU roaming: Both networks let you use your UK allowance in the EU, though the specifics (data caps, included countries) vary by plan - our guide to SIM Only deals with EU roaming breaks down exactly what's included where.
How Lebara and Ecotalk compare to the wider budget SIM market
Neither exists in isolation - both sit within a genuinely crowded budget SIM landscape. If you're still shopping around rather than set on these two specifically, our broader best SIM Only deals roundup and the more targeted best budget SIM Only deals guide cover the full field, not just this one comparison.
Two networks worth knowing about if this particular match-up doesn't land for you: 1pMobile, also on EE like Ecotalk, is worth comparing directly - we've covered Lebara vs 1pMobile and 1pMobile vs Ecotalk as their own dedicated comparisons. If you'd rather stay Vodafone-specific, VOXI vs Lebara is the other natural Vodafone-network match-up worth reading.
Rewild Mobile is another eco-focused option worth knowing about if Ecotalk's conservation angle appeals to you but you want different network coverage - it runs on Vodafone and Three rather than EE. Our Rewild Mobile review covers how its model compares to Ecotalk's.
If you're specifically weighing up budget networks on other host infrastructure, Giffgaff vs SMARTY covers the O2-and-Three side of the same budget-SIM question, and VOXI vs O2 and iD Mobile vs O2 are worth a look if coverage matters more to you than the absolute cheapest price. And Asda Mobile vs Honest Mobile is a similar-style head-to-head worth reading for context if you're choosing between two more established brands.
If either network's underlying reputation matters to you - customer service, network reliability, real user experiences - 1pMobile's full review and Mozillion's review are worth reading as further context, even though neither is a direct Lebara/Ecotalk substitute. Fonehouse's review covers a contract-based alternative if a SIM-only deal isn't quite the right shape for what you need.
Which should you choose?
Choose Lebara if: you're comfortable with a 12-month commitment and want the lowest possible price at 30GB or below, you regularly call abroad, or you specifically want the flexibility to choose between rolling and annual contracts.
Choose Ecotalk if: you want guaranteed no-contract flexibility with genuinely no compromise on price at the Unlimited tier, or you'd rather your monthly spend actively support UK conservation work.
If you're a student juggling budget and flexibility, our SIM Only deals for students guide covers both providers alongside options specifically suited to student contract lengths. If you're comparing for business use, our business SIM Only deals guide covers the different considerations that apply.
