The advertised price is the half-price price. Across the whole contract, Lyca's plans cost up to 92% more than the advert. But 6 of the 20 we could compare are still the cheapest on our site for that much data once the discounted months are counted.

The small print, in large printWhat these numbers don't tell you
- Real cost / month assumes you join on 2 October 2026 and stay for the whole contract. Rolling plans are costed over 24 months at today's price; a rolling plan's price is not fixed unless the network says so, but you can leave any month.
- Stated price rises are included where the network publishes them in pounds and pence. Where a network says nothing about rises, we assume none, which may flatter it.
- Not included yet: early exit fees on contracts, speed caps, fair-use limits on "unlimited" data, tethering limits and charges for going over your allowance. We have not collected these, so we make no claims about them.
- £/GB uses the ongoing allowance, not temporary bonus data.
- Price over time bars: green months are an intro price, grey the normal price, red months after a stated rise. Bar height is that month's price.
- Coverage depends on where you live. Check your postcode on Ofcom's coverage checker.
- "Still the cheapest" compares the real monthly cost with every plan from the other six networks that has at least as much data. It does not weigh coverage, contract length or extras.
