Lebara has slid in with the cheapest Boxing Day deal, offering a cheap and flexible deal that’s perfect for users who don’t spend a lot of time using their phone and so don’t want to pour a lot of cash into it.

5. Vodafone SIM-only | 100GB data, unlimited calls and texts | £54 cashback | £16/mth

This Vodafone deal works out at only £11.50 per month after you’ve factored in the cashback, which is a great price for 100GB of data. It’s a 12-month contract, so you’re locked in for a year, but when the deal is this good it’s hard to complain. At this price, it’s as good as it gets for Vodafone.
