30GB for £10/pm and 50GB for £15/pm - Smarty's SIM only deals are a Boxing Day delight

Christmas-themed socks; cinnamon-scented candle; new smartphone. In that order.

If your list of favourite gifts looks something like ours, then you might be spending your Boxing Day looking for the perfect SIM only deal (and/or trying to dissipate that pungent cinnamon whiff from your home).

If Three's sensational £18/pm for unlimited data SIM is just a bit more than you want to pay (or the thought of a 12-month contract is looking less palatable than yesterday's leftover sprouts) then Smarty might be a better fit.

Costing just £10 a month for 30GB for data or £15 a month for 50GB, there are no other plans offering anywhere near this much data for these prices.

Tempted? We can understand why. Find out more about these superb SIM only deals below.
