Tech retailer Expansys has cut a deal with 4G network EE to offer a super-cheap 4G data SIM, loaded with a 5GB data allowance -- and your first month free. Entering the code FREE4G when buying a £1.99 EE SIM from the shop gets you access to the 4G dream. Usual cost £15.99. Terms and conditions apply. Seems legit. Give it a go if you live in an LTE hotspot. [Expansys via Recombu]
