Quick tip for digital nomads heading to the UK:
If you want cheap mobile data, get a 3 (Three) Pay As You Go Mobile Broadband SIM. For a measly 2£ at the nearest WH Smith (there's a lot of them on airports), you get a starting allowance of 1GB data. As soon as that runs out, just buy another SIM and repeat!
I did this once a week during my three week stay in the UK and except for the London subway, the network ran flawlessly!
The SIM-card works as well on your smart phone as on a tablet or MiFi device. Also, since it's meant for mobile broadband, tethering is allowed unlike with many other pay as you go SIMs.
