"People buying 3G dongles should note that they have little chance of using them outside the M25."
My other half bought a 3 USB dongle... The map showed her area was high strength, and it should work inside the house without any problem.
She could barely use it by putting the laptop on the window ledge! It ended up taped onto the window on a USB extension lead! Hardly the image they portray in the blurb!
I gave her a few choice quotes from the sale of goods act "unfit for purpose" being the main one, and she went back to the shop.
Oh, and what deserted part of the country does she live in... Lambeth!
