3 internet

partimer

we got 3 internet , the usb dongle that plugs in to the laptop,

but ok for a week , never used it since as the reception was that poor there wasnt hardly any signal

can i cancel my contract with them, as it isnt going to get used again,

I've never cancelled from "3" but I'm in a good signal area!!.
but in general:
Depends on how long you've had the contract.

0-14 day's then you could probably cancel it quite easy.

14-31 days might be a bit of a hassle. (and pay the months rental)

32+ days, probably not! unless you pay the rest of the contract.
