Went instore yesterday and got this deal:
Free ZTE dongle
1 month rolling contract
Just £3 total
Supposed to be for existing customers which i am but no one asked me for any details they just did it. Now here is the good bit , you can cancel the next day and still get the full month . I know as i have just done this for the 2 dongles i got. However if you want to keep it they are open to negotiating and looking to get a better deal than there is and they offered me some options.
You call call 500 from your three phone to talk to them.
So i think this is a great deal for just £3 for one month 5gig , whether for yourself or a visitor BARGAIN.
