On the 18th of July, if I remember rightly, I paid off my phone and switched to sim as it was cheaper for me at the time. While I was there I had asked if all the insure would come off it too as I didn't want it any more. I was told yes it would.Look...

Can I pay more on my device bill? So if my device bill was £20 and say one month I could pay £40 and then another month I could pay £60, could I just ring up and do that or can I not?I would really like to pay it off as quickly as I can.
