Thanks for the link... need to sort out the wifes contract. I had no idea what she was paying for her sim only deal. 6 months later, turns out it's £30 a month. Unlimited data, but £30!?
I currently pay £13 a month for 27gb data with EE (includes a boost for having home BB with them) and also BT sport. Given i'm wfh for the foreseeable and therefore on wifi, I'm sure I could reduce it a bit now.
