Hi,
My contract has ended and all payments have been made so i am eligible for an upgrade. I found the sim only deal i want (20GB, £15, 12 month) but when i proceed to the check out it says i am not eligible if i want to keep my number. The link for my upgrades gives a ridiculous "deal" of 15GB for a massive £35! How can i get the actual 20GB deal at a reasonable price instead of paying £20 a month more for less data without changing my number? I have been an o2 customer for over 12 years, i would hate to have to leave because if this is only available to new customers.
