Having had my fingers aka bank balance severely burnt by BT, Fresh,
Three and now Giffgaff overcharging, imposing hidden charges and plain
incompetance (like Giffgaff has just 'lost' my latest top-up) I have
decided that I do not trust any telcos to bill me correctly. Therefore
I am seeking a replacement for when my Fresh account expires at the
end of March. So far the only PAYG telcos that offer itemised billing
seems to be *Lycamobile, Virgin and Giffgaff. Of these I am leaning
towards Lycamobile - however a minus point is that at present it is
not possible to port an existing number over to them. Any advice
please? Many thanks - CJB.

Family Mobile also has itemised billing

giffgaff doesn't yet, that I know of
