Can I keep my airtime and data when switching to nano sim on PAYG
I've bought a new phone which requires a nano sim (my old phone is a Samsung S3 mini).
If I order a new sim will the airtime and data be transferred from my old sim? I'm on PAYG and I'm trying to figure out if it's worth topping up with £10 before the end of the month to get the free 2gigs of data for next month.
From what I understand I'll also have to pay £5 for the new sim - is this correct?
