Data SIM
Is it possible to buy a data only SIM and if so where please.
I don't want anything that renews every month as contracts, and seemingly Payg, do. I just want to buy a lump of data that I can use, as and when, until it's exhausted.
I've checked the usual suspects and some smaller suppliers to no avail and my local computer /phone shop tells me that it's not possible.
Any ideas?
