I have a plain payg sim for a smartphone. I don't use it for calls or texts but might want occasional access to 3g.
I am trying to understand the charge. It says "£3/MB up to max £1/day"
OK, if I connect it immediately deducts £1. On the face of it that means my £1 gives me 0.3MB. Is that correct?
What does it mean by "max". A data limit or just remaining credit?
Also, once I have made a connection, does it remain true payg or does unused credit get lost after so many days?
