you have to say to them 4p a text and 8p a call per min. It's more of a general query of why do we just say 4p a text instead of 4p for 160 characters like you would do a phone call 8p a call per min. Hope this makes sense
I suppose because 'a text' is a quantifiable item in itself: its a fixed amount, while 'a phone call' has no fixed quantity so you have define a way of pricing it, so we have per minute.
If GiffGaff disconnected you at the end of a minute and you had to redial the number to carry on your conversation, then you could say it is 4p per text, 8p per call; but I think I'll just put up with saying call per minute

Technically, if a message is sent that's over 160 characters, it's sent as two or more separate texts, (at 4p each) with hidden joining characters in each, and the recieving phone pieces them together again
