Oh yes, nearly forgot. SFR also offer a 24 hour pass for €8. Which is surely better than €39 for 15 hours right? Wrong. Not in France. The 24hr pass expires at midnight on the day you buy it! So if you buy it at 10 AM you get 14hrs usage before it expires - buy it at 8pm and you get 4 hours usage! So why do they call it a 24 hour pass?
