Looks like the £1 per day Orange Extra is only for pay-as-you-go customers.
For monthly customers it looks like you can pay £5 for a month of evening & weekend unlimited data. Evenings end at 11:59pm - not 7am. Out-of-bundle daytime use seems to be £1.50 per MB capped at £1.50 per day. (I think that means £1.50 for unlimited data for the whole day, provided you'd bought the £5 bundle.) If you can normally restrict yourself to evening use, then the £1.50 cap is OK for occasional daytime use (and mistakes), but for regular (over 16 days per month) daytime use it might be cheaper to use a separate PAYG phone. Does anyone have any experience of this Orange bundle - how to buy it, and whethere I've got the figures right? Seems amazingly well-hidden on the Orange website. Dave Wedd
