Does your device plans have a separate direct debit to the airtime plan? My O2 contracts do and once my device ends I just continue to pay for the airtime plan at its standard charge.

I'm sure most networks do this now as they used to get in to trouble when contracts ended and if you didn't contact you'd be paying the £56 per month until you called them. Where as now my device is £38 a month and airtime is £15, so when device paid off I'm only left with the £15 until I decide to upgrade to a new device.

We used to get calls about it all the time when I was in customer relations at Vodafone. Suddenly calling 14 months after contract ended and wondering why still paying the full price. It was their responsibility to keep track of their service and contract terms.
