Why doesn't this phone come with a charger?
O2 is working to try and reduce waste. And as 70% of people already have a USB charger at home, we've decided to not include one with your phone. If you do need a charger you can add one after choosing your tariff. O2 does not make money from selling the charger separately.
For your everyday rituals, we've got offers like £1 lunch on Mondays. Fancy an every-so-often treat? Try getting tickets to that gig 48 hours before your friends. And then there's your chance to win once-in-a-lifetime experiences.
