When it comes to Boxing Day sales, O2 don’t do things by halves. We looked back over last year’s sale and found some impressive savings across major brands, with up to £600 off select iPhone, Samsung, and Google models.
During last year’s O2 Boxing Day sale, shoppers could snap up the iPhone 15 with 150GB of data, unlimited calls and texts on an O2 Plus Plan for £50.99 per month. Even with the £30 upfront fee, this meant a £108 saving overall.
The Samsung Galaxy S23 was also available with 150GB of data for £47.69 per month, meaning you’d have saved £288. Those looking to buy the Google Pixel 7 Pro could’ve taken advantage of a whopping £500 O2 Boxing Day saving. With 30GB of data, this deal was available for £37.86 per month.
