"O2 announces Pay & Go Go Go, a new tariff that gives customers more and more benefits the longer they stay on it. In a time when customers are looking for more from the brands they trust, O2 has reinvented Pay & Go to show its commitment to its customers.
The tariff, available today from O2 stores or at
www.o2.co.uk/payandgogogo, has two versions – one costing £10 a month and one costing £20 per month. Whichever version a customer chooses, it’ll regularly improve with bigger bundles, rewards or other incentives."
