Sounds worrying but then again, MSE is not a site I’d trust too far for the impartiality/completeness of news coverage. I’d like to hear the other side of the story, if there is one.
I actually like PAYG, mainly as there’s no arduous contracts with acres of small print, and no possibility of suddenly finding your account’s been debited masses of cash either through accidental use or fraud. It’s also easier to see the wood from the trees regarding the actual costs, over a few years, of buying and running a phone.
I’m with Vodafone which sells PAYG “bundles” that you can automatically opt into, as long as there’s enough balance when payment becomes due. My £10 monthly bundle gets me 3GB data, 250 minutes and unlimited texts, which is more than adequate for me, in all respects.
