Your only option is the tills at the likes of B&M, Home Bargains or PoundLand, but the tariff and sim card are no longer officially on sale.. And some of the sims will have expired by now..
Not sure of the obsession of the big talker sim card as there are better offers from o2's MVNO customer LycaMobile https://www.lycamobile.co.uk/en/sim-only-deals/#/national
- Xperia 1V - o2 and Spusu
- Pixel 8 Pro - o2 and Vodafone UK
