My original iPhone contract is due to expire and I want to use a PAYG or a monthly contract sim offer.. I text... a lot, so I want unlimited texts, 500+ minutes and unlimited data. I know O2 do bolt-ons and unlimited texts etc but is there any that have great deals? Might take a trip into town at the weekend and ask in store for their deals. Topup £30 a month on o2 and get unlimited texts and I think you get a free bolt on (internet..)? That then gives me £30 of calls. I don't mind that but if there's better... please let me know.
