I've got a PAYG card on EE in my Ipad. Although I have not topped it p for about 3 months and I can't actually access the my EE area but when i went to try last night I noticed my ipad refresh an old webpage so it's just working. No idea why or how but it is.
Anyone else have an old PAYG sim they can test? afaik EE aren't doing just free 4G?
