I know some sim cards can be bought already with credit on and used to purchase stuff on the google play store. I bought two ee cards this week got me looking on ebay for more.
I found this sim card here: ebay.co.uk/itm…rue
Its an international sim card but from o2. Dont see why it wouldnt work as has £30 credit on.
If anyone knows if this would work that would be really helpful.
