Micro/Nano SIMs
 

Does anyone know which of the common prepaid providers are offering micro and nano SIMs in stores? For example, it seems that the o2 store at FRA only offers micro SIMs now, so thought it might be good to get a list going of what is/isn't available at places like Aldi/Lidl/Tchibo. Information on provider's websites usually only lists what is available online, so I thought it would be useful to post experiences here.
