Spanish operators have blocked some three million prepay SIM cards from making or receiving phone calls pending their owners registering their ownership details. Users of the unregistered SIMs will get an automatic message played when trying to make a phone call instructing them to visit a local retailer.

The operators were due to completely cut off the phones, but a last minute agreement by Interior Minister Alfredo Perez Rubalcaba, gives the SIM card owners up to six months to register their ownership before the lines go dead - and losing any prepay credit they may contain.
