NTT DoCoMo joined the million-plus battery recall party late last year, and now it has started a new party all its own -- recalling SIM cards en masse. The Japanese carrier said that it would be recalling 240,000 SIM cards for existing subscribers due to roaming problems with the cards. The carrier said that the recalled SIMs could malfunction when trying to be used outside of Japan (read: abroad), making the accompanying handsets useless for talk or data. New SIM cards are coming to the affected handsets for free, so the next time you take that i-mode handset somewhere outside NTT DoCoMo's area to not work, make sure you've swapped that SIM first, okay? Otherwise, you may get mad while roaming and take lighter to card.
