i want a way of storing upto 700 phone numbers on a mobile phone sim card, in the phonebook (nokia phone). i have seen blank sim cards that can store 250 numbers and can have upto 12 different operators, it's like having 12 sim cards on one. I'm thinking if they didn't waste all the space on the multiple operator function maybe there would be enough space for around 700 numbers. Even if i had a seperate sim card that i put in the phone that had only the phone book on it and i couldn't use it for calls maybe that would give me enough space.Or if i had a mmc card externally from the phone that was linked to a dummy sim. Is any of this possible ??
