previously check the phonebook memory status of ur sim it might be full some old simcard provides very less contact storage varies from 10 - 250 for newer sims
if sim is full then u can not copy contacts in it
or if it is not though then u can check ur sim by copying contact from inserting it in another phone if it works then ur mobile is faulty
Or
check it vice versa
if this is helpful let me know regards
