How to find out the maximum number of contacts that the SIM card phonebook can hold?
European Telecommunications Standards Institute (ETSI) lays down standards for SIM

From 3GPP TS 21.111 version 8.0.1 Release 8 pertaining to 3G


  10.2.6 Number of entries : The specification shall support storage of at least 500 entries.


This does not mention the SIM storage size in relation to the number of entries

I was hoping to find a  correlation between size and entries and this is the only thing I could find.
