Long story short, old SIM cards "leak" power due to bad contacts and increased internal resistance [''citation needed'']. In addition, other users have mentioned that depending on their age, different SIM cards operate in different voltages (5V, 3V, 1.8V). The N900 has support for legacy SIM cards which means older SIMs will require more power.
