SIM cards do not always work for any cell phone, as most wireless providers lock their phones to their specific network. Putting a SIM card into a cell phone locked to a different company usually triggers a service provider lock. Usually, the only way to get around this is getting the unlock code from the wireless provider it was originally used with, which they may not allow. In addition, some cell phones, usually CDMA, do not even have a slot for a SIM card.
