AT&T today quietly began offering a SIM card option to its collection. The new choice provides buyers of the US-edition N95 8GB and other unlocked phones the option of joining AT&T's network without first choosing a device, potentially reducing the cost of entry. Each SIM card supports most any feature supported by existing devices and will connect to AT&T's 3G service as well as supply either prepaid or subscription access depending on the user's needs.

A SIM with 64K of memory for customer information costs $10 at a store or $5 online and is not changed in price by contracts or other discounts; AT&T allows customers to port phone numbers from other US carriers to their individual SIM card but is not expected to allow the iPhone and other carrier-specific devices to work with the new SIM.
