Some mobile phones support use of two SIM cards, described as dual SIM operation. When a second SIM card is installed, the phone may allow users to switch between two separate mobile network services manually, have hardware support for keeping both connections in a "standby" state for automatic switching, or have two transceivers to maintain both network connections at once.
Nokia's strategic nomenclature can be traced back in 2005 when the Nseries line was launched, offering devices with flagship specifications and premium hardware at various price points. These devices were considered the "bread and butter" of the company and were often positioned to showcase their latest technologies. Thanks to the newfound consumer and enterprise interest in smartphones at the time, the company introduced four additional collections to diversify their product portfolio and meet demands in most market segments. These new phone series were named Eseries, targeting small business and enterprise customers; Xseries, providing consumer-grade multimedia-focused devices; Cseries, which Nokia used to target both the low-end and mid-range market segments; and Tseries, for devices exclusive to the Chinese market.
