or computer) and emergency services. The 4G LTE adapter will also provide a wireless Wi-Fi Internet connection, similar to that of the embedded OnStar systems found in newer General Motors vehicles. Owners of certain vehicles not compatible with the 4G LTE adapter will lose access to all OnStar services, though they will be able to download the OnStar Guardian mobile application onto their iOS or Google Android smartphone that will provide similar functionality to their vehicle's CDMA-based OnStar system. OnStar has also announced that, effective February, 2022, the built-in hands-free cellular telephone functionality, which allowed drivers to make and receive voice-activated, hands-free phone calls over their vehicle's car audio system, and assigned the vehicle a unique telephone number, will be discontinued, citing the increased popularity of Bluetooth connectivity in most vehicles. This affects all OnStar-equipped vehicles, regardless of cellular technology or model year. Certain early AT&T 4G LTE-equipped OnStar vehicles will be required to install a Firmware Over The Air (FOTA) software update that will allow their vehicles to connect to an updated 4G LTE cellular network. Affected vehicles must have active OnStar services in order to install the software update.
