Using a remote SIM card with Bluetooth wireless technology
1.Using a remote SIM card with Bluetooth wireless technology
The car kit phone supports Bluetooth wireless technology and Bluetooth SIM access profile.
yBluetooth wireless technology
Bluetooth wireless technology is an international standard for wireless
yBluetooth SIM Access Profile
Bluetooth SIM Access Profile is an industry standard which allows a device, e.g. a car kit phone, which supports Bluetooth wireless technology to access a SIM card in a compatible mobile phone over a wireless link. The car kit phone is then able to read and write data from/to the remote SIM card inserted in the compatible mobile phone and to log into the GSM network. A separate SIM card inserted in the car kit phone is not required in this case.
You have switched on a compatible mobile phone supporting the Bluetooth SIM Access Profile standard, a valid SIM card is inserted in the compatible mobile phone, Bluetooth wireless technology has been activated, the compatible mobile phone
has been paired with the car kit phone and you get into your car.
How the GSM/Bluetooth wireless connection works
When the car ignition is switched on, a wireless connection is established between the compatible mobile phone and the car kit phone via Bluetooth SIM Access Profile. The car kit phone requests the compatible mobile phone to log out of the GSM wireless network and to deactivate the mobile phone components required for the GSM connection. The car kit phone then uses Bluetooth SIM Access Profile to access the SIM card inserted in the compatible mobile phone (remote SIM card) and utilises this card’s profile to log into the GSM network. Now the car kit phone handles all incoming and outgoing calls and messages while accessing the SIM card of the compatible mobile phone.
