A method of providing network access to an in-vehicle infotainment system of a vehicle through a network access node pre-associated with that vehicle, the in-vehicle infotainment system being associated with a first unique network identifier, the in-vehicle infotainment system comprising hardware and software modules that are configured to facilitate internet access via a wide area network channel and to establish a WiFi hotspot for local area communications, the method comprising: receiving, at the network access node, in response to a triggered login request, a data request from a mobile device, the mobile device being associated with a second different unique network identifier, the data request being received over a first communication channel, the first communication channel using a packet switched network; extracting, by the network access node, from the data request, the second different unique network identifier and details of a mobile network operator that is associated with the second different unique network identifier; sending, by the network access node, in response to the received data request, a mobile terminated SMS message to the mobile device associated with the second different unique network identifier over a second communication channel, the second communication channel using a circuit switched network provided by the mobile network operator that is associated with the second different unique network identifier, the mobile terminated SMS message including an activation URL; receiving, by the network access node, from the mobile network operator, a confirmation of network delivery of the mobile terminated SMS message to the mobile device; associating, by the network access node, at the network access node, in response to receiving confirmation of delivery of the mobile terminated SMS message, the first unique network identifier with the second unique network identifier such that subsequent network traffic that is received at the network access node that originates from the in-vehicle infotainment system and is identifiable with the first unique network identifier is associated with an account that is associated with an MSISDN of the mobile device; initiating, by the network access node, in response to user selection of the activation URL at the mobile device, local WiFi services at the vehicle infotainment system; and enabling, by the network access node, network access services to the infotainment system of the vehicle. receiving, at the network access node, in response to a triggered login request, a data request from a mobile device, the mobile device being associated with a second different unique network identifier, the data request being received over a first communication channel, the first communication channel using a packet switched network; extracting, by the network access node, from the data request, the second different unique network identifier and details of a mobile network operator that is associated with the second different unique network identifier; sending, by the network access node, in response to the received data request, a mobile terminated SMS message to the mobile device associated with the second different unique network identifier over a second communication channel, the second communication channel using a circuit switched network provided by the mobile network operator that is associated with the second different unique network identifier, the mobile terminated SMS message including an activation URL; receiving, by the network access node, from the mobile network operator, a confirmation of network delivery of the mobile terminated SMS message to the mobile device; associating, by the network access node, at the network access node, in response to receiving confirmation of delivery of the mobile terminated SMS message, the first unique network identifier with the second unique network identifier such that subsequent network traffic that is received at the network access node that originates from the in-vehicle infotainment system and is identifiable with the first unique network identifier is associated with an account that is associated with an MSISDN of the mobile device; initiating, by the network access node, in response to user selection of the activation URL at the mobile device, local WiFi services at the vehicle infotainment system; and enabling, by the network access node, network access services to the infotainment system of the vehicle.
