Controlling a network node

Abstract

A network aggregator node 206 is communicatively couplable to: (i) a device 100 comprising a multi-network SIM; and (ii) wireless communications service provider networks 210, 212, 214. An access request is received from the device. A first wireless communications service provider is identified based on the access request. An attempt is made to authenticate the multi-network SIM with the first wireless communications service provider network. In response to successful authentication within a threshold time, a latency test is performed in respect of a communication channel between the device and the wireless communications service provider network. In response to the latency test indicating an acceptable latency, an authenticated connection is established between the device and the wireless communications service provider network. Figure 3
