A method is presented of establishing communications with a Virtual Machine, VM, in a virtualized computing environment using a 3GPPcommunications network. The method includes establishing a Machine-to-Machine Equipment Platform, M2MEP, which comprises a Communications Module, CM, providing an end-point of a communication channel between the 3GPP network and the VM. A virtual Machine-to-Machine Equipment is established that comprises a VM running on the M2MEP and a downloadable Subscriber Identity Module, associated with the CM. The Subscriber Identity Module includes security data and functions for enabling access via the 3GPP network. The CM utilizes data in the Subscriber Identity Module for controlling communication over the communication channel between the VM and the 3GPP network.
