Method for Transferring Data from a Plurality of SIM-Less Communication Modules

摘要

The invention relates to a method of transferring data from at least a first communication module and a second communication module to, respectively, a first data processing centre and a second data processing centre via a circuit switched telecommunications network. A first and second connection request containing respective first and second pre-provisioned telephone numbers from the first and second communication modules are received in the network. The first and second telephone numbers are processed such that the network refrains from authenticating the first and second communication modules. Subsequently first and a second circuit switched data connections are established with the first and second communication modules for receiving data. The data can be routed from the first communication module to the first data processing centre and from the second communication module to the second data processing centre in accordance with the first and second telephone numbers, respectively.
