inputting, at a user interface of a device, a voucher having a plurality of data fields, where the voucher provides provisional subscriber identification for the device;
sending at least some of the voucher data fields towards a network operator, where the data fields of the voucher comprise a first prepaid code;
receiving a request for additional information;
in response to the request, sending a response with the additional information, where the additional information is a second prepaid code that comprises one of the voucher data fields;
based on the second prepaid code being validated as corresponding to the voucher, receiving a software based subscriber identity module, where the voucher comprises at least one prepaid number code to form the software based subscriber identity module; and
using the software based subscriber identity module to authenticate the device and activate a subscription with the network operator for the device.
2. The method according to claim 1 , where the software based subscriber identity module provides an international mobile subscriber identity for the device.
3. The method according to claim 1 , where the data fields of the voucher comprise a mobile country code, and a mobile network code.
4. The method according to claim 1 , where the response is encrypted using a public key certificate for the device.
5. The method according to claim 1 , where the request for the additional information is received in a short message service message.
6. The method according to claim 1 , where the network operator is a visiting network operator, where the software based subscriber identity module is received from a home network of the device, and where communication between the device and the home network for the software based subscriber identity module is via the visiting network operator.
7. The method according to claim 1 , where the device comprises a mobile device, and where the inputting comprises inputting the voucher with the user interface by a user of the mobile device.
