Techniques for configuring data in a subscriber identity module (SIM) of a user equipment (UE) via over-the-air (OTA) configuration messages are discussed herein. An OTA server may receive, from an operator associated with a telecommunication network, identifying information specifying a UE or a group of UEs in which to send the OTA configuration and may receive an indication of a type of configuration to be included in the OTA configuration. The OTA server may access an equipment identity register (EIR) to determine which UEs to receive the OTA configuration message based on the identifying information.
