A system, method, and computer-readable medium provide for determining that a user device does not include a subscriber identity module (SIM) profile activated to provision a wireless service of a first mobile network operator (MNO); obtaining location data for the user device; generating multiple mobile network codes (MNCs) and corresponding public land mobile network (PLMN) identifiers (IDs) for multiple MNOs that service an area associated with the location data, wherein the multiple MNOs include the first MNO; configuring, using the PLMN IDs, a radio frequency (RF) channel associated with each of the MNOs using each PLMN ID; generating temporary device IDs for the user device; transmitting a discovery message including each device ID via the RF channel associated with each MNO; receiving from the first MNO storing a reserved SIM profile for the device ID, a network address; and downloading the reserved SIM profile via the network address.
