A wireless communication device (5) used in a vehicle is configured to be capable of using multiple APNs in parallel, and includes a speed index acquisition unit (F2), a communication request acquisition unit (F31), and a path selection unit (F32), as functions. The speed index acquisition unit (F2) calculates a RSRP of a serving cell corresponding to each SIM 55. The communication request acquisition unit (F31) acquires a delay allowable amount indicating a length of an allowable communication delay time from each of in-vehicle devices (6) connected to the wireless communication device (5). The path selection unit (F32) allocates an APN which is relatively large in the RSRP among the wireless communication services to an in-vehicle device (6) that is relatively small in the delay allowable amount among the in-vehicle devices.
