A system for facilitating carrier-specific configuration of user devices based on pre-stored limited access information for multiple carriers, the system comprising a user device that includes one or more physical processors programmed to execute computer program instructions which, when executed, cause the user device to: store information for limited access that allows the user device to obtain carrier-specific parameters for configuring the user device via carrier networks of different carriers, wherein the stored limited access information comprises a multi-carrier-recognized access point name that is recognized by the carrier networks of the different carriers for obtaining the carrier-specific parameters for configuring the user device to operate on a carrier network of the different carriers; select, during activation of the user device, one of the carrier networks on which the user device is to be configured to operate, the selected carrier network being a carrier network of a first carrier; responsive to the selection of the carrier network, provide, to a carrier-side computer system on the selected carrier network, a request for limited access to the selected carrier network for configuring the user device for the selected carrier network, wherein the limited access request comprises the multi-carrier-recognized access point name of the stored limited access information that allows the user device to obtain carrier-specific parameters for configuring the user device via the selected carrier network; responsive to the limited access being granted by the carrier-side computer system, obtain, from the carrier-side computer system, a configuration package comprising one or more of the carrier-specific parameters for configuring the user device for the selected carrier network; and cause, based on the obtained configuration package, the user device to be configured for further access to the selected carrier network. store information for limited access that allows the user device to obtain carrier-specific parameters for configuring the user device via carrier networks of different carriers, wherein the stored limited access information comprises a multi-carrier-recognized access point name that is recognized by the carrier networks of the different carriers for obtaining the carrier-specific parameters for configuring the user device to operate on a carrier network of the different carriers; select, during activation of the user device, one of the carrier networks on which the user device is to be configured to operate, the selected carrier network being a carrier network of a first carrier; responsive to the selection of the carrier network, provide, to a carrier-side computer system on the selected carrier network, a request for limited access to the selected carrier network for configuring the user device for the selected carrier network, wherein the limited access request comprises the multi-carrier-recognized access point name of the stored limited access information that allows the user device to obtain carrier-specific parameters for configuring the user device via the selected carrier network; responsive to the limited access being granted by the carrier-side computer system, obtain, from the carrier-side computer system, a configuration package comprising one or more of the carrier-specific parameters for configuring the user device for the selected carrier network; and cause, based on the obtained configuration package, the user device to be configured for further access to the selected carrier network.
