Systems and methods for facilitating emergency call service are provided. The method can include modifying a configuration parameter of a user equipment (UE), wherein the configuration parameter is related to at least one of: network selection, cell selection or reselection or service selection within a wireless communication system, and wherein a modified configuration parameter results in a preference by the UE for a network, cell or service configured to support emergency calls at the UE. The method can also include prioritizing circuit-switched services over packet-switched services, utilizing the circuit-switched voice service preferentially or exclusively and/or prioritizing a network configured to offer emergency call service over the original serving network of the UE, based, at least, on the modifying the configuration parameter. Modifying the configuration parameter can be performed autonomously by the UE. The modified configuration can also enable callback services to a UE from the network.
