Methods, systems, and devices are described for transitioning between different radio access technologies (RATs) utilizing system information messages to trigger the transition. Some embodiments may involve utilizing a system information message (e.g., SIB19, SI2quater) that may be received from a serving cell over a first radio RAT (e.g., 2G, 3G, 4G) while in a connected mode with the serving cell. A transition may be initiated from the connected mode with the serving cell to an idle mode with the serving cell in response to the received system information message. A reselection may be performed from the idle mode with the serving cell to a target cell utilizing a second RAT (e.g., 3G, 4G, or 5G) in response to the received system information message.
