A user device may receive an access request to access an application provided by a cellular carrier associated with the user device. The user device may use a first type of tunneling protocol to establish a connection, via an evolved packet data gateway (ePDG), to a server that provides the application; determines whether the connection is established using the first type of tunneling protocol; and use a second type of tunneling protocol to establish the connection when the connection is not established using the first type of tunneling protocol. The user device may also use the connection to access the application via the ePDG.
