A network device may receive, from a sending device, a message in a first messaging format en route to user equipment. The first messaging format may correspond to one of a 3GPP cellular network standard or a 3GPP2 cellular network standard. The network device may determine whether the user equipment is associated with the first messaging format or with a second messaging format. The second messaging format may correspond to one of the 3GPP cellular network standard or the 3GPP2 cellular network standard. The first messaging format and the second messaging format may be associated with different cellular network standards. The device may selectively provide the message in the first messaging format or the second messaging format based on whether the user equipment is associated with the first messaging format or the second messaging format. The device may transmit an acknowledgment message based on the first messaging format.
