Example embodiments herein provide methods and Dual SIM Dual Standby (DSDS) devices including a first Subscriber Identity Module (SIM) and a second SIM for managing data communication. The methods include establishing, by the DSDS device, a Radio Resource Control (RRC) connection over the first SIM and performing data communication with a network entity. Further, the methods include detecting, by the DSDS device, an activity upcoming over the second SIM. Further, the methods include transmitting, by the DSDS device, a connection suspend indication to the network entity to suspend the data communication over the first SIM, wherein the connection suspend indication is transmitted on one of a Layer-1 control signaling channel, a Layer-2 control signaling channel, and a Layer-3 control signaling channel.
