A method for a data session switching by a User Equipment (UE) is provided. The method includes monitoring network broadcasted parameters of a second Subscriber Identity Module (SIM) of the UE while performing a Fifth Generation Cellular Network (5G) data session over a first SIM of the UE, where the first SIM is configured for a Default Data Service (DDS), detecting that a trigger criterion is met for the 5G data session switching to the second SIM based on the network broadcasted parameters, and in response to the trigger criterion being met, configuring the second SIM for the DDS for continuing the 5G data session over the second SIM.
