Abstract: Various embodiments provide methods for a multi-Subscription Identity Module (SIM) wireless communication device for managing data exchanges with a network when an enhanced dedicated channel is requested on a first subscription. The methods may include performing operations during a testing phase to determine whether an enhanced dedicated channel grant is valid after a tune-away to a second subscription is completed, while transmitting data using the enhanced dedicated channel presuming that the enhanced dedicated channel grant is valid during the testing phase. The methods may include recording a list of protocol data units (PDUs) corresponding to data transmitted using the enhanced dedicated channel during the testing phase. The list of PDUs may be cleared and data exchanged with the network in response to determining that the enhanced dedicated channel grant is valid. Otherwise, the multi-SIM wireless communication device may request another enhanced dedicated channel grant.
