Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM. The wireless device may obtain system information block (SIB) scheduling information associated with the first SIM, and may create a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time. Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap.
