A SRLTE/Hybrid CDMA management system is provided to facilitate the prioritization and management of shared RF resources among the different SIMs and RATs in a multimode device. The described techniques address a shared single RF resource usage problem in multi-SIM and multimode 3GPP2/3GPP devices that implement an SRLTE or Hybrid CDMA mode in one or more SIMs. Thus, the techniques enable the RATs within an SRLTE or Hybrid CDMA system, and RATs across multiple SIMs, to access a single set of RF resources using a priority access scheme that prioritizes RATs for both packet service (PS) and circuit service (CS).
