Abstract
Systems and methods are disclosed herein related simultaneous registration of wireless communication device having multiple Subscriber Identity Modules (SIMs) with two or more networks. In one embodiment, a method performed by a wireless communication device having multiple SIMs comprises registering with a first network associated with a first SIM and registering with a second network associated with a second SIM such that the wireless communication device is simultaneously registered with both the first network and the second network. The method further comprises providing, to a network node associated with the first network, capability information for the wireless communication device that indicates less than full capabilities of the wireless communication device. In this manner, the wireless communication device ensures that it will have sufficient resources to maintain simultaneous connections to both the first and second network.
