A wireless communication system may support two types of networks, such as a 4th-Generation (4G) network and a 5th-Generation (5G) network. An LTE base station can be configured to broadcast information regarding whether it supports Non-Standalone Architecture (NSA) dual-network connectivity in conjunction with an associated NR base station. A communication device may use one of multiple strategies to determine whether 5G services are actually available at any particular time, and may display a corresponding network technology symbol when 5G services are accessible. The multiple strategies may be stored in non-volatile memory of the communication device. Policy information received from the communication system may specify which of the multiple policies is to be the active strategy, so that the network provider can change strategies without needing to perform a firmware or software upgrade.
