SMB128 is a SIM Box for 128 SIM cards, communicates directly with GoIPs with no SIM cards installed onboard. It allows centralized management and safekeeping of SIM cards. Hot swapping of SIM cards are supported so that no service interruptions to other SIM cards are incurred. SIM cards can be assigned to GoIP channels manually or dynamically with scheduled re-allocation algorithms. Therefore, SIM cards can virtually be moved between GoIP channels that are installed in different locations. In addition, SIM cards can be disabled based on certain triggering conditions and spare SIM cards can then be assigned to those GoIP channels. This mechanism helps to protect SIM cards from blocking and maximize the GoIP channel utilization.

 1) SIM Bank mode: server mode


As shown in the above figure, several GoIP devices (up to 128 ways) can be connected to the SMB128 through Internet. The SIM cards installed with the devices are all integrated to the SMB128 to be controlled and scheduled by the latter.


2) SIM Bank mode: client mode


More than 10,000 SIM cards can be collectively scheduled and managed via the SIM Server. The planned tasks are allocated by the SIM Server.


3) SIM Bank mode: schedule mode


The card numbers of the remote-end devices corresponding to the cards on the “schedule mode = fixed mode” slots.


When schedule mode is used (schedule mode = schedule), devices of different zones will automatically exchange their SIM cards when it is time for schedule, so as to realize the automatic roaming of SIM cards. When this configuration is used, chaos mode is adopted for the relationship between the SIM cards and the remote-end devices.
