1. What is a SIM Bank?

A SIM Bank is a network device with the capability to read a bank for SIM cards and then communicates with GSM devices in order to establish virtual connections between SIM cards and GSM devices. This allows SIM Banks to be installed in one location whereas GSM devices are installed at different locations. This operation is referred as Remote SIM which is intended for centralized management of SIM cards. 2. Can SMB32 work with any GSM devices?

No, SMB32 can only communicate with HYBERTONE's VoIP GSM Gateways (GoIPs) with Remote SIM support.

3. Are there any SIM Card compatibility issues with SMB32?

There have been occasional incidences that SMB32 cannot detect some SIM cards or cannot register to their GSM Service providers. If you are encountering SIM card problem, please contact technical support for help.

4. How to insert or remove a SIM card?

To insert or remove a SIM card, the power to the SIM slot should be turn off first. If the slot LED is off, you need to press the push button to turn on the LED (green color). This turns off the power to the SIM slot and you can now insert or remove the SIM card. Please see the diagram below and note the orientation of the SIM card when inserting it into the SIM slot. Once you hear a click sound, the SIM card is in a lock position and you can then press the push button again to turn on the power. The LED is then turn off.


Please note that the first batch of SIM banks produced are using red color LED.

5. How do I configure a SIM Bank for standalone operation (not using SIM Server)?

You need to access the webpage of the SIM Bank and the webpage of the designated GoIPs individually.

a) Configure the SIM Bank to "Server" mode.

b) Set the ID and password for the designated GoIPs. Each GoIP must have its own ID.

c) Set the Area ID if needed. GSM Channel with different Area ID will be selected first during SIM slot re-allocation. Please refer to the SIM Bank User Manual for more information.

d) Select the number of lines for the designated GoIP. This tells the SIM Bank the number of GSM channels in the GoIP.

e) Access the webpage of each designated GoIP.

f) Enable the Remote SIM function in the designated GoIPs.

g) Set the "Server" address to the IP address of the SIM Bank.If the SIM Bank is installed behind NAT and GoIPs are not installed in the same network, the sever address is the public IP of the network where the SIM Bank is installed. The default communication port for SIM Bank is 56011. If different port is used, it should be specified in the address field as :xxxxx where xxxxx is the port number.

h) Set the "ID" and "Password" to the corresponding IDs and passwords defined for each machine (GoIP) in the SIM Bank.

i) Check the running status in the webpage of the SIM Bank. You should first check which SIM slot is assigned to which GoIP channel. If a SIM card is inserted in a SIM slot, the channel status of the corresponding machine should be either LOGIN or LOGOUT. If the machine (GoIP) is not online, all status of all channels of that machine is then "Offline".

6. How do I assign SIM cards to GSM channels (GoIPs)?

It is important to understand that the SIM allocation is not based on SIM cards. Instead, it is based on the SIM slots in the SIM bank. Therefore, changing SIM cards does not affect the SIM Slot allocation.

The schedule mode in the SIM Bank settings page defines how SIM slots are allocated to GSM channels.

a) Fixed - In this mode, the allocation of SIM slots to GSM channels is fixed. SIM slot 1 is allocated to the channel 1 of the Machine M1 and so on. If only GoIP-8 are used, only four machines (M1, M2, M3, M4) are needed to take up all 32 SIM slots.

b) Schedule - In this mode, the allocation of SIM slots to GSM channels is automatically done to by the SIM Bank. User has no control over this allocation. The re-allocation schedule is defined by the Work Interval and the Sleep Interval.
