Hot Plug SIM Changer
The Hotplug SIM changer allowes you easily to exchange faulty or broken SIM cards externally. There is no need to power down the server and plug out the GSM card.
Additionally just like the SIM Bracket the Hotplug SIM Changer lets you use 4 more SIM cards for the quadGSM® card,
giving you a total of 8 SIM cards to be controlled by the driver.
