Get the parts that you need to connect the modem successfully

For a successful connection of the modem, it's essential to have a SIM card, an antenna, a USB cable, and the modem itself. All these components are depicted in Figure 2. Ensuring that you possess all the necessary hardware is crucial as every detail plays a significant role in the functionality of the modem setup.

Insert the SIM card into the modem

The first step is to insert the SIM card into the modem, a process similar to inserting a SIM card into a mobile phone. The SIM card establishes the connection between the modem and the network, enabling communication. (Demonstrated in Figure 3)

Important settings for SIM card

It is crucial to pay close attention to these settings, as failing to complete them could result in your SIM card not functioning with Ozeki Gateway One. You need to deactivate your PIN code and forward phone calls to an alternative phone number. These steps can typically be carried out using a regular mobile phone. (Figure 4)

Connect the antenna to the modem

Once the SIM card is securely inserted, the next step is to connect the modem to its antennas. Ensuring a proper and secure connection is crucial to achieve optimal performance. The antennas play a vital role in both transmitting and receiving signals, so proper attachment is essential for effective communication. You can refer to Figure 5 for visual guidance on how to connect the antennas correctly.

Insert the USB-C cable into the modem

Moving forward, you'll need to insert the USB-C cable into the modem. This cable serves as the power supply for the modem, drawing power from the computer. It's crucial to use a reliable and fully functional cable to prevent any disruptions or disconnections during the setup process. You can find a visual representation of this step in Figure 6.

Insert the USB-A cable into the modem

Continuing with the setup, insert the USB-A cable into the modem. This cable establishes the connection between the modem and your computer. It's essential to use a high-quality cable that's in proper working condition to prevent any potential disconnections or interruptions. You can refer to Figure 7 for a visual representation of this step.

Plug the USB cable into your computer

Connect the other ends of the USB cables to your PC. Plug each end of the USB cables into the corresponding USB ports on your computer. You can refer to Figure 8 for a visual representation of this step.
