Get the parts that you need to connect the modem successfully

To connect the modem successfully, you need a SIM card, an antenna, a USB cable and the modem itself to set up your Ozeki SMS modem to your PC. (All shown in Figure 2) Make sure that you have all the hardwares that you need to use the modem because every little detail is important.

Insert the SIM card into the modem

The first step that you have to perform is to plug the SIM card into the modem. This procedure is similar to inserting a SIM card to a mobile phone. The SIM card makes the connection between the modem and the network. (Demonstrated in Figure 3)

Important settings for SIM card

These settings are very important, and if you do not finish these, your SIM card won't work with Ozeki Gateway One. You must disable your PIN code and redirect phone calls to another phone number. You can do these steps on a normal mobile phone(Figure 4)

Connect the antenna to the modem

After inserting the SIM card, you have to connect the modem to its antennas. Make sure that it is connected correctly in order to get best performance. The function of the antenna is to transmit and receive signals. (Shown in Figure 4)

Insert the USB-C cable into the modem

The next step is to insert the USB-C cable into the modem. This will supply power to the modem from the computer, so it is advised to use a perfectly working cable to avoid disconnections. (Figure 5)

Insert the USB-A cable into the modem

Insert the USB-A cable into the modem. This will connect the modem to your computer, so it is advised to use a perfectly working cable to avoid disconnections. (Figure 6)

Plug the USB cable into your computer

Lastly, the other ends of the USB cables have to be connected to your PC. Plug them into your computer (As you can see on Figure 7)

The next window lists you all the connections that you can create in the SMS Gateway application. Now you have to look for the Wireless connections install list and select the SMS modem install item by clicking on the Install link. This will allow you to use the modem in the Ozeki SMS Gateway. (Demonstrated in Figure 12)

Set a name for your modem

You have to set a name for your Modem. You can leave the default value as well, but it's recommended to set a good name so you can distinguish modems easily. (Figure 13)

Select the Port

Once you have decided what name to set for the Modem, you have to select the Port of the modem, you will have to look for "Ozeki Modem Port", if it's not showing, check if you have installed the drivers correctly and try to flip the USB-C connector (Figure 14)

Autodetect properties

In the installation menu, at the General tab, you can find the Serial port groupbox. In Port combobox you need to select the port where you connected the modem. For autodetection, just click on the Autodetect button. The Autodetect button will recognize your device if it is connected properly. (Figure 15)

Check the information

This Autodetect option will detect your modem, and if it is connected right, the following window should show up with information about your connected modem and SIM card. You can check in this window that every detail is right with the hardware and the SIM card, just to make sure that you are using the proper hardware. Click the Ok button if you finished reading. (Figure 16)

Select the SMS options next to General option, so you can start configuring your Dual SIM modem (Figure 17)

Open Dual SIM settings

Set second SIM card number

Enter your second SIM card's phone number, you can find this on the package you received your SIM in (Figure 20).

Set the receive mode

For this setup, I recommend to set the modem into the "Receive on both" option, so you can see in the events when it changes networks. Receive mode is responsible for how the modem handles incoming text messages. The Ozeki SMS Gateway has 4 receive modes for dual sim modems that can use both of the SIM cards or just one. (Figure 21)

• Receive on both changes SIM cards every minute, text messages may appear a bit late.
• Receive on SIM1 will only show messages sent to SIM1.
• Receive on SIM2 will only show messages sent to SIM2.
• Receive where last sent will only show messages sent to the SIM that was last used for sending messages.

Finish the installation

Once you are done with setting up the modem, you have to click the Ok button at the bottom to finish setting up the modem (Can be seen on Figure 22)

Enable SMS Modem Connection

At this point, you have an SMS modem connection in the SMS Gateway application. To handle SMS messages with this connection, first, you need to enable the connection (Figure 23) by turning on the switch button in the connection details window. The green color shows that you enabled SMS modem connection. Important to note that you can't ignore this step because it is required to have an enabled connection to send SMS.

Check if you have a connection

If you can see both SIM cards, SIM1 and SIM2 connect to the network and have a good signal, you are good to go, you can proceed to the next step. This step may take a few minutes. (Visual aid is on Figure 24)

Navigate to the Test panel

You can send test messages on the Test panel to specified recipients, to select, look for the option "Test" at the top of the SMS Gateway details panel (Seen on Figure 25)

Fill the recipient's address and test message

After you enabled the connection, opened the Test tabpage. It has a General tab, select it and you will find the Recipient and SMS groupboxes. To send the SMS, you need to type the phone number of the recipient into the To: textbox. After that, just type the test message to the SMS groupbox. This message will be sent as an SMS to the previously given address. You can write whatever you want. (Figure 26)

Send the SMS

If you are ready to send the SMS message, just click on the Send button (Figure 27).

Check the test message

If you did everything in the right way, the message will be received by the recipient, as you can see in the test phone. This message is a simple SMS, just like the ones that you would get from other people. This shows you that you are ready to use the Ozeki SMS Gateway and the Ozeki Modem for your purposes.
