Ozeki SMS Gateway configuration for 8-port GSM modem pool (video tutorial)

This video shows you how you can configure your newly setup 8 port modem pool to be used with Ozeki SMS Gateway. In this video we use an 8-port modem pool, which is automatically detected as the port by the Autodetect system. We then repeat this for all 8-ports.

The following document gives information on how to setup GSM modem pools with Ozeki 10 SMS Gateway. These devices allow you to send SMS through SIM cards. If you wish to send SMS messages through SIM cards, maybe a better alternative would be to setup Android phones using the Ozeki Android Client. They can be connected to Ozeki SMS gateway through the network (for example the Office Wifi. There are dual sim Android devices, and by connecting four of them, you get the same 8 phone numbers the modem pool would offer.

The reason we recommend you the Android SMS gateway option, is because the Android phones support messaging over 3G, 4G and 5G networks, and the modem pools only work on 2G. The 4G and 5G networks are significantly faster in terms of SMS messaging. Another problem is that 2G networks are being phased out in many countries. The mobile network operators will not provide 2G services in the near future to allocate frequencies to 4G and 5G.

Set up your 8-port GSM modem pool

The first step of setting up your modem pool is to insert a SIM card into one or more ports. The SIM card can be plugged into the modem as Figure 2 shows.

Next, you need to connect the antenna to the ports that have a SIM card inserted into. You can connect the antenna right after you removed the cover like in Figure 3.

To use the modem pool, next you have to connect it to a light socket with a power cable. As you can see on Figure 4, the power cable can be connected to the modem pool easily.

After you connected the modem pool to the power supply, you just need to turn on the modem pool by switching on the button as you can see it on Figure 5. If your modem is under power, the button lights up.

Next, you need to turn on the selected GSM port as well like in Figure 6.

The connectivity of the ports can be checked easily by the blue light next to the antenna (Figure 7). If it starts to blink, the SIM card connected right.

The last step of the setup process is to connect the modem pool to the PC. For that, as you can see on Figure 8, plug the USB cable into your modem pool.

To finish the setup, just insert the other end of the cable into your computer (Figure 9).

Configure the modem pool with Ozeki NG 10

Now your modem is ready to be configured. The first step you have to fulfil is to open Ozeki NG 10 on your desktop (Figure 10).

Next, log in with your Ozeki NG 10 account by typing your username and password as you can see on Figure 11 This account has to be created during the installation process.

The next window lists you all the connections that you can create in the SMS Gateway application. Now, as Figure 13 demonstrates, you have to select the SMS modem connection by clicking on Install.

In the installation menu, you need to select the port, where you connected the modem. For that, just click on the Autodetect button as you can see on Figure 14.

This Autodetect option will detect your modem, and if it is connected right the following window should show up like in Figure 15.

You can do this process with all the other ports, so like in Figure 16, you can manage maximum eight SMS modem connection at the same time.

Send an SMS message using the 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 17) by turning on the switch button in the connection details window.

To send the SMS message, you need to type the phone number of the recipient (Figure 18) in the Recipient field.
