How does a Dual SIM modem work?

The Ozeki 4G Modem Dual SIM provides the advantage of utilizing two distinct SIM cards. When sending a message, our software intelligently selects the appropriate SIM card based on the Sender ID. This dynamic approach enhances cost-effectiveness by optimizing message sending costs. Additionally, this setup offers increased fault tolerance and redundancy, as two SIM cards provide a backup solution in case of any issues.

How sending SMS through a 4G modem works

This SMS sending solution makes it possible to send SMS messages from a computer. This solution uses a few components: a computer equipped with the Ozeki SMS Gateway software, an Ozeki modem, and the recipient's mobile phone. The computer, hosting the Ozeki SMS Gateway application takes on the role of assembling the message, requiring both an address and a text body. The SMS message is sent through the Ozeki SMS modem, which communicates with a service provider.
