What Are SMS Modems and How Do They Work?
SMS modems are USB or GSM devices that connect multiple SIM cards to computers for bulk messaging. They use AT commands to send/receive texts via cellular networks, ideal for high-volume campaigns without API dependency.
SMS modems, often called “SMS cat pools” in some markets, plug directly into USB ports on laptops or desktops. Unlike software-only solutions, they leverage physical SIMs for direct carrier access, bypassing throttling. Telarvo’s models support USB 2.0/3.0 for flexible deployment.
Key components include:
-
Wireless modules: Handle GSM/4G signals.
-
SIM slots: Up to 8 per pool for parallel sending.
-
Power management: Ensures stable operation during peaks.
This hardware excels in regions with strict API regulations, offering cost-effective bulk SMS at scale.
