This comparison focuses on hardware SMS gateways in the “single modem” category—standalone devices with an integrated mobile modem for sending/receiving SMS without using third-party cloud services. We’ve selected features that reflect real usage needs for such devices: network compatibility & connectivity, interfaces & configuration options, throughput & performance, and integration capabilities. These traits help compare device capabilities objectively based on how they impact deployment, reliability, and integration ease.
