2SIM 3G GSM modem with automatic switching between SIM cards, from by manufacturer

Automatic switching between SIM-cards depends on the combination of stability of the correction stream and power of GSM signal, unlike most modems. Therefore, ModemOC creates a reliable channel for correction information stream.

The built-in Rx/Tx 2W UHF modem with a frequency range of 410-470 MHz and support for the Trimtalk 450S and Transparent protocols allows you to use the ModemOC as a normal UHF modem.

Intelligent selection of the most reliable stream of corrections between GSM1, GSM2 and UHF - type of communication automatically switches depending on the presence or absence of UHF signal or GSM network.
