This ICASA approved GSM voice and data repeater, with its high 70 dB gain, is ideal for use in areas where cellphone signal reception is poor or out of reach. With its dual band 900 MHz and 1800 MHz capability, it boosts all relevant technologies the network provider has available within these bands in your area (i.e. 2G, 3G or 4G – GSM900, UMTS900, LTE900, LTE1800 etc.) It is non network-locked and therefore usable with MTN, Vodacom and Cell C (not suitable for use with Telkom).
