RX nd TX refers to the radio frequencies the phone uses to receive and transmit voice calls. A mobile phone is essentially two 'walkie-talkies' operating at the same time - so you can talk and hear simultaneously. The handset transmits (TX) on one frequency, and receives (RX) on a different frequency.
