Finally, solved garbage symbols in serial monitor by lowering the ESP's baud rate from 115200 to 9600 with the following command: AT+UART_DEF=9600,8,1,0,0 The root cause of the problem is speed limitations of the SoftwareSerial. On hardware Serial connection, it should work ok with speeds up to 115200.

There is my ESP AT+GMR info:

AT version:1.3.0.0(Jul 14 2016 18:54:01)
SDK version:2.0.0(5a875ba)
v1.0.0.3
