UART_RXD has been pulled down with a 15kR resistor to ground in module.
Note:
USIM DATA has been pulled up with a 22kR resistor to V_USIM in module.
IIC_SDA and IIC_SCL have been pulled up with two 2.2kR resistors to 2.6V in module.
So there is no need to pull them up or down in your application circuit.
