UART1 UART2 ESP8266

Hello!
Is it possible to use UART 1 or UART 2 on an ESP8266 NodeMCU?
I want to use for communication between the ESP8266 and a SIM808.
When I use phone = UART (2, 9600), it gives me an error that the port does not exist, when I use phone = UART (1, 9600) it replies that it is inaccessible.
When I use phone = UART (0, 9600), there is no error, but it complicates my communication with the terminal.
