Esp8266 and Sim800l

Hi! I made a project with esp8266, Sim800l, MQ2.
When the SIM800l sensor is triggered, a certain number rings.
The problem is that when the power is turned on, the esp8266 does not work immediately. That is, you need to press the reset button.
What can I do to make Esp8266 work immediately without pressing the button, how to solve this problem?)
