Electron Cellular off mode

Hello, I have a Problem. When I flash one firmware into my electron it goes into cellular off mode and starts breathing white but this happens just in one code, when I flash any other code it doesn´t happen this. I don´t have any cellular.off(). Don´t know what the problem could be Thank you

Show your code, and we may spot the reason instead of just listing out any possible reason - which may apply or not - we can think of.
