From the context of your previous comments, it seemed like you were talking not about not having a mobile phone in general, but rather a SIMless phone. Using it over Wi-Fi only is indeed doable - but you’d need an Airplane Mode on an OS you can trust, just having no SIM would not be enough.
Also no, I did not have such a job - I don’t understand how this question relates to the conversation.
The queation pertains to having a sense from how someone talks if they sound like they can configure network services or if they only read about it but not having the skills/experience to work for random customers and explain the work to them.

Any AOSP ROM would suffice.
