Just apply for a telecom maintenance position. General telecom business halls will post recruitment notices. If so, apply. This position does not require high academic qualifications. If you are willing to endure hardships and use your brain to study, you can easily master relevant knowledge.

Generally, you will go out to work with your old colleagues after joining the company, and be familiar with the road and construction process (including receiving orders, contacting, preparing materials, on-site construction, completion after completion and receiving goods). When you get familiar with it, you will be responsible for all broadband installation and maintenance in a certain area in different regions.

But personally, if you have other jobs, don't do this. Very tired and the income is not high, the deduction is relatively high, there is basically no holiday, and there is basically no overtime pay for overtime work. I haven't learned much (at most, I have learned a network cable head, if I simply configure switches, optical cats and routers).

But if you like it, I suggest you learn some knowledge of computer maintenance, learn to politely refuse unreasonable demands from users, learn to make friends with users, and try to solve hidden dangers in advance to make it as easy as possible.
