# You might have to get a new SIM Card. (1) Did you buy it from a carrier? They might’ve rooted the phone to prevent other carriers from working. (This happened to me) (2) can u still text? (3) heres a link to ZTE’S user manuals https://www.zteusa.com/support_page
Try to jump start your fan by pushing it with your hands after starting it. If that doesn't work, then check the fan's wiring- find an electrician, or call the fan's company and check if you still have warranty.
To assess your problem, open up the back and check for the following: 1. It has water damage >>>>> buy a new one, fixing it will cost more. 2. >>>>> It has taken physical damage ( dropping it, sitting on it, etc. ) buy a new one. It will take a fortune to replace the internal components now.
