If this is your first time in China or you haven't been here for a decade or longer, be prepared to re-learn how to do basic things, and what apps are needed for what.
I thought everyone coming here has working cell phones, but I suppose some of those who are joining new companies* might not have them. While your hotels will definitely have fast wifi, you will still receive 1 or 2 actual phone calls per day. More importantly, when you're released, you might score Y700 like I did, but actual cash is useless if your goal is to go somewhere else. I've heard that Didi has a freeze on new customers. If you don't have an account, you are welcome to message me and I'll pull it off.
*ETA: Your companies should definitely cover this trivial expense. The problem is that you will have no ability to get a SIM directly from Unicom or China Mobile when you're locked up. I can't vouch for Nihao Mobile myself, but if they can get you a SIM that adheres to government requirements (e.g. number, name, passport are bonded), and their value added fee is reasonable, try them out.
