What if there is no third-party phone to fill in the mobile phone stock market? There is only one person. My friend won't let me use it.
Parents', colleagues' and classmates' names can be filled in, but they really can't. Take your ID card and open another number yourself. In fact, this third party can't contact you in an emergency, and the reserved phone number is just a backup, which is almost useless. Anyway, if you lose money, you will lose your own money, right? I wish you a smooth sailing.
