Why is it difficult to open a hot spot for others? It is very likely that your traffic is not very abundant and not very good, so it will be very stuck. If not, there must be something wrong with your mobile phone. After opening a hot spot for others, your mobile phone is stuck. It must be the cell phone. This can't be anything else, because your mobile phone won't get stuck as long as you give someone a hot spot. If your mobile phone doesn't work normally, it must be that your traffic is not enough or not so much, so your mobile phone card is lost.
