I want to go to Xishuangbanna, Lijiang and go to dali. My mobile phone is in a mobile dynamic area. I wonder where there is wifi in a four-star hotel. I still need it.

Now some more formal hotels will provide Weifei, don't worry. However, if you are not worried enough, you can open some traffic. Of course, moving is more expensive. It is ok to change to GSM, but the business change must be completed for half a year before it can be changed again, so you should consider this carefully before making a decision.
