By the way, when entering Montenegro from Serbia, does the Serbian bought phone card have no signal? Do I need to rent a WiFi egg again ?

Yes. There was no signal after I entered Montenegro with a Roaming Man last time.
I suggest opening a European package or a Belt and Road package for Wuxingxing, the signal is better. The phone card over there probably can't be activated by yourself, and even if it is activated, it will take half an hour before it can be used. After passing through, it can roam for a short time, but soon there is no signal.
