Did Bird's mobile phone go out of business? How come I didn't see it in a physical store, but there are many online?

This is the dilemma of domestic mobile phones.

When people choose a machine, they think of a fake machine besides a foreign brand.

No one will think of domestic brand machines.

The same is true for mobile phone manufacturers, so no one is willing to open the monopoly of domestic mobile phone manufacturers. Even agents have lower profits than cottage machines and lower sales than foreign brand machines. . . . . . .
