翻译:也许你的手机不支持中文

Maybe Chinese is not supported in your cell phone.

我觉得maybe you phone doesn't support chinese。没有什么语法错误，把

phone改成cell phone,chinese的c大写，可以使用，但我觉得下面的更好一些

Maybe your cell phone doesn't support the use of Chinese.

maybe your phone can not recognize chinese

可以，但改一下 your cell phone
不是you phone
