网友问题: 在美国买的手机国内能用么? 另外, 请推荐款unlocked的手机回国给父母用的, 便宜好用即可.
一般LG的Android手机都自带中文菜单，不需要刷机; HTC的内置隐藏中文菜单，用MoreLocale2就能调出来，也很简单; Samsung的手机比较麻烦，要刷机，一些内置的app没有汉化.
如果是带给父母的，建议买4.3 inch以上480 x 800 pixels分辨率的手机, 字体大小比较合适老年人看. phone的字体太小，年纪大的人不带眼镜看不清楚。这款 LG Optimus L7 P705 Black Factory Unlocked
是4.3 inch的，review还可以, 可以作为参考.
另外，HTC的 HTC Inspire
和三星的 Samsung Infuse
What is an unlocked phone?
An unlocked phone is a device that is not tied to any carrier or plan. It lets you choose your phone first and your carrier second. Upon selecting a plan simply insert the carrier’s SIM card into the phone and you’re ready to go. If you decide you want to change carriers later or want to take an international trip, it’s as simple as replacing your existing SIM card with a new SIM card and activating your new plan.
