看过推文后来我有去查了一下，顺便补充一下

新闻这篇讲的很死，
那国买的就只能用在该国的电信且不支援漫游（且是硬件上的无解）
但他举的例子又是美国和德国两个频段本来就不相容的国家
？？？
根据官网applewatch支援频段机种只有分为三种

而台湾目前的LTE频段是700 900 1800 2600 也就是跟第二种日、英、德等的频段应该是可以兼容的
但是点日本的购买官网又有下面的附注

大意是必须和iphone同电信商且对应的电信商为以下三个
所以也有锁电信商可能存在（但也不排除是避免繁杂所以只列出该国电信）
也就是日版的之后在台湾也是有可能能够支援的
（虽然我觉得等到series 5应该都出来了……）
而且比较高阶的款式都是LTE版才有…
所以只能等发售后再看看了
