南下美国手机roaming省钱办法

通常人们南下美国的话都把手机关掉或者飞行模式。开手机的话也不敢用上网打电话，之前有人就收到一个$22,000的账单。但是这样的话有重要信息的话，就没办法接收了。或者想用微信，skype也不行了。
这里我想我可以给大家一些意见吧
首先我会推荐下T-Mobile的Prepaid的套餐

Great for email, Facebook, web surfing, GPS navigation, downloading apps/music/games, and more.

Unlimited Talk
Unlimited Text
Unlimited Web – First 200MB at up to 4G speeds

现在的Roam as home，对于短时间去美国的，还是很方便的。

另外还有一些Prepaid Plan 其实也是值得推荐的。但是很麻烦的是现在不允许快递Sim卡。所以3HK，变成比较推荐的方案，如果你的手机支持eSIM卡.下面的信息来源是RFD

Was searching for a ESIM for my UK travels and this caught my eye. Having this might be cheaper than getting a data SIM locally.

20GB available for a $10 more. Downside is I believe the internet traffic is routed via HK so might not be the quickest. Uses the Rogers network in Canada.

[Plans]
$138 HKD/$22 CAD – 30 Days – 10GB
$198 HKD/$32 CAD – 30 Days – 20GB
$298 HKD/$44 CAD – 365 Days – 30GB + 5 GB of Social Data

[Notes]

• All plans are unlimited data, after the usage is exceeded speed are slowed to 128kbps
• Social Media Data is only available to the use of mobile apps (Facebook, Instagram, WhatsApp, LINE & WeChat)
• HK IP Address is given when using the mobile data

[What is a eSIM?]
The eSIM works the same way as a traditional SIM card, but you don’t need a physical SIM card to use it. It is actually pre-installed in the device and you can activate it by installing an “eSIM profile” on it.
