VOXI esim拉起WifiCalling的经历

TLDR：使用hideck成功拉起VOXI esim卡wifi calling实现发短信保号

AI时代，越来越多的互联网服务注册要求手机号认证，众所周知一些网站不对国内服务，因此海外sim卡已经成为IT基础设施之一了。

之前购买了VOXI的esim搭配eUICC白卡修改默认apn后能够成功接收短信，但是由于无法拉起WifiCalling无法拨打电话或者发送短信，产生不了费用导致无法保号。充完5英镑后，想着180天还有很久便搁置下了。

最近在思考openwrt+sms-tools的替代方案，sms-tools删除短信时经常会有bug，以及没有API或者消息推送用来获取短信内容。正当准备让AI写一个USB LTE MODEM管理软件时，发现有VoHive这种现成的项目，不过江湖再见了，于是又找到了HiDeck和这篇文章，试了下果然成功了。

弯路

最初按照网上视频教程里的过程操作，让ios15的iphone7关闭飞行模式打开Wifi，并且获得了英国IP后，尝试打开无线局域网通话，能看到隧道有网络流量产生，但是一直没有获得WifiCall标志。

因为iphone不方便获取相关日志，没法知道失败的原因，有说法是要用英国家宽的IP，但手头的主机都是数据中心的IP。

事实证明并不需要家宽IP也可以拉起WifiCalling，卡策略-通话方式选择Wifi calling之后，会自动开启飞行模式，不一会就发现VoWifi已连接。

查看日志可以观察IMS注册过程

保号

连上VoWifi后就可以发送短信来保号了，尝试了给+86手机号发短信成功扣费了，虽然实际没有收到短信。或许是运营商拦截了境外短信呢。

如果想要验证发送短信功能是否正常，可以免费发送短信INFO到85075，自动收到短信回复的话就是正常了。

一些猜测

iphone上默认apn是wap.vodafone.co.uk，这时候连国内运营商的漫游信号都收不到，修改成payg.talkmobile.co.uk之后就能成功驻网漫游接收短信了。但是Hideck上，使用自动apn，也能直接获得中国移动的漫游信号，查询apn发现当前使用的apn是3gnet和ims。

>AT+CGCONTRDP

+CGCONTRDP: 1,5,3gnet,10.22.153.209,,,
+CGCONTRDP: 2,6,ims,10.105.178.69,,,,10.127.192.83,10.127.67.198

或许在国内只要用3gnet默认的apn配置就可以了吧，iphone上获取了sim卡的vodafone apn配置反而不行。

另外通过wificalling注册完ims之后，之后通话方式改成蜂窝数据也能保持wifi calling连接。不过这时候发现是接入了中国移动的信号漫游的，听说英国运营商只允许短期旅行漫游使用，为了防止封号还是开启飞行模式使用wifi calling来收发短信吧。或许有用呢。
