Is there anyway or luci-app could let me see sms in luci?
You can see it in the default firmware. I search from Google, it seems there has such a Luci application, https://github.com/lzto/luci-app-smstool, but you need to build it by yourself.
But, could you give me some materials about how to build it?
I am a newcomer.
I didn’t use luci. But i assume this is complicated. If you can just try your mifi as it has a built in modem and support sending sms right away.
