Ok, it is done.  
Writing down my path for the sake of future noobs like me. I couldn’t find this info in a single place.

For `luci-app-watchcat` (or anything needed from official OpenWRT repos):

1. Start from the OpenWRT [Package Table](https://openwrt.org/packages/table/start). For the Name ‘watchcat’ It shows two packages in two Categories (not counting the language pack): `luci-app-watchcat` and `watchcat`. Don’t worry about dependencies for now.
2. For each Category copy its link and make it a line in _ADMIN PANEL_ → _MORE SETTINGS_ → _Advanced_ → _luci_ → _System_ → _Software_ → _Cofigure opkg_ → _opkg/customfeeds.conf_. In this case the lines are:

```auto
src/gz luci_app https://openwrt.org/packages/index/luci---applications
src/gz openwrt_utils https://openwrt.org/packages/index/utilities

```

(the repo names after `src/gz` are whatever, then the copied links follow). Then hit _Update lists_ and install the needed packages.  
In other words, the Category to which a package is assigned can be treated as a narrow-scope repository. So next time I’m going to need some ‘luci-application’ or ‘utility’ from OpenWRT, it will be waiting for me in Luci (or _ADMIN PANEL_ → _APPLICATIONS_ → _Plug-ins_, with _Filter_ → _All_).

With the `luci-app-sms-tool` it’s more tricky as it’s not a part of OpenWRT:

1. For sending SMS messages (and USSD, and AT, etc.) from the stick-modem Huawei E3372s, start with the [forum post](https://forum.openwrt.org/t/e3372-ussd-sim-menu-etc/87785/5).
2. There are two packages to be installed. It’s best to just download them as _.ipk_ files for manual upload to Luci, from [here](https://github.com/4IceG/luci-app-sms-tool/releases) (`luci-app-sms-tool-...`) and [here](https://dl.eko.one.pl/openwrt-19.07/packages/mipsel_24kc/base) (`sms-tools-...`). In the latter link, one must make sure that `/mipsel_24kc/` is the correct Package architecture for the router ([Techdata page](https://openwrt.org/toh/hwdata/gl.inet/gl.inet_gl-mt300n_v2)). That’s the tricky part.

I tried to use the _Download and install package_ box in _Luci_ → _System_ → _Software_, but it ‘failed to extract the control file’, so had to upload from disk.

I think the watchcat installation froze opkg in the end, but refreshing the page was enough to break the loop. All fixed.

The tool ‘Watchcat’ resides in the new top-menu ‘Services’.  
The tool ‘SMS Messages’ resides in the new top-menu ‘Modem’.  
To see them, just refresh the page.

Now, the E3372s-153 modem can be conveniently (ab)used with Mango.
