   - **`DMenu` (`dmenu.so` / `dmenu` / `xdmenu`)**: zero-lag (`< 2 ms` popup/close) resident `240x320` full-screen 10-line vertical menu (`240x296` flush below the 24px top bar) with a `#383838` search bar, `#005577` prompt badge, `XIM` `fcitx5-t9` text input, in-place `< 0.5 ms` native Sxmo submenu transitions (`Sys`, `Apps`, `Scripts`, `Modem`, `Config`, `Power`, `Audio`, `Notifications`, `WM`, `Timezone`, `Games`, `St`, `Nano`), and a `/tmp/dwm_plugin_dmenu.sock` client interface serving all `/usr/bin/dmenu` and `sxmo_dmenu.sh` pipes instantaneously.
   - **`XDrawer` (`xdrawer.so` / `xdrawer`)**: global phone controls overlay invoked from anywhere by pressing **both softkeys simultaneously**, providing instant sliders and toggles for speaker volume, earpiece volume, ringer mode (`Ring+Vib` / `Vibrate` / `Silent` / `DND`), flashlight, sound mute, microphone mute, screen brightness, and keypad backlight.
-  - **`Dialer` (`dialer.so` / `xdialer`)**: opens automatically from the idle desktop when pressing any **`0`–`9`, `*`, or `#` key** (inserting that character immediately), with live T9/number contact filtering, hold-`0` for `+`, and single-press **Call** dialing.
+  - **`Dialer` (`dialer.so` / `xdialer`)**: opens automatically from the idle desktop when pressing any **`0`–`9`, `*`, or `#` key** (inserting that character immediately), with live T9/number contact filtering, hold-`0` for `+`, single-press **Call** dialing, direct USSD code execution (`*100#`, etc.) with interactive session reply modal, and instant **`*#06#`** Dual-SIM IMEI (`IMEI 1` & `IMEI 2`) display.

   - **`Call Screen` (`callscreen.so` / `xcallscreen`)**: dedicated incoming, outgoing, and in-call screen integrated with Sxmo's `ModemManager` call lifecycle (`sxmo_modem.sh`, `sxmo_modemcall.sh`, `sxmo_modemdial.sh`), displaying resolved caller name and phone number, accepting/rejecting incoming calls via physical **Call (green)** and **End (red)** buttons (plus `*`/`0` ringtone silence), live `MM:SS` call timer, microphone mute/unmute (`1`/`*`), live call recording to `~/Recordings/call_<caller>_<timestamp>.wav` (`2`/`#`), earpiece/speaker audio routing (`3`), volume control (`Left`/`Right`), and DTMF tone keypad mode (`0` / `Left softkey`).
   - **`Contacts` (`contacts.so` / `xcontacts`)**: full-featured phonebook application opened from the idle desktop via the **Right softkey (`Names`)** or from the Sxmo menu, integrated with `~/.config/sxmo/contacts.tsv` (live T9/number search, call/SMS/dialer actions, built-in contact editor with keypad multi-tap name entry and recent-caller number picker, and contact deletion).
