# Client Phone Usage Guide
The client phone addon provides the in-game phone UI for contacts, SMS
messages, email, and local utility apps such as notes, calendar events, world
clocks, and alarms.
## Open Phone UI
```sqf
call forge_client_phone_fnc_openUI;
```
The phone UI creates `RscPhone`, loads `ui/_site/index.html`, and routes
browser alerts through `forge_client_phone_fnc_handleUIEvents`.
## State Ownership
Contacts, messages, and emails are server-owned and requested through the
server phone addon.
Local utility app state is stored in `profileNamespace`:
- notes
- calendar events
- world clocks
- alarms
- theme/preferences
## Phone Class
`forge_client_phone_fnc_initClass` creates `GVAR(PhoneClass)`.
The phone class currently owns local notes, events, and settings helpers.
Contacts, messages, and emails continue to use server-backed request/response
events.

## Usage Rules
- Send contact, message, and email mutations to the server phone addon.
- Keep local-only utility apps in `profileNamespace` until they are migrated to
server-backed storage.
- Do not treat local phone utility state as shared multiplayer state.
- Validate required UID, phone, email, subject, and message fields before
sending server requests.
