## Description

MDD Sim Gateway is a self-hosted multi-SIM communication gateway that lets you use physical SIM cards and eSIMs for VoWiFi calling, SMS/MMS, and 4G cellular data on your own hardware. It supports cellular modems and USB PC/SC readers, handles EAP-AKA and IMS-AKA authentication entirely on the SIM (never extracting Ki/OP/OPc), and routes each SIM's ePDG traffic through a chosen country exit via independent TUN interfaces (host install) or SOCKS5 (container deploy). The web console provides a browser-based softphone, SMS/MMS messaging, call logs, missed-call notifications, per-line voicemail, balance/keep-alive monitoring, and automatic updates. It integrates with Telegram, PushPlus, Lark/Feishu, and generic webhooks for notifications. Two deployment modes are documented: a host-assisted install on Debian/Ubuntu/Armbian ARM64 that sets up systemd services and Docker engines, and a fully containerized Docker Compose deployment for any amd64/arm64 Linux including Synology NAS. The project is licensed GPL-3.0-only and builds on upstream components including pagecat/vowifi_gateway, sysmocom Asterisk, sing-box, and lpac.
