Frequently Asked Questions

FusionGate is a software-based GSM termination and VoIP gateway solution that transforms Samsung Android smartphones into professional GSM gateways. It allows you to route VoIP calls through GSM networks using the device's native SIM cards, providing a cost-effective alternative to traditional SIM box hardware.

Traditional SIM box hardware costs $2,000–$5,000 per unit, requires rack mounting, and is easily detected by carriers. FusionGate uses regular Android smartphones ($99 license + ~$150 phone), is mobile and portable, and provides natural stealth behavior since phones appear as regular smartphones to network operators.

FusionGate is certified for Samsung Galaxy devices:

• Samsung Galaxy A15 (Android 14, 15)
• Samsung Galaxy A16 (Android 14, 15)
• Samsung Galaxy A53 (Android 13, 14)
• Samsung Galaxy A54 (Android 13, 14, 15)

We continuously expand device support. Contact us for information on other models.

No. FusionGate licenses are one-time purchases with lifetime entitlements. There are no monthly or annual fees. You pay once and use the license forever on that device.

Each license is tied to the device's Android-ID and device fingerprint. This creates a unique identifier for each phone, ensuring licenses cannot be copied or shared between devices.

Yes. You can request license reassignment within your purchased capacity at any time. Contact our support team with your current device details and the new device's Android-ID to process the transfer.

If your device breaks or needs to be replaced, you can transfer the license to a new device. Contact support with proof of the original device (license key, device fingerprint) to request reassignment.

Each license covers one device, which can use up to 2 SIM cards (dual-SIM). Both SIM slots are included in a single license — no additional fees per SIM.

Yes! We offer up to 3 free lifetime licenses for testing. Contact us to apply for free test licenses.

FusionGate uses the device's native GSM audio path, so call quality is indistinguishable from a regular mobile phone call. VoIP calls exit the device as native 3G/4G/5G GSM calls with full audio quality.

FusionGate supports standard VoIP codecs including:

• G.711 μ-law and A-law
• G.729
• G.723.1
• RFC 2833 DTMF

Each device can handle one call per SIM slot. With dual-SIM devices, you can have up to 2 concurrent calls per phone. For higher capacity, deploy multiple devices.

Yes, FusionGate supports WireGuard VPN for enhanced security and to bypass IP filtering in certain regions. VPN configuration is optional but recommended for hostile environments.

FusionGate includes several features to appear as a regular phone to carriers:

• Human-like call pacing: Random delays between calls
• SIM rotation: Automatic switching between SIMs
• Variable call duration: Avoids predictable patterns
• Rest periods: SIMs rest after configurable usage
• Natural device behavior: Regular Android phone, not identifiable as gateway hardware

FusionGate includes self-healing automation:

• Auto-reconnect for SIP registration
• Automatic SIM recovery after network issues
• Watchdog service to restart unresponsive components
• Configurable scheduled reboots

Complete setup (rooting + installation + configuration) typically takes 30-60 minutes per device. Experienced operators can do it faster with practice.
