YX-MoIP 16-Port Multi-SIM SMS Gateway – High-Capacity, Intelligent SMS Routing

Designed for telecom carriers, SMS aggregators, and enterprise communication platforms, the YX-MoIP 16-port gateway combines advanced embedded technology with intelligent SIM management. It enables cost-effective SMS delivery by dynamically routing traffic across multiple SIM cards, reducing operational costs while maximizing throughput.

Multi-Port, Multi-SIM Architecture
Each of the 16 physical ports supports multiple SIM cards, with total SIM capacity options of 16, 64, 128, 256, or 512 cards. Only one SIM per port is active at a time, while the remaining SIMs serve as backups. The gateway automatically switches SIMs based on predefined rules—such as consecutive failures, total SMS count, signal quality, or time-based scheduling—ensuring high availability and uninterrupted service.

Flexible Network Compatibility
Choose between 2G GSM (M26 module) or 4G LTE (EC25/EG25-G module) to match your regional network requirements. The EG25-G global version supports full-frequency bands, making it suitable for worldwide deployment. Region-specific models are also available for optimized performance in North America, Europe, Asia-Pacific, and Latin America.

Intelligent SIM Rotation & Automation
The gateway includes a robust SIM switching engine that supports:

• Consecutive failure count checks

• Total sent/received SMS thresholds

• Online time scheduling

• USSD balance queries

• Signal strength monitoring

• Port inter-call simulation

These features help prevent SIM blocking and maintain high SMS success rates across your infrastructure.

Advanced Connectivity & Integration

• Network Protocols: Static IP, DHCP, PPPoE, VPN (PPTP/OpenVPN)

• SMS Protocols: SMPP 3.4, HTTP API (GET/POST), EIMS, SMS-to-HTTP forwarding

• Remote Management: ERMS/ETMS server support, web GUI, SSH, SNMP

• SMS Features: Scheduled SMS, SMS forwarding, MMS support, inbound SMS filtering, USSD auto-query

Built for Scalability & Reliability
With hardware support for up to 512 SIM cards and software-level automation, the YX-MoIP 16-port series is built for high-volume SMS operations. Its embedded Linux core ensures stable performance, while configuration backup, system logs, and remote update capabilities simplify maintenance.

Ordering & Customization

Global shipping options include DHL, UPS, FedEx, and dedicated lines with tax-inclusive delivery available for select countries.
