Fixed IP Multi-Carrier SIMs
Reliable Global Connectivity with Static IP for IoT, M2M & Remote Devices
Fidelitel Fixed IP SIMs provide secure, always-reachable connectivity for IoT and M2M devices by assigning a static public IPv4 address to each SIM. This allows direct inbound access to devices from anywhere in the world, without VPN workarounds, reverse tunnels, or unreliable relay services.
Built for enterprises, system integrators, and industrial deployments, Fidelitel Fixed IP SIMs eliminate the limitations of carrier NAT and deliver predictable, secure remote access across global cellular networks.
What Is a Fixed IP Multi-Carrier SIM?
A Fixed IP Multi-Carrier SIM is a cellular SIM or eSIM designed for professional IoT and M2M deployments that require reliable global connectivity and direct remote access.
It combines three critical capabilities in one solution:
- Multi-Carrier Connectivity ā Automatically connects to the strongest available mobile network from hundreds of carriers worldwide, ensuring optimal coverage and uptime.
- Static Public IP Address ā Assigns a fixed IPv4 address that never changes, allowing devices to be reached directly at the same address every time they connect.
Global Operation ā Works across countries and regions without manual carrier switching, roaming complexity, or multiple telecom contracts.
Most mobile operators place IoT devices behind carrier-grade NAT (Network Address Translation). Workarounds such as VPN hubs, tunnels, or relay services increase cost, complexity, and latency. While this allows outbound traffic to the cloud, it blocks inbound connections, making it impossible to directly access devices for:
- Remote administration
- Diagnostics and troubleshooting
- Live data access or video streaming
- Industrial control and monitoring
- Automatic Network Connection: When powered on, your device connects to the strongest available cellular network in its location using a Fidelitel SIM.
- Static Public IP Assignment: Fidelitel assigns a fixed public IPv4 address to the SIM. This address remains the same across reboots, power cycles, roaming, and network changes.
- Carrier NAT Bypassed: By using a fixed IP, carrier-grade NAT is eliminated, allowing direct inbound connectivity to the device.
- Secure, Direct Communication: Devices can securely send and receive data using stable addressing, enabling remote access, administration, diagnostics, streaming, and control.
- Centralized Global Management: Administrators monitor, manage, and configure connectivity through the Fidelitel platform or API, scaling easily from a single device to global fleets.
Carrier NAT is acceptable for basic outbound telemetry, but it fails for real-world operational control.
- Devices use private, shared IP addresses
- Inbound traffic is blocked by the mobile network
- IP addresses change after reboots or roaming
- Firewall allow lists break
- Direct access to HTTP, SSH, RTSP, Modbus TCP, or SNMP is impossible
- VPN hubs, reverse tunnels, or relay services add cost, latency, and failure points
A Fixed IP SIM bypasses carrier NAT by assigning a static public IPv4 address directly to the SIM. Your devices are always reachable at a known, predictable address, no matter where they are deployed. This is the cleanest and most reliable way to enable inbound IoT connectivity.
- Each SIM receives a static public IPv4
- The IP remains consistent across reboots and roaming
- Devices are reachable directly at IP + port
- Only required ports are exposed
- Inbound traffic can be restricted to trusted source IPs
- Standard encryption (TLS, SSH, VPN) can be used
- No relay services, no tunnels, no hacks
With Fidelitel Fixed IP SIMs, your devices are always accessible at the same address. Whether your device is deployed in a city, a remote field site, or crossing borders, its address stays the same.
- Reach devices instantly for maintenance or diagnostics
- Initiate inbound connections without device-side changes
- Maintain stable firewall rules and allow lists
- Avoid IP churn caused by roaming or reconnection
A static public IP does not mean open exposure. Fidelitel Fixed IP SIMs are designed with enterprise-grade security controls. You maintain full control over how and when devices can be accessed:
- Open only the ports you need
- Restrict inbound traffic to trusted source IPs
- Use TLS, HTTPS, SSH, or encrypted industrial protocols
- Combine with private APN or VPN if required
- Update access rules centrally without touching the device
Fidelitel Fixed IP SIMs allow you to connect directly to device services at a known address, no relays, no middle layers, just direct communication including:
- RTSP for live video streams
- HTTP / HTTPS admin interfaces
- SSH for remote maintenance
- SNMP for monitoring
- Modbus/TCP and industrial protocols
- Custom TCP/UDP services
Fidelitel Fixed IP SIMs can be combined with Multi-CarrierĀ connectivity, allowing devices to automatically connect to the strongest available carrier while retaining the same static IP. Ideal for mission-critical deployments that cannot afford connectivity loss.
This delivers:
- Higher uptime
- Better coverage in challenging locations
- Seamless roaming across regions
- Consistent addressing across networks
