Spitfire’s Dual IMSI Multi-Network SIM uses dual IMSI profiles, unlike other SIM providers that typically use only one. The first IMSI connects to our home network, while the second enables seamless failover to all other major UK MNO networks in the unlikely event of a loss of connection to the home network.

So why is this better?

Key Benefits of Prioritising the Home Network

• Reduced Cost: Decreases data costs by steering traffic to the home network when the signal is strong, benefitting from favourable rates by doing so
• Lower Latency: Through the same steering mechanism, the SIM will always ensure the home network is used where possible, to benefit from the lower latency available via this network
• Data Stays Within the UK: When the home network is used (on IMSI 1) the data will stay within the UK, as opposed to other single IMSI Multi-Network SIMs on the market which route ALL your traffic via non-UK based mobile networks

Key Benefits of the Multi-Network IMSI Acting as a Backup

• Enhanced Resiliency: If the home network signal is weak, the SIM uses a secondary IMSI to seamlessly connect to another network with a suitably strong signal to maintain a continuous service
• Maximum Coverage: Access to all UK MNO networks through this Dual-IMSI approach ensures your IoT devices stay connected, even in areas with limited coverage
• Automatic Reconnection: Once the home network signal is restored, the SIM redirects to this route to once again optimise for cost and latency
• Permanent Roaming Agreements: We have permanent roaming agreements in place to ensure the SIM is never kicked off any of the available networks, a common issue with other Multi-Network SIMs

This Dual-IMSI design combines the benefits of low-cost, low-latency home network access with the resilient, wide-reaching connectivity of a Multi-Network SIM, bringing you the best of both worlds!

Yes! Spitfire’s layer 2 interconnect with a French MVNO network provides offshore UK roaming access to all four MNOs, without use of the public internet.

As all data remains on-net with Spitfire, the IP address configuration remains the same, the APN remains the same, and your data does not traverse the public internet when using the secondary IMSI profile.

IoT devices, whilst incredibly beneficial, are also potential entry points for cyberattacks. They are often seen as easy targets as any device is ultimately only as secure as the network to which it is connected and operates over, with cyber-security threats ever increasing:

• IoT malware attacks up 107% year-on-year
• 50% of all UK businesses experienced a cyber breach in last 12 months
• 526 new malware variants detected per day

Spitfire’s One Network^® offers a secure IoT solution by ensuring end-to-end connectivity while completely isolating your devices and data from the public internet. This approach enhances security and reduces complexity by bypassing traditional internet routes. The solution supports multiple connectivity options, including mobile, fixed line, or cloud, with a straightforward and cost-effective setup.

For IoT solutions that require some level of internet access or integration with existing systems, One Network^® offers a secure, enterprise-grade entry point via a hosted Firewall as a Service (FWaaS) solution. Using Fortinet FortiGate firewalls, FWaaS provides advanced security features such as Geoblocking, and remote access options while maintaining network integrity – we call this Spitfire Unified Network^® (SUN^®).

Key Security Benefits of One Network^®

• Complete isolation from the public internet
• Devices invisible and unreachable to hackers
• Enterprise-grade security options for internet access, where required
• Reduced and simplified configuration requirements

Dual IMSI Multi-Network SIMs are available from less than £1.00 per month, with competitive per MB rates offering unmatched market value.

We offer a range of pricing models, including Pay Per MB, data bundles, and pooled data to fit any business need.

Although we cannot offer international roaming at this time, we will soon enable our SIMs to securely transmit data in more than 191 countries, utilising 430 operator relationships worldwide. Watch this space!
