-Always provides high availability for mobile data connectivity with industry leading secure private network options-

LONDON, UK. 17 FEBRUARY 2026 – Spitfire Network Services Ltd (Spitfire), the award-winning provider of voice, internet, IoT and wide area network connectivity services, today announced the launch of its dual-IMSI multi-network IoT data SIM, which will deliver secure, resilient and cost effective mobile connectivity for UK business.

Spitfire’s best in-class dual-IMSI multi-networking SIM solution provides very high availability for mobile data connectivity at all times, with industry leading secure private network options to protect against malicious actors. Designed for businesses that are looking to digitise their operations, boost efficiency or generate new revenue streams, Spitfire’s IoT data SIM solution is competitively priced with options starting from as little as £1 per month.

The SIM has two IMSI profiles. One IMSI on Spitfire’s Full MVNO with low latency direct layer 2 access to the Radio Access Network of a UK MNO with award winning coverage. A second IMSI on Cellhire’s overseas MVNO with roaming layer 2 access to all three other UK MNOs.  The default SIM configuration favours the Spitfire MVNO IMSI as the home (primary) network with seamless auto fail over to the Cellhire MVNO IMSI as alternative (secondary) network.

This configuration enables a number of benefits including lower cost and better performance, as well as low latency on the home network and increased resilience with the alternative network. This default SIM configuration can be changed over the air (OTA) to give priority to the Cellhire MVNO or modify other settings as appropriate. The SIM and device use the same APN and IP address for both IMSIs, which means a ‘set and forget’ configuration with no requirement to update network settings on failover. A range of secure options are available that take advantage of Spitfire’s One Network^® and SUN^® .

Harry Bowlby, Managing Director, Spitfire Network Services Ltd said: “We’re very excited to bring our unique dual-IMSI one IP address Multi Network IoT data SIM solution to market after spending many months ensuring we have a product that delivers first class mobile connectivity that is secure and robust. The use cases that IoT enables are endless and the benefits it can offer businesses can be significant. However, without the right level of connectivity the potential of IoT can be stunted – and that is exactly the challenge our solution addresses.”

Spitfire’s IoT data SIM is competitively priced, with flexible options (Pay As You Go, Bundle and Pool options) for any data usage or number of SIMs. Prices start from £1 per month.

IoT customers of Spitfire have access to an Online customer portal for management of SIM estate and other services, and dedicated account management from an IoT specialist.
