2G CSD Sim cards

Mid and West Wales Fire and Rescue Authority are publishing this Preliminary Market Engagement Notice to notify suppliers of our intentions to procure 60 replacement 2G CSD Sim Cards. Details of the new contract will be contained in the tender documentation, with the tender advertised in May 2026 following the engagement event. The aim of this procurement is to address recently identified issues with our backup emergency mobilising system, which relies on Circuit Switched Data (CSD) over the 2G mobile network. We have identified faults with our current CSD compatible SIM cards and now need to procure replacement SIMs that will continue to support CSD for at least the next two years. This system provides essential backup capability to ensure that crews are reliably and effectively mobilised to incidents. The desired contract period would be for a two-year period, with possible extensions depending on whether the infrastructure is still available to support.
