UK degraded connectivity on G1 profile (ICCID prefix 8944*)

Starting October 1st, 2025, O2 UK began decommissioning its 2G and 3G networks across the UK, with full shutdown expected by the end of the year. As a result, some devices using these legacy networks are transitioning to other available carriers. We've observed that on our G1 profile (ICCID prefix 8944*), certain devices are having trouble transitioning to other available carriers and using other RATs like Cat-M where supported by the devices. Our team is actively investigating this with our upstream connectivity partners to identify and resolve the root cause. We'll continue to share updates as we learn more.
