The UK regulator Ofcom has launched two probes investigating mobile operators EE (BT) and Three over their summer network outages.
Both networks suffered outages resulting disruptions this past summer across the country. “BT has notified Ofcom of a software issue that resulted in a UK-wide disruption to mobile call services interconnecting to and from the EE network on 24 and 25 July 2025.” said Ofcom. “This resulted in BT and EE customers being unable to make or receive mobile calls to other networks and emergency services.”
While BT has identified a software issue it is not clear yet whether the Three outages were related. Reports at the time alluded to Three customers potentially facing problems if they were unable to contact EE customers, and Ofcom said the Three outage which took place on 25 June 2025 included contacting emergency services.
