Ofcom Investigates BT and Three Over 999 Call Failures

Ofcom has opened formal investigations into BT and Three following separate UK-wide mobile network failures this summer that left some customers unable to connect 999 emergency calls.

Two Major Outages

The investigations centre on two major outages, one affecting Three customers in June and another impacting BT and EE customers in July, both of which disrupted basic voice services across large parts of the country. Ofcom said it is examining whether the companies took sufficient steps to prevent the incidents and to protect access to emergency services, which are treated as a critical national function under UK telecoms regulation.
