BT Group has more than 30 million customers in the UK and made £20.4bn revenue in the last financial year.

Thousands of customers using EE and BT services across the UK faced widespread disruptions recently, with many unable to make or receive calls on both mobile phones and landlines.
According to Downdetector — a popular outage tracking website that collects user reports — over 2,500 EE customers experienced network issues around 2 PM BST. Reports also indicated similar problems affecting BT customers, as the two networks are linked.
Some users even faced difficulties trying to make emergency 999 calls, though government officials confirmed these issues have since been resolved.
A BT spokesperson acknowledged the problem, apologizing for the inconvenience and stating, “We are urgently working to resolve the issue affecting our services and will provide updates as soon as possible.”
Meanwhile, other major UK mobile networks like Vodafone and Three assured the public they were not facing any network problems during this outage.BT mobile and landline issues
