Three outage leaves thousands unable to make calls

The firm said people were still able to use mobile data services and make 999 calls during the outage. Three's support team has been telling customers that it does not "have a timeframe" for a fix, but that the firm is "working hard to resolve this as soon as possible". Three has around 10.5m customers across the UK, according to its website, but it is unclear how many of them are affected by the outages. Many people on social media have shared their frustration at the outage and described the disruption they said it had caused them. One person claimed they had "missed a medical appointment" as a result of being unable to receive calls, while another said the issues had left their daughter "stranded".
