“We appreciate our customers’ patience while we work to resolve this as soon as possible,” the company said.
It comes as people on social media say they are struggling to access Vodafone customer service operators amid the ongoing issues affecting mobile data and broadband.
Many have also said they are having difficulty accessing the company’s website and app, which typically allow people to view the status of its network services.
Customers have also taken to social media to complain of “complete outages” in their area.
The issues appear to have begun for customers shortly after 15:00 BST.
Internet monitor Netblocks said in a post on X, external, live network data showed Vodafone was experiencing “a national outage” impacting both broadband and mobile data.
Some customers have expressed being doubly frustrated by not being able to access their Wi-Fi or mobile data.
“Sort it out soon please,” wrote one frustrated user.
