Three network customers across the United Kingdom faced a major mobile outage on June 25, 2025. The issue began in the early hours, and it lasted till evening. Many users were not able to make voice calls and use SMS services during that time. The problem started around 7:45 am of British Standard Time(BST) and the disruption of the ‘Three Network’ affected mobile virtual network operators like Smarty and iD Mobile, which rely on Three’s infrastructure. The British media has already declared this incident the second major network outage of the year.
The outage lasted around 12 hours and stayed active until 10 p.m. BST. Three previously assured that they were working hard to fix the problem and promised that the data services would work normally. Three Network hasn’t disclosed the reason behind the network outage, and they apologize for the inconvenience caused. The network outage was just weeks after Three Network UK finalized its £15 billion deal with Vodafone to form one of the largest telecommunications companies in the United Kingdom.
Three Network stated via X that they were aware of an issue affecting voice services and that they were working hard to fix it. They added that data services were working normally and requested that users accept their apologies for any inconvenience caused. Following an issue earlier that day, they reported that voice and SMS services were returning to near-normal levels while data services continued to work normally, and they were monitoring the network closely. They expressed their understanding of how disruptive the situation had been and sincerely apologised for the inconvenience caused that day.
Customers Demand Compensation for the Network Outage!
Following the network disruption, many users were angry and publicly criticized Three on social media for the inconvenience users faced. A customer asked whether customers would be compensated for the loss of services, and the other asked what they were getting for the disruption. Customers demanding compensation is understandable because a 12-hour network outage can create a lot of problems and inconvenience for a user, especially since we are living in the modern digital world where network coverage is as important as oxygen.

Simrat Sharma, a mobile expert at Uswitch, stated that the reported outages from Three this week would be incredibly frustrating for customers, and it was understandable that many would be considering compensation. She added that in extreme cases where repairs took much longer, individuals might be entitled to an additional refund or account credit. She advised that if anyone had experienced significant disruption from the outage, they should not hesitate to contact their provider to see if assistance could be offered.

Three Mobile Network Outage Compensation on a Case-by-Case Basis?
The Three Network has announced that the customers affected by the network outage reported on June 25 will be compensated on a case-by-case basis. Many customers were angry and confronted Three Network over potential compensation. The compensation will be paid on a case-by-case basis, and there is no guarantee you will get any. But if you are an affected individual, you have every right to ask for compensation. Here is how you can complain and win compensation from the Three Network.
To file a complaint and request compensation, customers can either use the ‘Live Chat’ feature on Three’s official website or dial 333 from their mobile. You must make sure that you have evidence when filing the complaint. If you don’t have any evidence that back your complaint, you might not receive the compensation, even if you are an affected individual. The users who have screenshots that explain the duration of the outage can submit those to prove their side and get adequate compensation.
Three has stated that individual compensation claims will be verified or assessed by their customer service team, and the customers need to contact customer support directly to initiate a claim. Ofcom, the telecommunications regulator in the UK, has an ‘automatic compensation scheme’ to address and compensate the disruptions affecting landline services and broadband connections, but the scheme is not applicable to mobile customers. So, an intervention by Ofcom and compensation procedures under the ‘automatic compensation scheme’ is a distant possibility.
