Can I get compensation for a Three outage?
Three's pay monthly terms (version effective 12 October 2026) say that if you have continuous or regularly recurring disruption, you may be entitled to a price reduction based on the period, as a partial or full credit or a refund of your Monthly Charge. You must report the disruption; Three measures it against your typical usage history, and an alternative such as WiFi Calling must be unavailable to you. Source
When will it be fixed?
Only Three knows. If Three lists the problem on its official outage page, that is where an estimated fix time appears. We cannot see Three's network: our live page shows whether reports from other customers are still coming in, and a drop in reports usually means service is coming back.
Tell others it is not just them
A report on our page does not reach Three, but it shows other Three customers nearby what is happening. Reports are anonymous.
