The outage lasted for some 24 hours and led to millions of customers being unable to access voice or data services. Many subsequently threatened to leave the firm and move to a rival network operator unless some form of compensation was provided.
O2 has now revealed its plans to make up for the outage to customers, which include a 10 per cent price discount on July bills for contract customers, which will be applied in September. Pay and go customers will receive 10 per cent extra on their first top-up in September.
The compensation will only be available for those that were affected, with O2 explaining it has been able to identify the handsets that were unable to connect to its network.
However, all customers, irrespective of whether or not they were affected, will be eligible for a £10 O2 Priority Moments voucher to spend in store with firm.
Consumers and firms with fewer than 10 connections will receive more information from the firm via text message. Those with over 10 connections will be contacted by account managers or channel partners offering more information.
The scope of the compensation O2 is offering underlines how serious it is taking the outage, and mirrors similar steps taken by Research in Motion to try and appease BlackBerry customers after the firm's network went down for almost three days in late 2011.
