The CMA's inquiry group found in September that the merger could potentially raise prices for customers and harm mobile virtual network operators like Sky Mobile and Lyca. To address these concerns, the CMA is considering remedies that would allow the merger to proceed.

The proposed remedies include a commitment from Vodafone and Three to upgrade their network, particularly focusing on 5G rollout, over the next 8 years. Additionally, short-term protections are suggested to safeguard consumer interests during the initial phase of network integration and investment.

Stuart McIntosh, chair of the inquiry group, believes that with binding commitments and short-term protections, the merger could enhance competition in the UK mobile sector while safeguarding consumer and wholesale interests. The final decision is expected before the 7 December deadline, with feedback invited until 12 November.
