Frequently Asked Questions
What is the Vodafone-Three supernetwork?
Vodafone and Three are merging to create the UK's largest mobile network by spectrum holdings and mast sites. The combined supernetwork will deliver improved 5G coverage, greater capacity, and faster speeds for business and consumer customers. Existing contracts on both networks will be honoured.
Should I choose Vodafone or Three before the merger completes?
Both networks will benefit from the merger. If you want the cheapest unlimited data right now, Three is cheaper. If you want better international roaming and dedicated account management, Vodafone is stronger. Both sets of customers will benefit from the combined supernetwork infrastructure.
Is Three or Vodafone cheaper for business unlimited data?
Three is cheaper. Three offers the lowest-priced unlimited data business plans in the UK. Vodafone's unlimited plans are available but at a higher price point, reflecting its broader international roaming and dedicated account management services.
Which network has better 5G — Vodafone or Three?
Three has strong 5G in major UK cities and holds more 5G spectrum than Vodafone individually. Vodafone's 5G coverage is growing but trails Three in city centres. Post-merger, the combined network will have more spectrum and mast sites than any competitor, delivering the best 5G experience in the UK.
Will my existing Vodafone or Three business contract change after the merger?
No. Existing contracts on both Vodafone and Three will be honoured in full. You will continue on your current terms until your contract ends. The merger will bring infrastructure improvements that should benefit all existing customers through better coverage and speeds.
