EU Roaming: O2 Remains the Only Major Network Offering It for Free
In a market where roaming fees have returned for many networks, O2 continues to stand out. It remains the only major UK mobile network that does not charge for EU roaming (up to 25GB) across 49 European destinations.
This means customers can call, text, and use data as they do at home, making O2 one of the strongest options for frequent travellers.
Learn more about O2 roaming policies on their official support page.
Should You Switch to O2 This Black Friday?
If you’re looking to upgrade your device or switch networks, O2’s 2025 Black Friday deals offer some of the largest handset savings on the market, alongside valuable extras like free EU roaming and Priority rewards.
With discounts ending 10 December, now is one of the best times of the year to lock in a flagship phone at a much lower cost.
