They sent me an email in October 2025 that the price would be increased in April 2026, but they did the increase from November 2025 without any notification, in January discovered that O2 increase from November and for more money that they notified in the email in October, immediately I cancelled the contract they gave me the date of last day service but they tried to charge me again in February, I called them to explain that our contract had expired, they gave me apologies but the worse from O2 was that damage my credit report because I didn't want to pay after that our contract had expired, really I don't recommend O2 my experience was terrible now my credit score was damaged for fake report from O2

Amazing experience-highly recommend the store
We went in to get a first phone for my son and were seen by Emma in the Castle Lane store, Belfast. She was absolutely amazing with him. She took asked him questions about how he was going to use it and then recommended a phone and took him through the features. She was so personable, knowledgeable and friendly- she made the experience great instead of the stressed out mess I was anticipating.
