What being on O2 means

An MVNO buys wholesale access to a main network and resells it under its own brand, usually much cheaper. The trade-offs vary by network: some get every feature the host offers, others miss things like eSIM, visual voicemail or 5G Standalone, and traffic can be deprioritised at busy times. The table above shows the essentials — click any network for the full feature breakdown.
