Our top plan
- Does 5G work with Dual Sim? Collapsed link
When using two connections in Dual Sim mode, 5G data isn't supported on either connection, so they’ll both use 4G. If you’re using a single sim only (or have only one sim active) and it’s a 5G one, then you can access 5G wherever it’s available on the O2 network.
