Does 5G work with Dual Sim?

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 the 5G network wherever it’s available on the O2 network.
