5G+ FAQs
5G+ is our name for 5G Standalone. It’s the latest version of 5G technology and runs independently, rather than relying on older network systems.
5G+ is designed to be more reliable and consistent, particularly in busy areas. It helps keep your connection more stable and responsive, so everyday apps and services work more smoothly.
