The sibling comments here are also correct of course but keep in mind that 5G, excluding stuff like mmWave, does not prescribe any particular frequency band to use and can work on just about any. Regulators will find some slice of free frequency space somewhere between roughly 1 GHz to 5 GHz and auction it off and then carriers and device manufacturers will make 5G run in that band. The iPhone 13 for example can use literally 30 different 5G bands on the US models.
