Yesterday Apple released iOS 14.5 alongside iPadOS 14.5 and watchOS 7.4 to its users worldwide. One more under the radar feature with the new update for iPhone 12 series users is the ability to have 5G connectivity in Dual SIM mode.
Dual SIM 5G confirmation from Apple
Prior to the update, you would be restricted to 4G LTE when using two SIM cards simultaneously regardless if they were 5G ready. Now, you can only have one line on 5G connectivity and it will only be used for data according to the official changelog released by Apple.
Smart Data Mode can now switch to 4G LTE connectivity when you aren’t using your iPhone to help extend battery life.
