The iPhone 16 Plus is eSIM compatible and offers dual SIM functionality. With the iPhone 16 Plus, you can use either two eSIMs or a combination of one physical SIM card and one eSIM simultaneously. It is not possible to use two physical SIM cards in parallel. Setting up your BuddySIM eSIM is easy via QR code scan or using the Apple Universal Link from iOS 17.4 onwards. The range of available functions may vary depending on the country where the iPhone model was purchased. iPhone 16 models purchased in Germany allow the simultaneous use of up to two eSIMs on the iPhone 16 Plus. iPhone 16 Plus models purchased in China, Hong Kong, and Macao are not eSIM capable.
