Can Apple phones have dual cards and dual standby?

Apple's mobile phone began to support dual card dual standby from 20 18, and iPhone XS Max was the first model to support dual card dual standby function.

Dual-card function is used by two nano-SIM cards. Dual-card function is supported by two nano-SIM cards in China, namely iPhone 1 1 Pro, iPhone1/pro max, iPhone XS Max and iPhone XR. You can use two phone numbers to make and receive calls and send and receive short messages.

GSM iPhone uses SIM card to identify mobile phones on GSM network. The SIM cards of the first generation iPhone, iPhone 3G and iPhone 3GS are all placed on the tray in the top slot of the mobile phone.

Both the SIM card opener and the word folder can open the SIM card tray. The SIM card opener is a simple liquid metal sheet attached to the iPhone.

By default, the home screen includes the following icons: information, calendar, photos, camera, stock, Safari browser, map (Gaode map or Apple map), weather, voice memo, notes, clock, calculator, settings, iTunes store and App Store. IOS4/4. 1 adds compass and FaceTime to iPhone 3GS and iPhone 4, respectively.

Users can also add or delete icons on the Dock of the home screen. Each layout of iPhone3G, iPhone 4 and iPhone 4S can accommodate 20 icons (including those on the Dock). Because the screen of iPhone5 is larger and can accommodate 24 icons, users can turn pages left and right, but the icons on the Dock will not move with it.

Users can move and delete instructions at any time by long pressing the third-party application, and can transfer some selected applications from iTunes. But Apple's default program can't be deleted. The update of 3.0 adds the system-wide search function Spotlight, which is located on the left side of the first home screen.
