Scott Brown / Android AuthorityTL;DRGoogle is testing a new option to choose your preferred calling SIM within the Phone app.This prevents users from having to choose the preferred SIM before every call.Users will still have the option, even if they choose a default SIM in the phone’s Settings.Dual-SIM Android phones are now fairly common. Even devices that don’t have two physical SIM slots, such as Google Pixel phones, let users use two lines at once by combining a physical SIM with an eSIM. That setup has also led to a rise in dual-SIM usage, even in markets predominantly controlled by carrier-locked devices, including the US.If you already use a dual-SIM phone, you know you can set the default SIM for calls, texts, and internet access. From these, you can also choose the option that asks the dialer every time you make a call. As useful as this option is if you actively use both SIMs for calling, it can also feel cumbersome to choose a line before every call. Google has recognized this issue and is now working to solve it.
