These steps are for Google’s Phone app; another Android phone app may use different labels or controls. Google’s Phone app help describes merging current calls and notes that calling features can depend on the device and carrier.
What you can do while the calls are active
Google’s in-call controls include options such as muting, putting a call on hold, and switching between calls. If a Bluetooth headset is connected, you can select it as the audio device. A headset is optional and does not enable call merging.

Why the merge button may be missing
If you do not see Call merge, first check whether your carrier supports conference calling on your line. Also confirm which calling app you are using: the instructions above apply to Google’s Phone app, while another dialer may present different controls. Consult your carrier and the help for your specific phone app if the option remains unavailable.
