ference call, tap Menu > Private.

Dial an international number
When dialing international numbers, there is no need to enter
the international direct dialing prefix ('00' etc.) before the
country code. Simply tap and hold +0 on the onscreen number
pad until + appears onscreen, or press + on the embedded
numeric keypad (<Fn> + <G>).
Warning: International call rates can vary greatly depending on the
country you are calling and your network provider. We suggest you
check all call rates with your network provider, to avoid excessive
phone bills. If you are using your Acer M900DF Smartphone
abroad, roaming charges will apply. Consult your network provider
for roaming rates specific to the country you are visiting before you
leave.
Use the speakerphone
The speakerphone function allows you to make calls without
having to hold the Acer M900DF Smartphone. This handsfree
function is especially useful when driving.
To activate the speakerphone, tap Speaker On on the voice call
screen. Tap Speaker Off to disable the speakerphone.
