3-Way Calling lets you connect a third person to your two-way conversation. There is no additional cost for this feature if used for calls within the U.S., Canada and Puerto Rico. If you call an international phone number, you will be billed the same rate as your calling plan.
For billing purposes, a 3-Way Call appears on your usage as two separate calls that happen at the same time.
Because a 3-Way Call is two calls at one time, it requires enough bandwidth for two calls simultaneously for a maximum bandwidth of 180 Kps. If your 3-Way Calls are not successful, use the Bandwidth Saver to adjust your settings.
I am a bit slow when it comes to technology, but my children try to keep me in the loop. As my daughter watched me making call after call to relay information between my two sisters, she informed me it would be much easier if I just connected us all through a 3-Way Call. My children are brilliant.
