How to Use Three-Way on a Metro PCS Phone
Metro PCS offers cell phone service features like voicemail and three-way calling. Three-way calling allows you to conference in a third party while you're on the phone with another person.
Call the first party. Once that party picks up, place them on hold. Select the "hold" option from the menu on the lower right corner of the phone.
Call the second party. When the second party is on the line, go back to the menu. Click the "hold" button to bring the first party on the line.
Talk to the first and second party at the same time.
When one party is ready to hang up, your call with the other party on the phone will remain intact. If you hang up first, all parties will be disconnected.
