Hi cakrom. My name is Straight Talk Charisse and I will be addressing your question. Here's teh instruction on how to use the speakerphone:
1.During a call, tap "Speaker."
2.To turn the speaker off, tap "Speaker" again.
Note: You know the speaker is ON if you see the line under "Speaker" turn blue.
