Samsung MM-A900 / SPH-A900 / Ace

Do you mean that you have switched phones and you want to see how many minutes of your total minutes this month were used on your new phone? If so, I have no idea how to do that.

I did switch phones. However here was a manufacturer defect in the outer LCD, so I was going to send it back to where I bought it for an even exchange. One of the company's policies for returns is that you don't have a total talk time on the phone that exceeds 30 minutes. I can't figure out how to find out the total talk time that's been used on the phone so far.

If you call Customer Care, they should be able to tell you how many minutes you have used on the phone. They know when you swapped your device and they can see how many minutes you have used since the swap. I don't know of any way to get this information from the phone itself.

On Sprint phones, the only way you can see total lifetime of the phone's usage (i am assuming that is what you want to see: how many minutes you've used the phone since you purchased it) is by taking it to a sprint store and having the tech hook it up on the ccs (brand we use) machine. other than that, sprint does not have an option on the user menu. why? i do not know. they just don't. so if you feel like waiting two hours.... that's how.

try ##786#. click 'system' its listed under life timer
