Why do you need another?

Depends. What do you need a third one for?

The price is nice.

What for?

Tf do you need 3 phones for

No. Nobody needs three phones.

I guess it depends why? Are the other two phones not working? Are they all the same brand/model? If I were going through them at that rate, I'd consider saving for a minute and getting something like the Samsung Galaxy A-series, some of those are under 200 new

So what do you do with the two and what purpose would a third have?

I think you've answered your own question there, Champ.
