Both the pre-owned phones currently offered by Sprint a very small sizes marketed towards women. The number pads for dialing are shared by the keyboard. I'm ok with the small keyboard for texting, but the shared keyboard is very hard for me to use for dialing a phone number.

Because Sprint is not offering a phone that meets my needs, I am planning to buy a phone from Craigslist or Ebay with a clear ESN. I was hoping that someone could clarify whether or not I can use ANY phone set up for Sprint service, or only specific phones for this plan.

Thanks again for your responses. I REALLY appreciate your help. Thank you.
