How to Verify a Clean Sprint ESN
- 1). Turn off the Sprint cell phone and remove the battery cover. Take out the battery and look at the sticker label underneath it. The ESN starts with "DEC." Write down this number.
- 2). Call the Sprint phone company at 800-639-6111 to reach the ESN department if you need to check a Nextel phone. Call 888-211-4727 for a Sprint phone ESN check.
- 3). Tell the Sprint representative your ESN and ask if it is clear. He will tell you if you are able to activate the phone.
