How do I verify a Sprint ESN is clear?

For anyone who has looked bought a previously owned Sprint phone it's hard to know if the ESN is clear or not before truly activating. www.Checkesn.com provides a 100% reliable and easy way to verifyif the phone is truly activable. Nothing against the Sprint customer service employee's that you will speak with on the phone. One of the Sprint employee's told me they had 3 systems they had to check to see if it was clear, and one of the systems it was hard to tell if it was previously activated or currently activated. This service (for a small fee) will verify directly in the Sprint ESN database if it is truly clear or not. This can save you alot of headache in knowing if the handset can be truly activated or not, which will save you money and time in the future. The company also provides volume pricing and allows you to submit a large amount of ESNs at once. Check the service out for yourself. It has worked for us!
