So many different answers about this question Please help!!! Can I use an Iphone 4s from Sprint on straight talk? It has a clean esn, I bought from my granddaughter!!

The definitive place to get that answer would be from Straight Talk. But the answer in this case is most likely no. It sounds like your phone is CDMA or locked phone from Sprint. What that means is that phone will only function on the Sprint Network. The initial price of the iPhone is reduced by hundreds of dollars when you buy a locked phone, because companies like Sprint  expect to make money on your phone contract as opposed to the hardware.  For example, the iPhone 5s costs $199.99 with a 2-year service contract from Sprint. An unlocked iPhone 5s can run you around $800.

If you contact Sprint, they will likely tell you they won’t unlock the phone for use on other carriers. But I have seen reports from people who say that Straight Talk can get the phones to work by creating a virtual network.  Here’s where you should go to find out in just a few minutes. Go to the Straight Talk help page here. 

Then click on the LiveHelp button  on the right to talk with an Agent. Someone should be with you in just a few seconds and he or she will be able to verify if it’s possible to get your phone activated.

No matter how many different answers you hear, the only one that matters is the one from the phone provider in this case.
