It will take some time for the device to be recognized! If it's an unlocked device, it may not ever show up, but assuming it's T-Mobile is just needs some time to update!
Thank you for the response... It's been about 24 hours since I put in the sim and I'm just a little worried that there was an issue with the imei or something causing this. Hoping in a few more days it will show up.
Don't think it is unlocked as it was said to only work with Tmobile or Metro pcs
Is it possible to run the imei directly through T-Mobile to put me more at ease knowing it is legit? Or if there was an issue, like money owed on it, would it even work? The seller is a metro dealer and hope it is clear.
