We bought an iPhone 5c many years ago and it was locked with sprint, but we only used it as an iPod for my kids. There is a sprint sim in the phone, but we never had service on it.
Today we plugged the phone into my mac, and it updated the iOS and restored it (which we did want to do to reset the phone for my daughter), but now, it says that we don't have a sim and can't do anything until we have a sim. It does have a sim in it...I am not for sure what to do. Can anyone help?
