Thank you for reaching out to us. I understand the importance of knowing your options when it comes to retrieving prior text. Once a text message is deleted from the phone it is not able to be recovered. We do store them in our systems for up to 10 days, however it does require a court subpoena in order to get the messsages, which can take some time. Since it is a basic phone there are not any outside apps they can store the info on, but many smartphones have applications that can be downloaded to save messages. I hope this explains the message saving options. Please let us know if you need anymore assistance.
