In search of used smartphone

This is a log shot but I am posting to see if I am able to find a used smart phone someone who be willing to donate for my sister. She’s working part time hours and living alone, she’s looking for second job but it’s not coming easy. The phone she currently has, has stopped working and I am hoping to find her a used phone that someone may have just lying around. She’s not in a financial position at this time to try and finance a phone through a company as I said previous, her income is limited. Please reach out if you have anything that could help her out.
