We got our dd a phone when she was 9 and in the 4th grade. It's a simple track phone with old fashion texting. However, they would sometimes dismiss swim practice early and she would be stuck waiting---or the same for soccer. So now she can let us know and when her grandparents pick her up they don't have to park and go into the pool (which isn't easy for my elderly mother)---they can just text her to come out.
