I live in a rural area and my sprint service is horrible here. They have been having tower problems for months. My question is, is there a way to force my phone to roam as my roaming signal is excellent when it roams. I have a samsung s3.
The only way to force roam on Sprint Android phones is to root the phone and install Roam Control. Right now the app is not working on the GSIII, but the dev is aware of the issue. Roam Control | Making Android phones usable since 2010
