can i use my current mobile phone with cricket service?

If your phone has already been flashed to Cricket your phone can be activated for Cricket service. However, since your phone was designed to work on another carrier’s network not all of the Cricket network features may work even though the phone was flashed to Cricket’s network.  If you would like to experience all the features Cricket network has to offer you may want to consider purchasing a Cricket phone. Cricket only supports voice features and text messaging for non-Cricket phones.
