It should work fine on your 9700
Sorry to hear about your troubles migrating Role Call to your new phone. Role Call should work on your 9700. Is it possible that the BlackBerry Tasks app is not installed on your 9700? Role Call needs the built in BlackBerry Tasks app in order to run. Also, the newer versions of Role Call should give you some sort of message why it can't run. Is it possible that you installed an older version? Please check that you have version 22.214.171.124 or 126.96.36.199. Please feel free to contact support if you are still having trouble.
