I have been frustrated that I could not charge the time period my dumb phone would ring for before diverting; a few seconds was damn dumb imo. Two or three rings wasn't even enough time to get it out of my pocket This fixed it; sent to me by my daughter Press **61*101**[15, 20, 25 or 30]#. 2. Press the call/send button. For example, to make the phone ring for 20 seconds, type **61*101**20#. 30 Seconds? **61*101**30#. Easy! To reset your phone to its original call settings, enter **004*101#. So why couldn't that be installed on the phone?
