This thread is rightfully meant 4 those who have java fones with PTT. Go to the menu of your fone scroll to PTT,set 2 default. Go to ur browser or application. When browsing,hold the volume key, it will pop up a screen asking you to add contacts to ur PTT either manually or 4rm contacts. If u have your credit balance checker(*556#/*123#/#124#/*223#) in your contacts before. Retrieve it or you enter it manually and later retrieve it from the contancts. When u've done that, press the green button and watch it happen. Let ur testimonies be my reward.
