I can't add minutes on my straight talk ZTE z797c?
- Go to your Straight Talk phone's "Prepaid" menu and select the option "Add Airtime".
- Launch the browser on your Straight Talk phone and select the option "Refill My Account".
- If your phone does not have a "Prepaid" menu or the "Refill My Account" option, you can continue to go to www.straighttalk.com/Refill or contact our customer care center at 1-877-430-2355 to refill your My Account.
Hope that helps!
