You can add minutes or purchase a new service plan when your Straight Talk minutes have run out. This can be done by visiting the official website or via a service card. There are no rollover minutes with Straight Talk, so even if you have leftover minutes from a couple of months back, you’ll still need to put more minutes on your phone.
Log onto Straighttalk.com.
Click the “Refill” tab at the top of the page, then select “Refill On Demand.”
Log into your account by entering your email address and password. If you don’t yet have an account, create one by clicking “First-time log in or first time user” and entering your Straight Talk phone number on the following page.
Select the type of plan you want.
Fill out your credit card information and submit your payment. Your minutes will be added, and you can begin using your Straight Talk phone again.
A service card is used to refill the airtime load balance on your Straight Talk phone. Purchase a service card from participating retailers, starting at $30 a card.
