Text messages, calls, emails and Ai usage consume monthly credits as shown below. Complimentary credits are added to your media wallet each month. Additional credits are added automatically only as you need them and charged to your card on file. Complimentary credits don’t roll over. Purchased credits never expire. All texts, emails and calling minutes shown are approximations based on that media use alone. Your amount of media use will vary, and will be a combination of the number of different amounts shown.
