You can view your plan and renewal date on your Billing page, found via the top three dot menu (on the right) on your Mobile Text Alerts dashboard.
Accounts auto-renew by default either month-to-month or annually, and you can view the date of your next charge as well as the history of your payments under the "Payment History" tab.
You can also view/edit what card is going to be used to process this charge.
If you have any questions about billing you're welcome to live chat with us or reach out to contact@mobile-text-alerts.com.
