Users get 50 minutes of talking monthly. Once these minutes are used up, you won’t be able to receive forwarded calls until the next month on your billing cycle.
To check your remaining call minutes or text messages, visit your Firefox Relay dashboard:
- Sign in to Firefox Relay with your Mozilla account.
- Click Phone Number from the top right options.
The below image shows the Relay Phone dashboard, where you can check your available minutes and text messages.
