The version of the number of characters per month is limited to 1W characters, if not enough to use the official website to subscribe to additional use of the number.&#x20;

Subscriptions can be stacked, stacked based on the user's Email address, for example, you subscribed to 200,000 characters, just in this subscription period you can use 200,000+ 10,000 of the number of characters. During the period you can subscribe to multiple times, such as again subscribed to the 10W, the number of available 100,000 + 200,000 + 10,000= 310,000.&#x20;
