Is there a keyword limit for Unicom SMS?

Unicom's mobile phone card has no keyword restrictions for sending short messages, but the short message sending function may be temporarily restricted under the following circumstances:

1. A single Unicom user sends short messages within one hour at any time (regardless of whether inside or outside the network): no more than 200 on non-holidays and no more than 500 on holidays. (Holidays refer to major festivals such as Spring Festival, New Year's Day and National Day)

2. The maximum amount of information sent by a single Unicom user per day (whether inside or outside the network): no more than 1000 on non-holidays and no more than 2000 on holidays.
