Are there any restrictions on sending bulk SMS?

A well-thought moderation system does not allow customers to send suspicious links and low-quality content that will be blocked by operators. Message check takes several minutes to make sure our service does not generate any spam. This feature can be disabled, we care about the quality of messaging, but we do not want to limit our customers. It is possible to send bulk SMS in any situation, no matter what data you would like to share with your audience.
