Upon reaching the limit, your SIM will be paused by the system. This means that the SIM can no longer send SMS or data until the SMS limit is increased or until the next billing period begins. The organization’s owner will also get an email notifying them of the pause. The default SMS limit is 100 outbound SMS per SIM. Limits are tracked across all installed profiles on the SIM. When a SIM reaches the limit you set, it is paused.

​
What happens if a SIM reaches its SMS limit?

All profiles on the SIM will be paused until the SIM’s next billing period. To unpause the SIM you will need to increase the SMS limit, which will unpause your SIMs. This process typically takes around 10 minutes before the SIM will resume activity on our network.

​
What is my SMS limit and can I change it?

The default SMS limit for all SIMs is 100 outbound SMS messages. SMS limits cannot be removed from a SIM.

​
How do I request an SMS limit increase?

Limited access. Customers with an active contract can request an SMS limit increase by contacting our support team.

​
How do I update an SMS limit using the REST API?

You can decrease the SMS limit on a SIM using the REST API, or increase the limit back to 100.
