A data usage limit defines the total amount of data the device can consume during a billing period. When a SIM reaches the limit you set, its data usage is paused. The organization’s owner will also get an email notifying them of the pause. Data usage limits are checked at the close of each data session. If the SIM’s data plan has included data, the data limit has a minimum value of that included data. This value is the overagelimit parameter returned in the REST API, and is checked above plan included data amounts.

​
How to set a limit for a single SIM

  1. Open a SIM from the SIMs pages or using global search.
  2. Click the Manage SIM menu in the header and choose Set data usage limits.
  3. Enter your settings:
    • Overage limit: Cap in bytes/KB/MB/GB (SIM pauses when reached)
    • Threshold alert: Optional warning level (does not pause)
    • SMS limit: Optional cap on SMS usage
  4. Confirm the update.

​
