# End Test Mode and activate SIMs

> Activate multiple SIMs out of pre-deployment testing before their free testing period has completed. This action activates SIMs out of Test Mode, and begins regular billing of data usage and monthly recurring charges.

You can force activate SIMs out of Test Mode before their free testing period has completed. This action activates SIMs out of Test Mode, and begins regular billing of data usage and monthly recurring charges. Generally this is not needed for any SIMs except for SIMs that are on a legacy Global-1 (G1) data plan, which experience a brief disconnection when activating to update profile states.

<Note>
  **Note:** SIMs in Test Mode will activate automatically after using free data, with **no downtime or action required** on your part.

## How to end testing early and force activate SIMs

To force activate SIMs out of Test Mode, they must be on the same preconfigured data plan. Scroll the pre-deployment SIMs page to the right to see the data plan each SIM will activate into, or use filters to select SIMs on specific plans.
