You also have an option to enable factory test mode where your devices are pre-activated and allocated with a fixed amount of free data traffic. During factory test mode, there is no SIM
hosting fees and data charges, allowing you to test device connections during QA processes and ship preactivated devices to customers without incurring connectivity costs.
Once your devices use up the free data after being deployed, the EMnify SIM cards automatically switch to “active”, and only then your monthly billing starts. There is no need to activate your SIM cards when using factory test mode.
