How Long Is the Test Period of an IoT SIM Card Provided by Carriers Outside the Chinese mainland? What Are the Card Usage Time and Validity Period?

For physical SIM cards from carriers outside the Chinese mainland, a test period of six months is provided (inactive period is not available). This period will not be counted into the validity period. When a SIM card gets manually activated (getting inserted into a device and powered on or activated on the console) within the test period or automatically activated after six months, the system starts to calculate the card usage time. The validity period is the same as the required duration (one or three years) of the order. Data is provided by month based on the purchased plan and is reset in the next month. The billing cycle is by calendar month for China Telecom, China Mobile, and carriers outside the Chinese mainland. China Unicom bills from the 27th of the previous month to the 26th of the current month.
