Several calculations are performed in the following order to determine how much an account is charged for the data usage of an individual IoT SIM card:
1. Calculating Raw Data Usage
For more information on how Soracom calculates raw data usage, please see our Data Usage Calculation documentation.
Note that Soracom converts units using 1,024 bytes = 1 KB, 1,024 kB = 1 MB, etc.
2. Calculating Billable Data
Billable data is then calculated based on the minimum billing unit of the country where the data was used. Raw data usage is rounded up to the nearest increment of the minimum billing unit. This rounding occurs for each SIM card individually and not for total usage across all SIM cards on your account.
Minimum billing units for each country can be found in our Supported Carriers documentation.
3. Calculating Charges
After determining billable data amounts, Soracom charges customers for data based on the plan of their SIM card, whether that SIM card is pay-as-you-go or bundled, and the country in which the data usage occurred.
Data rates for individual countries and plans can be found in our Supported Carriers documentation.
