Connectivity charges can occur complicated. Knowing the details can help you understand and setup your IoT deployment best as possible. 

Billing period

The billing period for all SIM plans is one calendar month. Meaning all SIM plans will renew at 00:00:00 hour (CET) on the first day of the month.

Proration

All our SIM plans are prorated to benefit our customers. Let’s say you activate your SIM card on October 16th, and your SIM is on a €1/month SIM plan.

(31 days in a month - 15 days unactivated) / 31 days =52%

Charges in this example: 0,52 * €1 = €0,52 

Rounding

We round data usage in two ways: per session and per Call Detail Record.

• All data sessions are rounded up to 1 kilobyte (1000 bytes).

• Every 6 hours a Call Detail Record is generated for open data sessions. Since it closes the session, it rounds up to 1kb.

We encourage you to use this information to your advantage when setting parameters for you IoT setup. E.g. log several sensor readings and send them all at once (this will also improve its battery life!)

SMS Charges

To charge SMS, we count the number of SMS’ sent. Only charging the Mobile Originated SMS’ (sent from device) and Platform SMS’ (sent from SIM platform).

Pricing for SMS:

SIM states

There are 4 SIM states that you can assign to your SIM card. The different SIM states have implications on service- and billing state.
