I am calculating the data plan i will need to send data from an Arduino MKR NB 1500 to the cloud.

I am wondering if my calculation is correct, any feedback is appreciated.

Let's say we want to send 2 integer values every second. An integer value on this board uses a 32 bit value. So a total of 64 (32*2) bits are needed, which comes down to 8 bytes (64/8).

There are 2.592.000 seconds in a month. So a total of 8 * 2.592.000 = 20.736.000 = 20.7 MB

I suspect there are extra bytes needed in every packet send, does anyone have an estimate for this?

Thanks in advance!
