Hello,

How much data an NbIoT transmission use?

I have done some tests using Nbiot sends in mqtt and coap  (without ack), and following the data usage of the cellular simcard in the operator's platform.
In these tests I've seen that one transmission of 10bytes payload using mqtt or coap, consumes about 1000bytes of the cellular packet plan. 

Is this normal? 

I thought it would consume less bytes of the simcard's plan to transmitt only 10bytes payload.

Thanks,

Hello,

What the operator calculates and charges may differ from the actual data that you measure on the device side. 
From what you write it seems like the operator may ***** at least 1000bytes each time any data is transmitted, so 1000 bytes may be the smallest data unit they *****. It definitely does not match your scenario with small data amounts and lightweight protocols. I think that you need to talk to your operator. Maybe they have better plans for your solution.
