Particle SIM Usage

Hello,

Is there a way to track how much data are being used by my devices every month?
I did not see anything in the console.particle.io.
Thanks.

Have you looked at console.particle.io/sims and then clicked on any of your given SIMs?

There is also this

@ScruffR. Thanks for your reply.
The console.particle.io/sims do give me an insight of how much data is used this month.
My question was more along the line of how do I see what was the usage in the previous months?
