Hi there,
For widgets, I would firstly recommend going to your devices in RMS, choose the device in question, press on actions, management, manage monitoring templates. On the screen appeared, depending on the templates you have active, you need to change the period of updates to 1 minute (it is 5 by default). (see screenshot)
After that, click save. Wait a little bit for the system to sync.
Go to that devices dashboards, and when you create a widget, the values to choose would be these (See screenshot)
When you press save after that, you will be able to see values increasing every minute, for sent and received data, for both sim cards. Do note that the data presented there is in bytes, and 1000 bytes is 1 kilobyte. I am only adding this for easier conversion, and do want to note that conversion in the app itself is on the agenda for our RMS team for future updates.
Regards,
Arturas
