Is it possible to bring in different kinds at the same time when I buy electronics directly?

I'm going to buy a drone and a smartwatch directly

As far as I know, radio wave certification is required and one is exempted at a time.

I was wondering what happens if the types are different like this.

Is there no problem because it's one each?

Or do you think two came in because the radio wave certification number 1 is the standard for delivery?

As far as I know, any other type is fine

I thought both of them wouldn't work because they only use one at a time if they needed radio certification
I know it differently from my superiors

I bought a different kind
I don't know if it's working or if it's too cheap
