That's a good point. And if your non-compete was that clear cut you wouldn't have a problem. Yours isn't clear cut. I know how to define "ice cream" and I know how to define "airplane" but I have no idea what "enterprise mobile platforms" are. Do you?
For all I know it could be one of these:

Or it could be software that you download for your phone.
But you already know what business your employer is in so if there is something that says don't compete with the employer's business, that could be enough.
Anyway, as has already been said, the entire agreement has to be reviewed for its intent.
The wisest course of action is don't compete with your previous employer unless you get a written waiver of the non-compete agreement.
