you're calling it `MULTI_SIM_SUPPORT` everywhere, but really the presence of `navigator.mozMobileConnections` does not mean the device has multiple SIMs. it just means that the developer is trying to figure out the [network info](https://github.com/mstriemer/app-validator/blob/6ef5950d/appvalidator/testcases/javascript/predefinedentities.py#L63) (i.e., SIM information).

I'd suggest renaming that here and elsewhere.
