The "general1 off-topic" explanation text already says
Questions on Android Enthusiasts should be asked from a end-user point of view and within the scope defined in the help center.
And under the "What about other Android-related questions?" section, we have this for the 7th item
- Android-independent questions, such as "Does Carrier X have prepaid plans?"
I think it's more straightforward to close as the reason of "general off-topic", and optionally leave a comment to tell OP to read help center. Furthermore both reasons are rarely used so I think it'd be cleaner to merge them.
1. All SE sites have a similar close reason to this.
