MVNOs leave a bad taste in my mouth. More than once I have used MVNO phones in both rural and urban areas and had my phone not work while people who had real phone plans had it working. Carriers have tools to prioritize different tranches of customers and so far as I can tell MVNO customers ride the back of the bus if they get a seat at all. Even at 1/3 the price the MVNOs I've tried were a bad value.

That said, if you have a loyal customer base an MVNO product can be rolled out completely and it's the sort of thing that you could bundle with a bunch of other services of dubious value, particularly if you are playing business theater. That telehealth provider will now be able to claim they have $X million customers, which could impress investors and potential partners, and it is all the better if they don't use it because they won't incur costs to serve.

As with all things Trump it over promises and will under deliver.
