If I get an iPhone, will I be able to keep my $25 Virgin Mobile plan?

I got a VM phone and plan a few years ago when 300 talking minutes and unlimited texting and data was still $25. Around a year ago, they changed it to $35, but customers who already had the cheaper plan got to keep it. My phone broke a few months ago and I got a new one, and because I kept my plan and just updated my phone, I got to keep the $25 plan.

However, I'm considering getting an iPhone for Black Friday. It's on sale at Target for $100 less than usual.

I'm not finding anything about having to move up to $35, especially because iPhones are on the same plans as other VM phones. Still, I want to be sure. Unfortunately when I called, I kept getting an automated message and couldn't talk to a real person to find out.

Does anyone know for sure?

I highly, highly doubt it. Unless you're willing to pay $650 for an unlocked phone.
