I'm rocking two $6/mo plans, on my $30 LG Realm and a Samsung M500 flip phone from 2007. I was using a qwerty slider instead of the flip phone but I realized it was just excessively large and butt-dialy and I almost never used the qwerty anyway...might as well use the smaller, sleek flip phone instead. Only complaint is it's not compatible with modern data connectivity but it keeps trying to connect and producing an error that I have to dismiss even though I have data turned off. Meanwhile the Realm is still chugging along, slow as a motherfucker but FIDIL.
