I switched from a Sprint MVNO to a GSM operator a couple years ago and then back to another Sprint MVNO several months ago. Before I left, I often had problems with connectivity. After returning, I found that connectivity problems were rare. I suspect that Sprint today is about as good as Verizon was 5 years ago, which is good enough if the price is right. In my case, I signed up with RingPlus, which charged me once when I activated my phone and has not charged me since. I consider myself to get cellular service for free, which is a fantastic price. Support leaves much to be desired, but that is to be expected at that price point.
