With Verizon 4G and Netflix sometimes we can watch an entire 2 hour movie without a buffering pause; other times it might happen once or twice for ~1-3 minutes. The speed of the cellular network is not constant and can drop to zero for a minute or two. Netflix uses a buffer and an ability to change your resolution on-the-fly (with you hardly noticing it) in order to handle changes in your internet download speed so the number of actual "breaks" in a 2-hour period are usually small. When that does happen it's a great excuse for a "nature calls" break anyway. :B
