Yes, 50 GB would be able to support a professional working from home or a small family and is considered heavy usage. If you were to use 50 GB of data for a month what would it look like though? You could spend 2,500 hours browsing the internet which seems like a good many hours if that is mainly what you do. You could also stream music for 600 hours or have 400 apps downloaded. You could open and read 20,000 emails for your business if you are a professional who works at home. Or if you need to Skype the partners of your business then you could have 300 hours of Skype calls. If your family likes to watch movies then you could download 50 movies in SD for the month. Of course there will be a mix of all these options, but there are many activities you could do with 50 GB a month. The activities that will take up the most data is gaming online and streaming movies and shows on high settings. If you are worried about going over your data cap then you may want to watch how often you do these activities or do them during low volume times.
