Average is one thing, but actual usage may be something else. For instance, I average 4GB, but range from less than 2GB up to 10GB some months, when I travel. It's possible 2GB would be enough, but with highs and lows, you might need 4GB. You need to look at that, then run the numbers based on a tiered data plan of 2GB for $30 or 5GB for $50 or a Share Everything plan of 1GB for $50, 2GB for $60, 4GB for $70. Also, with the Share Everything plan you get free tethering/hotspot if that's of interest to you. With unlimited data, you have to pay $30 for unlimited tethering/hotspot or $20 for 2GB. That's in addition to your data plan. If you go with a tiered data plan, you can purchase the tethering/hotspot feature from Verizon or use a 3rd party app if you can find one that works.
Having written all of this, If I was you, I would be inclined to keep my current voice and text plan and switch to a tiered data plan of 5GB for $50. That would be an increase in price of $20 per month versus your current plan, but would get you a new phone for $200 instead of $650, for example. After watching your data usage for a few months, you could cut back to 2GB for $30 or switch to Share Everything and 2GB for $60. Sorry if this is a little confusing, because it is.
