We use a hotspot from StraightTalk, i.e. Walmart. It uses the Verizon network and runs about $50/month for unlimited data. There are cheaper plans with limited data. We don't stream movies or such, just FB, YouTube, email, and various web surfing. Works great for us.
We don't use it all the time, so we can not use for six months, or whatever, and not pay monthly fees. Then reactivate and off we go.
