In the pnw, verizon seems to have a much better network in rural areas as opposed to ATT Sprint at least IMO
Be tough finding a cheap rate based on your requirements of a lot of streaming, web use
I bought a throw away phone, which was not bad, at Walmart for around $60 and pay $50 a month for a good deal of service. On verizon. no contract. They advertise the $60 a month as unlimited but have no first hand experience if it is truly unlimited
