I laugh at those ads. The add promises to charge you half for a month service. At $72 per month as if that is cheap. Let me tell you what I am charged per month for cellular service. I pay $15.38 per month for full service. I used to pay them about $50 per month. They called me one day and told me I should pay only $15.38 per month. I thanked this firm for helping me and for years now, I pay just over $15 per month for full service. The firm I use starts with T for the curious. Ask me if you want help. But pm me only. If you are curious, you must be retired to get it this cheap.
