I have two parents that are operating on flip phones from about 8 years ago and I would love to bump them up to a good WP. What I need to know is a good WP on a month to month plan that is affordable. I have a 920 but the expense does not equal the use they would get out of the phone. I bought them a tablet and they check the weather and play myshong. If someone could give me some good info on a WP on a months to months network ( 50ish a month) I would much appreciate.
