Anyone have much experience with usage in rural areas such as frequent travel to or live in one? I live in Mississippi. Between the T-Mobile and Sprint coverage here, there is a lot of the state shown with no coverage on the fi map. Sprint being the worst. Sprint relies on a lot of partner coverage here. So the areas on the fi map show no coverage but I know Sprint and US Cellular have partners here that provide coverage in those areas. I would like to give fi a try but all that blank coverage makes me nervous. I've read that some fi users will get partner coverage but data is restricted to 3g or 2g speeds or none at all. Any truth to that? Also if it's true why doesn't the fi map reflect that. Anyways, any input would be appreciated.
