I use Google Fi and they give you unlimited talk and text for a flat $20 a month. Data is $10/GB. You decide when you sign up how much data you need per month (e.g. you might decide that 1GB is enough for you, in which case your total monthly bill will be $30, plus a bit more for taxes and fees of course). If you do not use all the data you signed up for in a given month, you get a refund for the unused portion. It uses the Sprint, T-Mobile, or US Cellular networks whichever one has the best signal for you at any given moment. Handoffs from one carrier to another are done on-the-fly and are supposed to be seamless (i.e. if you are on a call via T-Mobile and you wander in to an area where Sprint is better, the call will hop onto Sprint and you won't lose the connection). It also supports WiFi calling so that if you are on WiFi, your calls go over that instead of the mobile network (and sound great by the way, at least if you have good WiFi). Both the wife and I use it and it is the best we have found so far South of 466A (We live in the village of Sanibel)
