I just checked on the Consumer Cellular web page, and their new plan for seniors (50+) with AARP is unlimited talk, unlimited text and unlimited data for $57/month, with data after 50 GB subject to reduced date rate. So I just switched. We've been with them for at least 15 years (perhaps a little longer), and it's worked very well for us.
Our old plan at the same price only allowed 10GB of data, though the other two were unlimited. The 10GB wasn't a problem for us, since we've NEVER used even half that much data via phone. I only switched because it was the same price.
BTW, it's the same price as when we started with them having a very limited talk and very limited text and 400MB of data.
