Don't use push email. Fairly vanilla user. I call, get calls, and voice mails. I check weather, stocks, and very seldom emails. I look up when the first is on the calendar and use the calculator. I don't have any apps that did not come with the phone. I use Safari once a month when I'm bored waiting for something. Your answer is very complete, it's just I don't do much of that stuff. Oh, I text my sons every six months so they don't think that I am from the stone age. 😉 But maybe I am.
I don't see why anyone would call their cell phone provider from a different phone to pick up emails. For a landline voicemailbox, yes all the time, but not a cell. If someone wants to do that they should be able to set some option to do it, fine. That's good design. But it is a design flaw to have 7gig of storage and be told you have no room left. There is no reason that my voice mail storage should be limited by some other site somewhere else on the planet. My email storage is not limited to some email server somewhere. Email design is decades old, stone age even, and it doesn't run out of storage until your hard drive is full. The reasons to store voice mails for later reference are the same as for emails. Just my $.02 worth.
Thanks for being so helpful, as everyone here is.
