It's actually fine for calls once it actually connects. It's that connecting part that fails so, so often. And don't bother leaving it on--once you leave one wifi network's range and enter another one, it'll break again and you'll have to switch it to cellular only and back again. Multiple times. And then you just give up, because sometimes no matter what you do, it can't be coaxed into being "ready for calls."
