Our phones are from Tracfone and use the Verizon network. Our average cost works out to ~$16/mo each. For data, we have two hotspots, one is on AT&T's unlimited 4G/LTE data Connected Car Plan at $20/mo, and the other is on Verizon's prepaid unlimited 4G/LTE plan at $65/mo with autopay. Both prices plus tax and fees. Both of our Android phones have VOIP apps installed that let us use our hotspots for phone calls at no cost. That particularly works well when we're in a weak Verizon area, but a good AT&T area. Over the past few years, we've only rarely found an area where only AT&T or Verizon work, but not both. Most places we've been both work acceptably well, although one is usually a bit better than the other.
