My husband and I often do not recieve incoming calls, cannot make text messages take forever to send (and sometimes wont.) Recently I had an emergency on the road, and my husband was at home and did not recieve my call. Its also a chore to hunt for signal around the house. The internet service is terrible too, and I usually only have "1x" in my house, but 4glte sometimes. We live in sort of risk area, but signal is fine a couple miles down the road. What can I do to improve signal?
