When it comes to the reliability of Consumer Cellular's network, customers can be assured that they are in good hands. The company uses either AT&T or T-Mobile networks, both of which have great coverage across the United States. Here are a few reasons why Consumer Cellular's network is so reliable: AT&T and T-Mobile have one of the largest nationwide footprints with 4G & 5G LTE service available in most areas. Both networks offer strong customer support with an average response time of just under 2 minutes and 24/7 technical assistance for any issues that may arise. Consumers are able to take advantage of unlimited talk, text and data plans on either network at very competitive prices compared to other carriers. Their cellular towers utilize advanced technologies such as Voice over LTE (VoLTE) and HD Calling to ensure clear calls even when traveling long distances or through buildings where signal strength can be unpredictable.
