Consumer Cellular offers several different data options, all of which have monthly data limits. If you go over your monthly data allowance, you will be billed an additional $5 for each extra GB used, plus you may also experience slower data speeds after 10GB of use. Currently, the maximum amount of data available in any billing cycle is 18GB.
To avoid incurring additional charges, make sure you are keeping track of your monthly data usage, as well as connecting to any available WiFi network. Using WiFi is one of the most beneficial ways to conserve data.
