NOTE: AT&T has started to phase out 4G service in some markets. We do not have any way of knowing what areas still have 4G service, so it is always advisable to check with the local AT&T store before purchasing the RTU-1 to see if it will work in your area before purchasing this product.
If you discover that AT&T does not offer 4G service in your area then DO NOT purchase the RTU-1. Instead, purchase a hot-spot from your local cellular provider. The hotspot must have at least a single RJ45 ethernet port to connect to.
