June 11, 2026 Have had this service for a month. Has been down twice. Restoring service has been so time consuming! I have spoken to 4 different people who have been in different places. While they are very kind and polite, the system seems to not be efficient.

May 02, 2026 When we moved to our new house, we needed a reliable internet service because my husband and I work remotely. The house is semi-rural so we were worried about getting good service. We ended up going with our phone service provider, TMobile, and getting something like a hotspot instead of a router. So far the internet has worked reliably with minimal outages and satisfying speed between work, streaming, and gaming. We have never used this type of internet before.
