Just moved into a new office building shared with other companies. There is absolutely zero cell service unless I go outside. IT says they're working on installing extenders throughout the floors to help. A lot of people were complaining. For now they tell us we can connect to the companies guest WiFi network. The only problem with that is the potential to monitor my phone traffic once connected. My VPN doesn't work with my company's WiFi either. I need to have service for any family emergency calls. Any ideas where to go from here? I don't think there's much I can do. I'm not sure if there are any blockers installed in the building.
