That’s exactly how I handle my ‘mobile office’ setup when I’m on the road. It’s much easier to secure the source of the internet than to manage five different devices. It also keeps your data usage private from the mobile carrier, so they can’t see what kind of devices are connected or what you’re doing with the data. For anyone using portable IoT devices or tablets in public spaces, this is a much more professional way to handle security. It creates a small, private bubble of internet wherever you happen to be.
