Ok so right now I pay 12-13 bucks a month for my phone and internet. It is good for surfing the web and playing certain games but I have recently begun working for companies that require video chat and video conferencing a couple times a week. I need an upgrade. I have a few options. One is a USB network card supplied by a company, another is to buy a phone and use it as a hotspot. Or finally upgrade what I presently have to a higher speed but I have to research exactly how fast a speed they can provide. I would think that using a phone as a hotspot would be incredibly fast internet speed and convenient but also the most expensive. Any thoughts ?
