That could work but many Cellular providers will impose a data use cap on the service. which will then throttle your speeds after a certain bandwidth usage. So working from home with anyone else using the internet could become problematic
As far as 1o users simultaneously, sure, but their experience will be less than optimal. I work in the industry. Eventually the carrier is going to throttle back "excessive" users to ensure that all their customers get a fair slice of the bandwidth the cell tower can support. After that is when the data caps come in and your account becomes throttled all together regardless of what tower you are using.
You cant rely on service like that, especially if you are working form home. Which is why many of us still rely on home internet providers like the cable companies.
Our typical scenario here at home is needing internet for my wife or I ( one at a time because we don't have internet on our phones... shocking, I know) while the other is generally watching something on tv. Admittedly it's usually myself utilizing both at once as my wife isn't on the computer as much as me and she often isn't watching tv because she comes home from work and wants no bs noise.
But the "Pick 15 channels plus local and we'll knock $35 bucks off your $204 monthly bill" is just crap customer service and a lousy way to treat good customers. They certainly know that they aren't doing us any favors with this offer and it's the only "solution" their giving us... despite that I've been with them probably 30 years at this point.
And it's a hard call for me. We don't really have a favorite few channels or shows that we watch. I like to flip thru a lot of different channels for something interesting or entertaining that might catch my eye and I never know what that's gonna be. Anyway, they know that they got me by the balls if I want some variety in channels. Maybe this latest squeeze is related to tv viewership taking continued hits with everyone now using phones/ social media platforms, I dunno.
But this is now directly cutting into my grocery allotment and that means a reduction in my budget for sausage, brisket, cheese, and bakery treats... and that's just not acceptable.
