Hey guys, Long story short, I have a business (more like a hobby) that requires an internet connection for planned appointments. I may have a few appointments a week, or a few a month. Since I may not be in the office for weeks at a time, I would rather not pay a monthly internet bill. And I don't believe there are any cheap business internet plans. So I figured tethering/mobile hotspot might be the best option. Do you guys think it is? Should I pick up an old iPad mini cellular or is there a reason to get the newer iPads in terms of mobile hotspot use? My iPhone has the unlimited plan, so AT&T won't let me use tethering/mobile hotspot. Any advice appreciated!
