AT&T Business's Unlimited plan for 1 line costs $65 per month.
It rides on the AT&T network for coverage.
It includes unlimited minutes, unlimited texts, and unlimited high-speed data per month. You get 5GB of hotspot data. Video streams at 480p quality.
The AT&T Business Unlimited Starter plan has deprioritized data. Having deprioritized data means you may temporarily experience slower speeds during times when the cellular network is busy. You'll resume getting the fastest speeds available when the network is no longer busy.
Taxes and fees are extra on this plan. I estimate they will add another $4.94 to the price. Your total montly bill will be about $69.94 per month.
Overall, I do not recommend the AT&T Business Unlimited Starter plan. It is too expensive for the features and data you get.
