A good business Cintas has two main businesses -- managing the uniform needs of customers and providing safety and first aid equipment. The uniform side of things makes up over 85% of revenues, so this is the most important business to watch.
Verizon Wireless operates a 4G LTE network, which, as of January 2016, covers about 98 percent of the U.S. Before their LTE network was launched, they operated an exclusively CDMA2000 network (the other major CDMA2000 carrier in the US being Sprint).
If you have a Verizon 3G modem and you're in a place that isn't getting 4G any time soon, stick with what you have. But if you live in or travel to one of the cities covered by Verizon's 4G network, the Pantech UML290 is your best bet.
