A lot of your work may require you to download files or upload files to e-mail them or share them with coworkers or business partners
. If you're working on a WiFi connection in a restaurant or coffee shop, you may find it hard to download the files because the connection won't allow you or just because it takes a long time. You can download and upload the files easily when using your mobile air card so you don't have to deal with the WiFi connection of the restaurant you're having your lunch meeting in if the restaurant even has an available WiFi connection. You will find that business can run smoothly and efficiently when your employees, coworkers, business partners and all the people you have to work with have access to the Internet while they're in the office, at home and on the go. Response time to e-mails is drastically longer when it also requires the person to drive home from work and turn on their personal computer before even reading the e-mail.
