T-Mobile CEO John Legere is back to business, kicking off the Un-Carrier 9.0 keynote with new plans for business customers.

Currently, T-Mobile controls a meagre percentage of business customers with most going to AT&T or Verizon for business contacts. Legere is hoping these new easy to understand plans will win T-Mobile customers the same way it has on the consumer side of the carrier market.

"We are going to do for businesses, what we've already been doing for consumers," Legere said at the Un-Carrier event. "Eliminate pain points and force change."

It starts with a simple plan: 10 lines for $160 per month. Each additional line costs $16 up to 20. This is great for small businesses but it gets better as T-Mobile scales the plan.

The price drops to $10 per line for 30 to 1,000 lines, meaning businesses will be able to outfit employees with a smartphone and only have to pay $10 per month to have unlimited texts, calls and 1GB of data.

Even after 1,000 lines, T-Mobile will not move into backroom negotiations. It will only offer the flat rate of $10 per extra line. This is a smart move as Verizon, AT&T and Sprint all tackle business customers in different ways, negotiating different contracts for different customers.

If businesses want to upgrade the package, T-Mobile offers 2 GB of data for an extra $10 per line, an extra $30 per line for unlimited 4G LTE data.

For small to medium sized businesses, T-Mobile is offering a pool of 100 GB of data for $475 per month. Businesses can once again acquire more pool data for the same price.

T-Mobile is throwing in a few freebies when a business signs up, including a free .com domain from GoDaddy and a free .com email address from Office 365.

This is a big step into the business market but will T-Mobile be able to surpass the troubling reputation of its network and win over business customers?
