One small businessperson at the event complained that his T-Mobile Samsung Galaxy S3 had problems with in-building reception.
Legere acknowledged that T-Mobile is still expanding its coverage.
There are no overages, and businesses are just charged by the gigabyte of use.
Business customers will also get a Go Daddy domain, a mobile-optimized website, and an email mailbox provided by Microsoft, on their own domain.
They're inexpensive and simple, requiring no negotiation, which T-Mobile CEO John Legere said was a major drawback of existing business plans.
"70 percent of business customers say [the buying process] isn't transparent enough ...Legere said T-Mobile will lean hard into next year's 600Mhz "incentive auction," but that spectrum will probably be built out between 20.Legere has been lobbying the FCC to make sure the auction rules set aside some spectrum for companies other than AT&T and Verizon Wireless.T-Mobile on Wednesday announced a new set of low-cost business plans and some deal sweeteners for consumers at its "Uncarrier 9.0" event.The centerpiece of the event was a new set of wireless plans, primarily for small and medium businesses.“T-Mobile understands small business owners have unique wireless needs that require customized solutions to fit diverse budgets,” said Matt Millen, vice president of small and medium business sales at T-Mobile USA.“These new simple and flexible multi-line rate shared plans, combined with award-winning customer service and America’s Largest 4G Network, deliver a great value for small businesses.” The new plans are ideal for small business customers that have wireless usage on multiple lines.the best price is the only price, for everyone," he said.Here's how it goes: Businesses must order at least 10 lines to get the special pricing."We will get low-band spectrum in the incentive auction," he said. nobody can get more than 20Mhz and the small player gets a chance." For now, coverage hopes rest on T-Mobile's 700Mhz spectrum, which covers 190 million people.That spectrum is much more like the airwaves AT&T and Verizon use to penetrate buildings.
