T-Mobile will offer new data plans for USB adapters 18 Oct: T-Mobile has made several changes in the last year-and-some to reduce the cost to mobile broadband users with laptop adapters, as well as increase the predictability of the monthly bill. That included adding a no-overage 5 GB monthly plan (throttled, but not charged or cut off), and lower monthly prices for data service. Now, they're taking a page from Virgin Mobile.
Virgin Mobile now has a $40 plan for unlimited data over 30 days with no contract required, that works with either a 3G modem or a MiFi, both of which must be purchased in advance. T-Mobile's deal sounds a bit weaker, although its data network is faster. The three options are $10 for one week and up to 100 MB, $30 for one month and up to 300 MB, and $50 for one month and up to 1 GB. These are prepaid plans like Virgin Mobile's, with no contract or overage fees.
On the phone side, T-Mobile is switching to an AT&T-style data plan, with two unlimited voice and text plans. The $50/mo flavor includes 100 MB of data; for $70/mo you get 2 GB. A minimal plan includes 1,500 voice minutes or messages (any combination) and 30 MB of data.
