When AT&T revamped its data plans this past summer, feelings were mixed to say the least. While the Internet erupted with opinions on both sides of the fence, T-Mobile seemingly sat back and made notes. Letting AT&T take the heat appears to have been the right move, as rumors suggest that the carrier intends to do data right. In addition to T-Mobile’s standard $30 unlimited smartphone data plan, TmoNews reports that a new cheaper option will become available next month. According to the report, $9.99 will afford less active smartphone users 200MB of data per month. While there is no word on what data overages might cost, customers will supposedly have the option to upgrade to the $30 unlimited plan at any time. If this rumor holds true, expect the new cheaper option to become available toward the end of November.
