According to a BBC report, US wireless carrier T-Mobile’s newly launched unlimited talk, text, and data plan -- T-Mobile One -- could potentially violate Net neutrality regulations.

The issue with the T-Mobile One plan which has reportedly caught the attention of Net Neutrality regulators is that the plan, starting at $70 per month, allows users to stream only standard definition videos; with an additional cost of $25 per month enabling them to avail the advantages of high-definition video streaming.

The additional cost which T-Mobile is charging under the new plan for high-definition video streaming could potentially run afoul of the Net Neutrality rules which disallow broadband providers from speeding up or blocking connections for a fee.

Though T-Mobile has not been found guilty as yet, the recent accusations that the company’s T-Mobile One plan could likely be violating Net Neutrality regulations marks the second instance in which the company has been under the scanner for Net Neutrality breach.

Earlier, in January this year, T-Mobile’s apparent Net Neutrality violations pertained to its Binge On plan. The plan’s main feature raised questions with regard to violation of Net Neutrality because of its provision for unlimited low-resolution video content with partnered firms; thereby indicating a giveaway of data away through zero-ratings programs.
