T-Mobile is making some big news today, rolling out some rate plan changes and announcing a new deal.

First up, the T-Mobile One plan is becoming the Magenta plan. Pricing for the Magenta plan is the same, meaning it starts at $70 for a single line, goes to $60 per line for two lines, and so on, and the features are largely the same, too. There's unlimited talk, text, and 4G LTE smartphone data, T-Mobile Tuesdays, and free data and texting in more than 210 countries.

There's also a Magenta Plus add-on, and it costs $15 per month for one line or $10 per line per month when you add it to two or more lines on a family plan. Just like T-Mobile One Plus, Magenta Plus gets you 20GB of 4G LTE mobile hotspot usage, HD video streaming, unlimited inflight Wi-Fi, and faster international data.

So what's different about Magenta? The first change is that the plan now includes 3GB of 4G LTE mobile hotspot usage each month, with 3G speeds after you use that 3GB. The T-Mobile One plan only offered mobile hotspot usage at 3G speeds, so that's an upgrade.

The other Magenta change involves Netflix on Us. Because of the Netflix price increase that was announced earlier this year, the Magenta plan for families now includes Netflix Basic. This Netflix plan includes streaming to one device at a time and does not offer HD streaming.

Upgrading to Magenta Plus will get your family the Netflix Standard subscription, which includes streaming to two screens at once and HD streaming.

It's also worth noting that existing T-Mobile One subscribers with Netflix on Us and the Netflix Standard plan will get the $2 Netflix price hike passed through to them starting in July. Customers who don't want that price increase can turn off Netflix on Us or change to the Magenta plan.

T-Mobile's other big news today is the Discount Match deal. With this offer, T-Mo will match the corporate, affiliate, military, or senior discount that you're getting from AT&T, Sprint, or Verizon and apply it to a Magenta or Magenta Plus plan.

Discounts matched dollar for dollar in $5 increments, up to $15 for a single line or $30 for multiple lines.

To get the Discount Match deal, you'll need to visit a T-Mobile store and bring in your latest AT&T, Sprint, or Verizon bill. A T-Mobile employee will then verify your discount and help you switch to T-Mo.

Both the new Magenta plan and the Discount Match promo launch on June 2nd.
