Netflix will soon come bundled with your T-Mobile plan

And it’s limited to one Netflix subscription per family account.

T-Mobile US Inc. said Wednesday it will offer family-plan subscribers free access to Netflix Inc.’s streaming-video service, the carrier’s latest bid to lure wireless customers away from its larger rivals.

Are there any caveats? .

T-Mobile and MetroPCS customers in affected areas of Puerto Rico will get calls, texts, and unlimited data for free from September 6th through September 8th. With this plan, you can stream on two screens at once in HD resolution.

How to I sign up? .

Customers that qualify for Netflix On Us can enroll online, in a T-Mobile store, or by calling T-Mobile customer service starting September 12. This time around it’s nothing earth-shattering, but something that will surely be considered a welcome addition by many T-Mobile subscribers. Four lines are $160 – taxes and fees included. Partnering with fellow “disruptor” Netflix means giving customers something they want – more mobile video, the company said.

The new plan was announced on a conference call with T-Mobile CEO John Legere going off on his usual profanity-laced tirade against his competitors. Subscribers with two lines pay $60 per line, while those with three pay $47 per line. If you get this plan on Netflix, then it will cost you $9.99/month, so if you’re a T-Mobile customer, then you can save around $120/year.

T-Mobile customers expressed their understandable happiness on Twitter. According to T-Mobile, during times of data congestion – say prime TV viewing time – the top 3 percent of data users ( 32GB a month) can expect to see “reduced speeds until next bill cycle”. Since speed is all important for high-quality video-streaming, this is all for the good. Also, there is a fairly big catch – T-Mobile limits smartphone video streaming to 480p. You can of course watch Netflix in full-quality using your home internet.

Nevertheless, the promotion is likely to give at least some lift to Netflix’s USA subscriber figures.
