T-Mobile on Tuesday detailed various deals that will be available on Black Friday and Cyber Monday, which you'll definitely want to know about, but the chief highlight might actually be that it's offering three free months of unlimited data to customers, though with a small catch.

T-Mobile said "every single one of our postpaid Simple Choice customers" will get "unlimited high-speed data" for three months beginning December 1. You just need to be a customer as of November 23 and need to use the new Binge On feature, which downgrades video to 480p. Tethering isn't included.

In terms of Black Friday sales T-Mobile is offering the Alcatel Pixi 7-inch 4G LTE tablet for $0 down and $0 per month so long as you get a data plan with it. The same deal applies to the 32GB Samsung Galaxy S6, which is $0 down and $0 per month so long as you buy service. T-Mobile will also offer $100 off the UE Boom Bluetooth speaker between Friday and Sunday.

On Cyber Monday, T-Mobile will offer the iPhone 6s and iPhone 6s Plus with 64GB of storage for the same price one would typically pay for the 16GB model. The same applies for the 128GB options, which will cost as much as the 64GB models. The $0 down Galaxy S6 offer from Black Friday will also be an option.

Not too shabby, worth considering this week if you need a new phone/tablet.
