T-Mobile is getting ready to offer unlimited 4G no-contract data plans in the U.S., although it's not the LTE kind of 4G plans we're talking about here. The existing $70 Unlimited text/talk and 5GB data plan will be replaced with the $70 Unlimited data, text and talk plan and users will be able to upgrade to the new plan from January 9.

The fourth largest U.S. mobile operator, T-Mobile made this smart move as it understands that smartphones have become an essential part of users' lives. They look for utiltiy and entertainment on their devices and look for hi-speed data services.

The carrier promises full HSPA+ speeds all month long to users so that they can enjoy streaming videos/music/movies, video calls and online gaming. The new unlimited plan has the potential to offer an amazing experience to T-Mobile subscribers who are always using their smartphones for online-related activities and do not want their phone bills to burn a hole in their pockets.

Not to mention that it will also make users waiting for Nexus 4 from the Play Store more excited and anxious to get their smartphones.
