Just in time for the release of the HTC myTouch 4G Slide, T-Mobile USA has announced its new Value plans, which will be available from July 24 with up to 10GB of high speed data to make smartphones more affordable for the masses and less confusing for customers.

If you sign up to a two-year agreement with the network, you will be able to choose a plan which offers a selection of talk options, unlimited texting and unlimited data. That unlimited data doesn't have any fair usage policies attached, but it will only be high speed for the first 2GB, 5GB or 10GB that you use, depending on your plan. After that, it will drop down to T-Mobile's lower speed network.

The good news is that if you do use up all of your high speed data, you won't be charged for any successive data that you use for the rest of the month after dropping down to the lower speed network. This means that there won't be any unpleasant surprises waiting for you when you open your bill at the end of the month, making it ideal for families to use. John Clelland, senior vice president of marketing at T-Mobile USA said:

T-Mobile is committed to making the always-on benefits of smartphones and tablets more accessible and worry-free for all Americans. Customers want to enjoy all that the mobile Web has to offer, but they don’t want to pay for more than they need or worry about bill shock. Our incredible value comes from the combination of our nationwide 4G network, exceptional device portfolio and affordable plans that offer unlimited data access without overages.

Although the prices of all the available plans were not available to view on the press release, T-Mobile did quote one such example of a typical plan. A Value family plan with unlimited talk time, unlimited texts, and 2GB of high speed data is available for $49.99 per month, per line, based on two lines being bought. Of course, this doesn't include the additional purchase of smartphones with the plan, but it is still a fairly good deal. It will certainly be interesting to see how much the 5GB and 10GB high speed plans cost, as these will be sure to tempt power users away from other networks, especially if T-Mobile has good 4G reception in their area.
