T-Mobile's new contract-free value plans have just gone live. All of the new plans will have unlimited calling and unlimited texting included. The cheapest plan available is the $50 unlimited talk, text, and 500MB of data plan. If you want to increase your data limit, you can do so for an accumulative $10 charge. So for the 2GB plan, you'll have to pay $60, 4GB you'll have to pay $70, etc. After you reach your data limit, your data will be throttled to 2G speeds. All of the tiered data plans come with free Mobile Hotspot, so you can tether your phone to your laptop or PC.
