T-Mobile is attempting to fend off its competitors again. This time, they are making their "unlimited" plan more attractive by raising the deprioritization limit by 2GB. Now, you'll have to exceed 30GB of usage before your speed is reduced. This gives you about 8GB more of freedom than the competition; Verizon and Sprint will start throttling you at 22GB and 23GB respectively. Verizon Wireless and AT&T may slow down users in areas of network congestion after they reach 22GB in a single month; Sprint allows 1GB extra at 23GB.
