Following the suits of Verizon, T-Mobile, and AT&T, the US Cellular will soon be announcing that it will be reducing the prices of data plans to make them more competitive for both existing and new customers.
This is not a promotional change, so if had a USD 40 monthly plan, you only had 300 MB of shared data but now you will have 1 gigabytes of data to play with. In other words, you will be able to enjoy three times bandwidth at no extra cost.
