US Cellular

U.S. Cellular is hoping to compel some users to head over to its network by offering $300 to families that bring along two or more lines and activate a smartphone. The incentive comes in the form of a prepaid MasterCard debit card, which is probably better than other ways they could've done it, although we may have preferred to have it put on your bill as a credit for service.

The promotion U.S. Cellular is running right now also includes several other incentives. New and existing customers living in LTE markets can take advantage of the carrier's unlimited data plans for $40 per month. The carrier says that 58-percent of its customers currently have LTE coverage, and that number will be almost 90-percent by the end of 2013. There are a few device discounts going on currently as well, with the Huawei Ascend Y for $0.01 and the Samsung Galaxy S III (with LTE) for $149.99.

If you've been thinking about moving to U.S. Cellular, now may be the time. These smaller and regional carriers tend to put together some pretty decent incentive packages to get new customers in.
