Think that LTE tariffs are too high? Well, US Cellular is now offering unlimited LTE for $40/month. Unbelievable right? But this is just a promo offer and is only valid for the holidays. And if you want to add tethering you will have to pay an additional $20. US Cellular is not stopping at unlimited LTE, they are also offering a rebate of $100 on a purchase of Samsung galaxy S3 and Huawei Ascend Y. Also on offer is a free 4G LTE Samsung SCH-LC11 hotspot on purchase of a smartphone or tablet. One can check out the offers at the official site of US Cellular. But do check the fine print while purchasing.
