I recently switched to Sprint from Verizon so my fiancée and I could be on the same plan and save money for our wedding. I got the iPhone 5s. The data speeds weren't as terrible as I had read where I live in my LTE Sprint area. Then I come home to visit my family. They live in an US Cellular LTE area. I have always picked it up no problem whenever I had Verizon. With Sprint however I don't pick up either 3G or LTE. I've been on the phone with them many times and nothing fixes it, and they have absolutely no idea what they're talking about Any suggestions?
