iOS 9.3 didn't only make it tough for a lot of users to open web links, it also rendered some Sprint subscribers unable to connect to the carrier's LTE network. According to the social media posts by some of the carrier's iPhone 6s and 6s Plus users in Southern California, they started grappling with the technical issue after updating their mobile OS. While Sprint hasn't issued a fix yet, it says its "network team is aggressively working to resolve the issue." The company adds that it "expects to have a solution in place as quickly as possible."
