Chosen Solution

After iPhone 5s dropped on floor, small crack on display around the lightning connector (and kind of close to antenna). No service / searching… / or 1 bar Edge connection that’s unusable (can’t make calls). Wifi works fine and everything else seems fine. Is the iFixit store part “iPhone 5s/SE Cellular Antenna$14.99” what I should be ordering to fix this? Seems obvious kind of, but then again I just can’t imagine a drop would damage the antenna, it seems pretty securely in place?

If the antenna appears damaged in any way, shape, or form then that is most likely your problem. The required antenna is provided below and also with a guide on how to replace it. iPhone 5s Bluetooth and Wi-Fi Antenna Replacement iPhone 5s/SE (1st Gen) Bluetooth and Wi-Fi Antenna
