Turning Off Wi-Fi Calling and Voice LTE Might Fix the Problem

Some individuals have reported that turning off Wi-Fi calling and Voice LTE allowed them to do a cellular update. This is an inelegant solution, but it’s fine as a temporary fix.

However, do keep in mind that not all carriers support these two functions, so this isn’t going to work for everyone.

  1. Open Settings, and then tap Cellular.
  2. Scroll down to Wi-FiCalling.
  3. Toggle off the switch next to it from the right side to the left. It should go from green to clear if you’ve done it successfully.
  4. Next, go to Settings, then Cellular.
  5. Tap Cellular Data Options.
  6. Tap Enable LTE, then Data Only. This will turn off the Voice LTE feature. The Data Only option should have a blue checkmark.
