How do I install software updates on iPhone 17 Pro Max using cellular data instead of Wi-Fi?

verizon hasn’t come to install WiFi yet in my home but I have software updates that I installed and every time I installed one, after my phone restarted I got an SOS in the top right corner of my phone in the color yellow which means no service but I do have unlimited cellular data with my Verizon simplicity plan so why can’t I install software updates or any updates for that matter using just my cellular data?

Hi there


Please try this


  1. Open Settings on your iPhone.
  2. Tap Cellular (or Mobile Data).
  3. Select your active cellular line/plan.
  4. Tap Cellular Data Options.
  5. Tap Data Mode and select Allow More Data on 5G. (This allows iOS to use cellular data for heavy tasks like software updates).
  6. Go back to Settings > General > Software Update and tap Update Now.
