Cellular service UNAVAILABLE since updating to ios17.0.3

I've updated my ios to iOS 17.0.3, and since then I do not have ANY Cellular Service. I've been to the Vodacom Shop, and they said I should send it in for repairs. Is there any solution rather than that, cause I need my phone to work with

iPhone 11, iOS 17

Sorry to hear you are having this issue.

I would try the following:


Check for a Carrier Settings update

To manually check for and install a carrier settings update:

  1. Make sure that your device is connected to a Wi-Fi or cellular network.
  2. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.
  3. To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier.

If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.


Turn your cellular line off and back on

Go to Settings > Cellular and check to see if your cellular line is turned on. If your cellular line is off, turn it back on. Then check to see if you have service.

If you don't see your cellular line in Settings > Cellular, you should set up an eSIM or insert a physical SIM card. If you're using a physical SIM card, remove the SIM card and put it back in.

If your SIM card is damaged, doesn't fit in the SIM tray, or you transferred your physical SIM card from another device, ask your carrier for a new SIM card. 

Learn more about removing your iPhone SIM card or iPad SIM card.


Reset your Network Settings

Go to Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before.


Contact your carrier

Issues with your carrier or account might affect your service. Contact your carrier to:

  • Verify that your account is active and in good standing.
  • Make sure that there are no outages in your area.
  • Check that your device isn't blocked from receiving cellular services and is set up with the right data plan.

Only your wireless carrier can access and manage details about your account:


If the issue still persists even after contacting your carrier, contact Apple Support.


Best of luck,

Bryce 🤠

My phone 13 updated last night to iOS 17.4.1. I don't have any cell service at all. I spoke with my phone provider XFinity all morning and they cant see anything on their end that explains the issue. They say Im connected on their end but there are no bars on my phone that shows I have service. I have access to my wifi. But I cannot receive or make calls or texts on my phone. This is an extremely HIGH inconvenience as I work from home and need access to my phone 24/7 !!! please let me know if any one has a real solid solution to fix this! I have tried the sim card method, I have tried turning it on airplane mode and turning it back on... and nothing is working.

updated to 17.4.1 - same issue

PLUS i'm on a call, sitting in a stationary place and my phone keeps flipping from 5G to 5G+ throughout the entire call, causing me to cut in and out and the person on the other end can barely make out what I'm saying.


Is apple support even reading this thread anymore? Is there an update to fix this bug? I can't keep turning my phone on and off 7 times a day, or going to airplane mode. I have work to complete, as I'm sure many others do, and I cant get it done when my flippin phone doesn't work!

Have the exact same problem ..since the update cellular data is wiped out , I tried everything nothing works..really inconvenient with my work..if it doesn’t get fixed soon by an update, for me apple is history .its ok to have issues every now and then as long as you take responsibility for them and help solve them.
