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 🤠

Lost cell service on iPhone SE after updating to ios 17.4.1 two days ago. I tried the turn off wi-fi turn on airplane mode method and it didnt work. Had to factory reset, but made sure I chose the retain eSIM option before shutting down. Started back up with my eSIM carrier and all is now better in my life!


What makes my story even more harrowing is that I just lost my iPhone 12 Promax about a week ago due to a software download and had nothing but hassles from Apple about resetting my password to transfer my data to my new Apple iPhone. Then to lose two more days due to their glitch is just unconscionable.


Was thinking about getting the iPhone 15 Promax, but after seeing they are vulnerable to Apple's inside attacks, I'm not so sure.


Y'all at Apple need to remember it is we, your customers and shareholders that you ultimately answer to. I'm sure Steve Jobs would be frowning upon the direction his company has taken in recent years.

So I work at bestbuy and my geek said agent said to if you have a Mac go to finder on your laptop/desktop put phone in recovery mode then force the iOS 17 update if you have regular pc you would instead you use iTunes and do same thing if it doesn’t work back up your phone then reset your phone it shouldn’t prompt the default iso as 17 hope this helps.
