Cellular service UNAVAILABLE since updating to ios17.0.3

I recently updated my XR to 17.4.1 and ever since my cellular won’t work at all, it’s completely fine when on my home internet but the second I step away from my house nothing works and it just keeps saying that it cannot connect to cellular data?

My iPhone 12 updated overnight to 17.4.1 and now I’ve lost all cellular data. Only works on Wi-Fi. I’ve seen other people on here. Have problems all the way back in February. What did anyone do to fix it? Do I have to take it into the store?

After updating my device to ios 17.3.1 i have lost of network issues please fix this problem.

So my phone automatically updated, and it broke my cellular to the point that it is now my problem, and I have to contact the carrier and re-set everything? This is ridiculous and is taking a lot of time. Will there be a patch soon to fix the update?

I had updated my ios to 17.4.1 now my cellular signal is completely gone.

I tried everything from:

1. inserting and removing my nano sim
2. Rebooting my phone
3. resetting my network settings
4. resetting my settings to factory default

Can anybody please help

me?

after updating my iphone xr to ios 17.4 my 4g is not working anymore it doesnt show up and it doesnt work pls fix this problem

my phone updated this also 17.4.1 update and I am also not able to use my cellular data !! Huge inconvenience! Hope this is resolved soon !!

Had this same exact problem and was able to fix it with this:

1. Cellular Data off
2. Wifi off
3. Airplane mode on
4. Power off the device
5. Wait for 8 minutes before you power it on
6. Airplane mode off

As an iPhone 15 Plus user, I have been experiencing this error since iOS 17, and it's very annoying that I have to switch my phone to airplane mode several times because there is simply no data connection, even though the phone is connected to the service provider.

Same issue but for ios 17.4.1

Having the same issue with my iPhone 12 Pro! After updating to 17.4.1 Any help would be greatly appreciated.

Did you manage any fix? I have the same issue.

I have an IPhone 12, and I had the same problem. I restarted my phone and data afterwards data was working, again.

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:

• iPhone wireless carriers
• iPad wireless carriers

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

Best of luck,
