Hi, my iPhone7 automatically updated to the 12.4.1.
It keeps says 'Cellular Update Failed' - Your iPhone cannot make and receive calls and access cellular data until it has been updated.
In software update it says its up to date.
Not sure what to do?
iPhone 7
There are two major Updates in an iPhone / iPad:
How to Update Carrier Settings
You can manually check for and install a carrier settings update with these steps: Make sure your device is connected to a Wi-Fi or cellular network. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.

How to update iOS
Go to Settings > General > Software Update > Automatic Updates, then turn off AutomaticUpdates. At any time, you can check for and install software updates. Go to Settings > General > Software Update. The screen shows the currently installed version of iOS and whether an update is available.

I am having the problem too. I go into Settings>General>About and it never tells me an update is available yet a few hours later it keeps telling me a cellular update has failed. The only way to make my iPhone 7 operational is to keep turning it on and off and that only sometimes works. Is this a bug in 12.4.1 and will be resolved in iOS 13? I'm tired of having to babysit this phone. Please help.
Mine is doing the same... immediately after the 12.4.1 update my iphone 7 started with the “carrier update fail” messages. I’ve updated the carrier settings and reset phone numerous times and nothing seems to work permanently. Please help, this is annoying and the phone is unusable when away from WiFi.
I even joined the iOS beta program to upgrade to 13.1 beta 3. The problem is still not solved. I had to cave and preorder one of the new iPhones. I guess that’s one sure way to make us upgrade! Sabotage the old ones. 😔
This is getting absolutely ridiculous with the Iphone7.
I had an issue similar in Feb where it said the SIM card wouldnt work, and bricked my phone. For those of us who NEED a phone due to work, that meant driving TWO AND A HALF HOURS each way to an apple store, taking a **** full day off work to address this.
Now, six months later, I'm in the same boat. Saying cellular data didnt work. I tried resetting network settings, updated the carrier and IOS, and now did a DFU reset.. and HAVE ANOTHER BRICK. Why in the world I'm spending this much money on something that paralyzes me every six months is incredible.
I finally called Apple and they said my iPhone7 was one of the ones that were recalled and they gave me a loaner phone while they are fixing it. Hopefully everything goes well and I get this resolved because I refuse to let this situation force me into an upgrade.
Check to see if your iPhone 7 is among these eligible for the recall. I found out mine was:
Mine is doing the same since the update. I reset carrier settings and have the most recent 12.4.1.
