Lost cellular data after iOS 18.6.2 update

Hello -

Our cellular provider is TMobile. We have 3 phones on our account. We recently had this exact same issue on all three phones. I troubleshooted all remedies found from google searches. (That is actually how I found your question here.) I finally called TMobile and somehow "gremlins" adjusted our account to be WITHOUT internet provided. Holy smokes. That's crazy....right? Anyhow the fix to our issue was for TMobile to "fix" the account and then they had to provide new eSIMs for all three phones. What a hassle. 3 hours later all cellular data was restored.

Two separate phones with the same carrier(?)

Did you call your carrier/cell provider and see whats up? They can re-provision your device(s) from their end.

report back your success or failure

No matter how annoyed you are, the only place that can fix cellular connectivity problems is your carrier. What did they say when you called them?

The one possible exception is if you have a 3rd party VPN installed, even if you are not using it. If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN, then restart your device. Don't just turn it off; delete the profile. If that fixes it, you can try reinstalling VPN, but probably shouldn't.

Have you tried the trick of contacting your carrier?

Asking if they have a local outage?

Are you aware that on August 30 Verizon had a nationwide outage that affected 18,000 phones across the country?

You can check up on them yourself→Down Detector - Crowdsourced Outage Check

my Carrier tried multiple things including giving me an eSIM which did not work. After three hours on the phone with them and multiple network resets, I was able to make and receive calls although I had to turn on and off airplane mode to get a signal a few times. I was told to go to a store and get a new SIM card. The next morning I found an update waiting and guess what? Now it’s all good again. I picked up the new SIM just in case but it was clearly the update that caused the problem.

Thanks for following up and reporting how it was fixed.

I’m having the issues for a week. No reports of service down. Getting very annoyed

Same issue. Updated yesterday and now no Cellular Data. No outages at provider. I’m in Canada.
