Cellular Data not working after IOS 27 update

Hi guys! Are you experiencing cellular data issues (I use Ting) after the iOS 27 update? Since the update, cellular data has been going in and out and not working at all. I contacted Ting, who told me they have been getting lots of complaints about the cellular data since people have updated to the new IOS, and I'll need to wait for a new update. I was hoping there was a quick fix someone would know about! I use a 17e. Thanks!

This procedure from Ting Mobile worked to help get back cellular data and WiFi calling on an iPhone 17e using the Verizon network:

It sounds like a carrier issue. Carriers issue much of the software/firmware for cellular calling and data. In my experience, these issues can generally be resolved by the carrier reprovisioning the eSIM or SIM. I've personally not had good luck with Over the Air (OTA) provisioning and now I just head to my carrier's service center when I have an issue. Good luck.

They told me to go to settings > cellular > cellular data network, and enter VZWINTERNET into the cellular data APN, but told me its a temporary fix they've been giving people. Hope that helps!

Please contact your carrier. Carriers provide a lot of the software for the modem. You can check if your carrier has done an OTA update by going to this path,

iPhone > Settings > General > About > if an update is available a notification will appear in a few seconds. Follow the on screen instructions.

No fix here, just information. I spoke with a Ting-Verizon associate this morning who told me that cellular data and Wi-Fi calling problems due to iOS 27 update are being worked on by Ting and Apple together. I will get an email update from Ting when there is a solution. In the mean time I would advise downloading regional maps for navigation.

Hi, contact your carrier’s support team and see if they have a fix for your specific issue.

I’m having the same issues on an iPhone 15 pro. Oddly enough that my other iPhone 17 pro max has no issues. Also with Ting and waited a hour to talk to someone yesterday. Did all the resets, even tried switching eSIM and still didn’t work. Real frustrating.

I use tmobile on my 13, my hubby has ATT on his 17 and within 24 hours of the update neither of us can connect to our carriers. Contacted carriers first and they found no problems so it has to be an apple/ IOS issue.

Yes, it’ll help Ting customers until Ting fixes the issue and sends the fix to Apple.

Did they mention anything about the settings for MMS or personal hotspot?

No, they did not. They just gave me the cellular data APN and told me to wait for the IOS to update

Ting told me Personal Hotspot is grayed due also to the cellular data problem.

Has anyone got a fix? I’ve called and emailed several times and keep hearing they’re working on it. I’m about to just change carriers.
