Cellular Data Not Working On iPhone? Here's The Fix!

David and David explain what to do when Cellular Data is not working on your iPhone. This can be a tricky issue to troubleshoot, but the good news is that you can probably fix the problem at home. The first step is to figure out whether your iPhone or wireless carrier is the cause of the problem.

We'll start by troubleshooting simple iPhone software problems, then minor issues with your carrier. If Cellular Data still won't work, we'll discuss some more in-depth troubleshooting steps.

You guys are the greatest. My wife’s and my iPhone both went down at the same time. Could not make or receive calls. Watched this video, did the reset thing, just carrier portion, and, boom we had service back. Weird that both of our phones went down. We are on my sons plan and his other phones were fine! Thank you for the fix.

None of these worked for me turned my VPN off and magically everything loaded and refreshed etc....this was AFTER I reset netowrk settings, ejected the SIM, factory reset my phone entirely and then threw it against a wall 15x.

You guys saved the day for me as well. I noticed that I was getting "some" data, but not all data. I would be able to get mail, but using Uber, or using my browser was a bridge too far. I was stuck at a doctor's office for about an hour until someone gave me a wifi password. Anyhow, the carrier profiles was what worked for me. Once I deleted the one for cellular service the internet just started working like magic. Many thanks!

[Zirofol]

Thank you so much for this! The extra configuration profile was incredibly sneaky

[danielpearson]

Just wanna say.. YOU GUYS ARE AWESOME!! You’re video just solved a month old problem with a easy fix. Thank you!!!

[rosylives]

Mine was a VPN problem created by blockada, an ad blocker I installed a few month ago. You video helped me identify the issue, than you!

[sergiogarcia]

Thank you! Deleting the profile solved my problem! I spent HOURS over several days with tech support! They had me do everything you did except for the profile part. It was so easy once you showed it!

[dariareader]

Thanks so much! I just came back from the UK and my data wasn’t working. Spent hours on the phone with Verizon without a solution. Your tip #6 saved me! I just needed to delete the UK data profile. Super helpful!!

[jrswon]

I was on call with t mobile tech support for an hour but then I decided to watch this video. In less than 1 minute my phone is working perfectly fine again. Fastest sub in my life :)

[kellycuckoo]

The technology department in Verizon were no where near as helpful as you both. Thank you so much!

For me, physical SIM card cellular data stopped working with the iPad Pro 11 after updated to iOS 15.1. None of the mentioned methods worked, short from going to Apple or the phone network supplier. There was no profile to be deleted. The Cellular Data screen only shows a few Network names that is not local to here along with "Other..." for some network provider settings with provision to scan network provider QR code presumably for setting up the eSIM, as if the physical SIM wasn't even in the iPad. I have checked the old SIM cellular data still works on my other mobile devices. So no, taking the SIM out and put back into the iPad did not work either.

What actually worked was I tried putting another SIM card which also has cellular data activated. It worked with the new SIM right away! And when I put back in the old SIM the iPad Pro asked for a Network Update soon as I put the SIM into the iPad, and cellular data works after the update! Other than that, even resetting Network Settings didn't. Go figure.

I had data roaming turned off for some reason, and yay turning it on resolved my problems ! I try to use wifi when possible but in those rare times, cellular is needed thanks guys!

[imagoatgaming]

I have xfinity mobile which is covered by Verizon. Should I still have data roaming on??. Also should I keep using lte instead of 5g auto

[nenghanihandayanipc]

Thank you sooo much for the tips. I’ve been struggling to solve my connection issues and thanks to your video save me during my stay abroad 🙆🏻‍♀️

[karencastoldi]

Wow. Love you guys. I discovered you today in your video on saving data usage on your phone. I was able to do everything but turn off my Wifi Assist. I saw a random comment in my search suggesting turning on cellular data. So, I searched for a youtube video. Because I now subscribe to you, this video came up. Easy peasy ( Im 62 ) Sure enough, now my Wifi Assist is able to be turned off. Thanks again!!!

I have a n iphone 13 pro max, not upgraded yet out of fear of battery issues with new software, what do you two recommend upgrade or not?

[anxgelzz]

Will resetting all settings on my iPhone erase everything on it? I’ve had a cellular data problem for a long time, and now it’s even worst because I can no longer receive phone calls or text messages. I also have an IPhone 7, and it will not update or show no update for me much of anymore, and even if there was an update it will not let me update my phone.

[stacymai]

You guys have saved the day again. You’ve prevented many mini-meltdowns for me when my phone decides to go wonky. I always go straight to your channel now when I have a question or problem. Thank You!!!

[anthonycerami]

Thank you ! got my cellular data working again thanks to you guys!

[lilianamartinez]

It seems like #6 finally worked for me. I had tried everything (restarting, airplane mode off/on, reset network settings, got a new iphone REALLY - i had an old one upgraded to iphone13) and #6 is the only one that has seemed to work so thank you thank you
