15.2 ios update is causing me to lose cellular and data service.

Hi f.rios75,

We see your'e running into issues with your cellular data after updating to iOS 15.2.

To clarify, what specifically happened? Are you unable to use the internet or cellular data at all post upgrade, or does it seem to be slower, intermittent, etc?

If you specifically see No Service or Searching on your iPhone, take a look over the tips below:

• If you see No Service or Searching on your iPhone or iPad

Otherwise, let us know some more details of what specifically is happening, and we'll continue from there.

Cheers!

f.rios75,

Thanks for clarifying.

We'd recommend working through the steps in article from our previous post if you have not already, as they'll resolve a number of issues with intermittent connectivity.

If you notice the issue persists, reach out to your carrier to confirm if there's any updates or changes to their network on their end. Should they find nothing amiss, contact Apple Support directly for additional assistance.

• Get Support

Take care.

Same thing is happening to me. This is the device information.

Carrier: Spectrum Mobile

Device: iphone 7

Model: A1660 (found on back of phone)

iOS Version: 15.2

Here's the history.

• Around Dec. 14/15 my cellular stopped working (ie showed "No Service" in the upper left corner or "Searching"
• Called Spectrum Dec. 17 and tech support said others were having the same issue. We did the following (reset Network, phone reboot, removed sim card, soft reset, turn off wifi and cellular for 30+ seconds) and none of this worked. Basically I did everything except a full factor reset of the phone. I happened to have an extra sim card that i never used so we tried this new sim card. This fixed the issue...for about a week.
• Cellular worked from Dec. 17 to Dec. 24 then same issues
• Called spectrum again on Dec. 26 and tech support again confirmed other customers were having the same issue. We swapped back to the original sim card...it didn't fix the issue this time.
• Called Apple Dec. 26 and tech support said other were having the same issue. I was put on hold and then I think the tech support person accidentally hung up on me so I posted this on here.

Not sure what to do next with this. It seems like it's related to the iOS 15.1 update and after because i had the issue before I updated to iOS 15.2. I know this because I got a message that said I needed to update my iOS in order for cellular to work. So I performed the update to 15.2, it didn't fix the cellular issue and i'm still getting the same message that I need to update my iOS for cellular to work. Frustrating...

My iPhone 7 is not connecting to cellular network after 15.2 update

Im in the UK and im having the same issue on my iPhone 11 and my wife's iPhone 12. We are with EE(UK). We used to get 3 bars of signal but since the iOS update we now receive no signal at all. My neighbour on the same network and android phone has full signal.

This is frustrating as I take calls at home for work and I don't want to rely on wifi calling. Come on Apple. Sort this out!

i am also having same issue while upgrade to 15.02 in iphone7 cellular service is not working .now showing no service in cellular information.

Also, have tried a lot of techniques from google but still not working . why upgrade is having such issue.

I’m having this issue too. I’ve tried everything online with it occasionally having temporary success. However then it may work for 15 mins one time , then a few hours the next.

it makes me think the update was designed to do this . Anyone find a solution?

im going to see if I can downgrade to previous iOS next

I called Apple tech support again and they made an appointment for me at the nearest Apple store tomorrow so they could look at my phone. They are thinking the same thing that deggie just posted. Thanks for the link deggie.

At the store they said the problem was due to an antenna connection failure that is common with certain iphone 7 builds. My phone falls into this group. If the antenna fails within 4 years of the purchase date, they will repair the phone for free. If not, they don't. My phone was past 4 years. Assuming they were correct (they didn't open the phone to confirm the antenna broke) then the update had nothing to do with the loss of cellular service.

As for why the phone worked after switching the sim card, maybe the action of removing and reinstalling the sim card moved the circuit board around enough to temporarily fix the antenna connection.

In any case, I bought a new phone, installed the original sim card, and went through the setup process. Part of that process downloads the latest iOS, 15.2. The cellular works again without any issues which means the sim card was never the problem.

I'm having this problem as well, on my iPhone 11 with 15.2. It happens two or three times a week, usually when I'm out driving around and using CarPlay. I'm not sure if using CarPlay is having any effect or not. But, I usually can't get cellular service back until I fully shut down my iPhone and wait awhile before rebooting.

On a side note, once my cellular service is back, my CarPlay favorites and settings are wiped out.

I am experiencing similar issue after 15.2 upgrade. I have taken the troubleshooting a bit further. It seems I lose cellular connection after leaving Wi-Fi connection. My guess at this point is there is some bug that is not letting it switch from Wi-Fi to a cellular signal for data. The symbols change in top right but in action it does not. What leads me to believe this is when it seems I have no cellular connection i turnoff Wi-Fi and put in airplane mode for 10-15 seconds, then turn both back on. Issue is resolved and works like normal. Maybe apple can look Into this issue.

I’ve been experiencing general network issues since the 15.2 update. My Bluetooth, Wi-Fi, hotspot and mobile data are all messed up. My biggest concern is why apple wouldn’t admit the issue or release an update to fix it.

Yes since installing this update I've been having connectivity issues where as my other lines that didnt update yet are perfectly fine. This is really frustrating Apple. Since I also subscribe to Apple music and .i can’t even use it on my commute. Apple needs to compensate people or at least fix this ASAP!

I have been having the same issue since I upgraded to 15.2 but the work phone I have that didn't update is working fine. I thought 15.3 would fix it but it didn't. The issue is still occurring and becoming irritating that my phone isn't useful and that it has gone on for so long.
