iOS 18 beta 4 loss of network connection

Hello,

I installed iOS 18 beta 4 today and since then my phone loses network connection all the time. Im unable to use my phone, make phone calls, use 5g etc. Please help!

I restored my phone to 17.5.1 via itunes but I was unable to restore my iCloud backup without installing iOS 18 beta 4 again.

How can I restore my backup without installing 18 beta 4 ? Now my phone is useless....

Same issue here, downgrade to 17.6 didn’t help!

Is this fixed in the new beta five that came out today? I downgraded using one of the IPS W files for beta three which I knew didn’t have the network issue for me. If you aren’t aware of this option, just google iOS 18, beta IPSW and there are some good instructions. I recommend the configurator app to load this as I ran into an error just using the regular finder restore. I think I used this site but there are a couple https://ipsw.dev/download/iPhone16,1/22A5307i

With iOS 18.0 Beta 5 (22A5326f) no network lost problems with my iPhone 15 Pro Max in germany

Same for me constantly dropping connections on the move in the UK. I have EE for primary line and alternate between 3 and Vodafone for secondary line and drops 100's of times a day rendering the phone almost inoperable. I wish I had never signed up for this developer beta and just waited for the public release. Lack of patience resulting in me nearly throwing my phone out of the window. Avoid!!

Same issue from Turkey

Beta 5 solved it for me as well :)

Same here on PB 3 ..

iPhone 15 Pro, on the 🇬🇧 Smarty Network.

Can receive calls ok, but no data service when I want to receive texts or emails. Works ok on WiFi.

No problems on any of the previous Public Betas

Sadly same issue form me (Poland, Orange). Using iPhone 15pro, setting to just LTE doesn‘t solve the issues, cannot install 18 beta 5 because installed 18.1 which also doesn’t fix the problem - which I hoped it would.

It seems that the issue is outside the US?

The stacks files in analytics states a baseband crash detected at random. the stacks files shows up when this error occurs.

I sent feedback but investigation was completed with the status that they are unable to diagnose this issue with current information. I attached 2 new stacks files with this error. Dunno if they will be checked.

Still no resolution on this? Phone is literally useless unless I’m connected to WiFi.

Hey Guys,

I also have the same problem with Orange network in Poland my iOS update is 18.1. i have the same situation not regularly disconnects me from Orange network transmitters

please help how to fix it :)

I got the same issue, phone is barely usable with eSIM 18.1 and constant cellular dropouts!

Same issue here, and I thought it was the network problem but is the beta

Same issue in Italy on TIM

They seem to have fixed it with the new beta update, i used to have it all the time while i was outside but after i updated my phone yesterday, i didn't have any signal loss

I can only downloaded to Beta 3 up to date, you guys have Beta 5 to fix the problem?

I installed the beta yesterday sep 20th, And my connection is always on edge, I am able to use wifi, but no connection once I am not with wifi… I have an Iphone 15…

Having the same issue on iOS18 beta 4. I’m on the iPhone 16 pro max, and every few minutes my WiFi connection just drops off. If i turn off WiFi and turn it back on it’ll sometime work, currently my WiFi is off and I’m on 5G.

I am facing the same issue even after updating to the stable release of iOS 18 on iPhone 13 in India.
