Thanks a lot for your contribution Alex! We will update your fix to the main content of the article and see if it helps others!
I have iOS 14.7.1 on iPhone 11 and when Wi Fi is turned off or I am travelling I click on bank Icon and get Something went wrong a server with the specified hostname sound not be found for one and No Internet Connection you’ll need to be connected to the internet to continue. Also my Yahoo emails don’t update and I already removed from the phone then re-intalled.
Very frustrating in that I can’t go back to the previous iOS
Does a restart temporarily fix it?
I have an issue after update to iOS14.7.1 on iPhone SE 2020. All programs which required internet stopped to work and could not use cellular data. For troubleshooting, I performed all possible actions that I was able to find.
– restart iPhone
– turn on/off cellular data
– take out/put in sim card. Replace sim card. Use another person sim card. Use your sim card on different phone. My sim card was fine, my iPhone was not fine with any other sim cards
– multiple changes in settings
– erase all network settings
– factory resetting iPhone and restore it from backup
– 2-3 times reinstalled iOS
– hours on phone with cellular provider with diagnostics
– I’ve changed a cellular provider, but had the same issue with a new one
– full copy on my iPhone with all my settings on my friend’s iPnone had no bugs, but my iPhone, completely erased and restored using exactly the same backup, reproduced this issue
So what worked in my case. 1) Register online and download iOS15 beta7. Nope, it does not resolve an issue, it would be too easy. 2) Go to settings -> general -> VPN & Device managements. 3) manually delete ALL configuration profiles except for iOS 15 4) voila, I have all programs able to use cellular data again.
This knowledge costed me >$100 and >2 weeks: changed cellular provider, bought software for custom backup and restore, lost already paid new cellular plan with a previous provider… I hope someone who has a similar nightmare after iOS update to 14.7.1 can use my advice to stop it my lower cost. Update to 15 beta, ensure that now you can see all configuration profiles in “VPN & Device management”, and delete all of them except for “iOS15”.
Thanks for sharing this extensive feedback. Can you follow up please with a clarifications: did you have any other profiles installed on your iPhone before downloading the iOS 15 beta profile?
I think I found the fix! Here is what worked to restore service and stop the daily intermittent SIM failure errors after the 14.7.1 update to my XS and my wife’s 12. We are using eSIMs on AT&T. I removed our plans using Settings>General>Reset>Remove all cellular plans. Then I added them back using the QR codes on our carrier’s eSIM setup cards. This appears to have completely resolved our problem.
Before I tried this we had driven ourselves crazy rebooting, erasing cache and network settings, turning airplane mode on and off, wifi on and off, near and away from our wifi network, gotten a new physical SIM card for my wife’s phone, turned roaming and wifi calling on and off. Nothing worked until I removed all cellular plans.
Thanks a lot for sharing this Heath. I will update your troubleshooting tip in the main content of the article.
