Hi everyone,
does anyone going through dual sim network issues after iOS 27 update. Everything was working perfectly before update but when I updated my phone to iOS 27 days ago straight away I started getting network problems. I have force restarted the phone, reset the network settings and did everything possible but nothing works.
iPhone 14 Pro, iOS 27
Same here on my side in germany.
I already change both E-Sims with no sucsess at all.
When both lines are active no mobile date can be send / recieved.
If one line is switched off mobile datas are available.
I got no solution for this issue instead of waiting for an IOS fix.
I am facing the same issue but i ahave iphona 13 with only 1 sim card but i couldn’t solve the problem i used everything
This could easily be a bug introduced in the last upgrade. A portion of the modem firmware and software is written by the carriers. There are already community members posting about fixes from their carriers.
I personally faced a similar issue last year with my iPhone 17 Pro Max and AT&T. They tried an OTA reprovisioning and it repeatedly failed. I went into an AT&T store and issue resolved in about 10 minutes.
You can check for any OTA updates by following this path,
iPhone > Settings > General > About > if an update is available from the carrier a notification will appear
Typically the next update from Apple is 4 to 6 weeks after the initial release. I’d talk to my carrier.
