Mobile data disabled after Android 15 & one UI 7.0 update

[Lokesh_06]

Hi, 

Today (28th june 2025) morning I've installed latest software update of android 15 & one UI 7.0 since then my mobile data got disconnected and settings for mobile network is completely greyed out. 

I've tried all type of reset including factory reset but nothing made it work. Im able to make call or receive call from the same device and also data is working fine on this SIM from other device.

Can you upload the ss of the greyed settings

Have you set any DNS server?

[Lokesh_06]

I haven't changed anything and it's default how it was as attached

[armlinker4639]

Upload the ss of your SIM Manager settings

Please find it attached ... I've a suspect on airplane mode which is half white but im able to enable and disable make calls but that icon colour is not fully blacked like others... see highlighted in attached

That explains the problem.
Actually the software maybe got stuck while turning OFF Airplane Mode

Try clicking it again till it becomes black again

I did it as many times as possible and it is turned off which is why I was able to make calls and receive calls... i shared it as suspect because it is half greyed which doesn't mean it is turned on.. if so I can't use wifi too how im sending this message out... isn't it ?
