Similar network issue after installing March update on Fold 4, but for me no Wi-Fi!
Reset and safe mode doesn't help

That's even worst, no Internet on it.

Is it a middle east model. I think you should take it to a service center.

Yes, that's the reply I got from Samsung rep over chat. As per other threads, the service center will install a new OS image with the previous update

It seems only for some, my wife and colleague has the same phone, all taken together, but they don't have any issues even after the updates

I backed up my data and did a factory reset. All seems clear now. But ain't gonna do any software update for a while. 😜

Here are some troubleshooting steps you can try to resolve the issue:

1. Check Mobile Data Settings: Go to Settings > Connections > Mobile networks > Mobile data to ensure that mobile data is enabled. Also, check if the correct SIM card is selected for mobile data usage.

2. Restart Your Device

3. Make sure that both SIM cards are properly inserted into the device and that they are not damaged. You can try removing and reinserting the SIM cards to ensure a proper connection.

4. Check APN Settings: Access Point Name settings are required for mobile data to work. Go to Settings > Connections > Mobile networks > Access Point Names and verify that the correct APN settings are configured for your network provider.

5. Reset Network Settings: Go to Settings > General management > Reset > Reset network settings. Note that this will reset Wi-Fi, Bluetooth, and other network settings, so you may need to reconfigure them afterward.

6. Check if there are any pending software updates for your device. Sometimes, software updates include bug fixes that can resolve issues with connectivity.
