S21 FE mobile data issue

Hello,

Since the May security update, my S21 FE has been unable to use mobile data from SIM1.

 

To clarify, i use both SIM card slots on my phone, and the mobile data works fine on SIM2

I have tried:

Restarting the phone

Turning airplane mode on and off

Changing the mobile data from SIM1 to SIM2 and back

 

There's no problem with the SIM or the network, since when i put it in my S9 the data works fine. 

 

Any suggestions?

I actually stumbled into the solution myself. I checked my provider's  settings for the network and then went to compare them with my phone's. Apparently the newest update removes the "default" type from the "APN type" setting on the network settings, causing the data connection not to work!

All i had to do was type "default" back into the APN types for the network.

Very strange and random, probably a bug that slipped through the update.

I am facing the same issue. The VI sim works normal on my other devices and I have not observed any issues but with this S21 FE there are problems.

When inserting the VI sim, the battery is draining fast also there is not showing any network.

So, I went to VI center and exchanged the sim card with a new one but that is also not working in this Samsung galaxy S21 FE but the same sim card is working fine in other devices.

Even I also did all the troubleshooting steps mentioned like network reset, safe mode, aeroplane mode, and at the end I did factory reset but still I am facing the same issue. My VI sim card is not at all working in this device. I have purchased this phone just 2 weeks ago.

Can someone please provide me any genuine solution?

Since the May security update, my Samsung Galaxy S21 FE is unable to use mobile data from SIM1, while SIM2 works fine. I've attempted basic troubleshooting such as restarting the phone, toggling airplane mode, and switching data between SIM1 and SIM2. The SIM and network are not at fault, as they function well in another device. Suggestions include checking APN settings, verifying network mode, resetting network settings, ensuring the software is up to date, and contacting the carrier for potential issues with the recent update. If problems persist, a factory reset might be considered, but it's recommended to contact Samsung support for tailored assistance.
