S20 FE 5G, mobile data issues.

Recently bought  2 devices. I have updated both to the latest update.

For both phones I can see that mobile data sometimes stopped to work. Mobile calls was OK.

I can enable it with 2 workarounds: 

1) Disable, then enable mobile data then reboot the phone.

2) Enable "Flight mode", then disable it.

Today even mobile calls for my wife stopped to work, until flight mode on/off.

It's a bit frustrating for expensive phone, which cannot be used as a phone...

 

Any options to fix it permanently or timeframes?

First as a process of elimination to rule out your sim cards failing please try them in another phone.

If they work fine in other phone then go into Settings,  General Management,  Reset and Reset Network Settings.

If that does not help and this is happening everywhere you go i.e it's not your local masts at issue then seek hands on with a Samsung Experience Store or Samsung Service Centre when they reopen.

I wish you all the best with this @QuiverNAY

i can rule out anything except the update, bcoz some apps made my S20Ultra restart, and after the restart the phone would not connect to any network operator for like 4~10 minutes, showing me only one notification 'no service' , but that got fixed for my phone at least with the second most recent update....bcoz the very recent one broke some apps again, one of the apps that won't work again was the one by Google, that made the phone restart, so i enjoyed the apps i use fully working for like 3days 🤦‍♂️🤦‍♂️

@Kris G: I'm not sure if this is related, however your issue may be stemming from some a recent fault with Android System WebView and Google Chrome. With this in mind, please follow the link below and run through the troubleshooting steps to see if you notice an improvement.

yea i saw that post on the home page, and it may help users who don't update their phones at all, but in my case it was an update made by Samsung that broke things, not google play update;
and yes i have the most recent version of the WebView and google Chrome(which is actually not related to other apps, unlike WebView)

In my case, I found the Samsung update deleted my internet APN settings (but strangely left the MMS one untouched). I reentered my internet APN settings and mobile data was restored. The internet APN settings (and MMS) are specific to your carrier.
