I just receives new official firmware update Android 11 UI 3.0. Update went very well, but after update the network data is not working. Wifi works, I can make phone calls, but no network data. I have already rwstartes phone several time and even made hard reset, but no help:(
Is anyone experiencing same issue after Android 11 update??

When you say Hard Reset did you mean a Factory reset after backing up @Libroid  ?

Have you checked that mobile data is enabled for SIM 1 in the SIM card manager.

 

Settings > Connections > SIM card manager > Mobile data (SIM card 1)

Same here. Tried a factory reset and reinstall with no luck but using sim 2 tray or downselecting the network and then walking back up to 4G (as described at the links) works fine). Frustrating but hopefully a patch is on its way.

Got the same issue after the update in UK... slot 1 no mobile data... slot 2 works perfect... strange is that if I let data on and move around the city at some point I get internet.. 4g and 5g... as soon as I switch it off it won't go back on again so is definitely a software problem here. Samsung?
Also got the advice written above... put sim in slot 1, activate you data, on settings, mobile networks, network mode... select 3g/2g first and you get H/H+ after select the one above LTE/3g/2g and after the option 5G/LTE/3G/2G AND YOU GET 4G+... Now don't know how much will last or if you need to do this all the time... hope Samsung working ok it because is no reason to send the phone for repair...
