Can't seem to use mobile data when 2 sim cards are active

[laymank]

Does anyone facing simlar problem like me? When I activated 2 sim cards on my A52 5G, the phone appears to be connected to mobile data, but there is no data flowing in or out at all.

When either one of the sim is deactivated, then only data is flowing.

Same with me.. i need to restart my phone always to get the data back

For me , restarting phone didn't help at all.

set which sim card you plan to serve as your mobile data source

[laymank]

Yes, done exactly that. All data flow just stopped working once both sims are active.

hv u tried to switch the sim location at the sim tray?

[laymank]

I didn't. But the data for individual sim works just fine when only one sim is active.

I don't see a need to swap the sim location.

u could also try to reset the network settings to see if the issue still persists

Did that, too after Google g around for solution. Didn't help.

In the end, I submitted error reports to Samsung support. After a few round of troubleshooting, they told me to reset my phone to factory setting. And if that stoll didn't work, to visit Samsung service centre.
