Samsung A12 keeps disconnecting from cellular network data

Dear support,

Recently I got myself a new Samsung A12 (SM-A125F/DSN). I do like the phone however it has a very annoying issue/bug while roaming. Can you please help me solving this problem? Thanks!

The problem

The data connection keeps disconnecting frequently which makes it impossible to make whatsapp calls or stream youtube/spotify etc. without interruptions. The same happens while just browsing the web in Chrome.

The signal bars with the R (roaming) on top always have 4 bars. The icon next to it with either 3G/4G/H transmitting data disappears at the moments I lose connection.

As written I am roaming, In my home country (Netherlands) the phone does not have this problem! Right now I am in Poland and no matter where I am in the country, the problem is constantly there. This problem does not occur using the same simcard in my old Samsung J3 2017 (Android 9).

What I tried

- Rebooted the phone

- Reset to factory defaults

- Reset data connection settings

- Swapped the simcard from 1 to 2

- Updated all apps and running the latest firmware

have you made sure that data is allowed when roaming in the connection settings?

Absolutely! In the settings Connections > Mobile networks > Data roaming is switched on.

Very unfortunate to see Samsung isn't replying to this. Figured out the problem isn't just data related. If I do phonecalls they get disconnected as well😞 Feels like quantity over quality is more important nowadays.
