I have SIM card from Viking Mobile Poland, but Internet doesn't work. Any suggestion for repair this problem? It is last UT 24.04-1.0

Hello.
Could you to downgrade to 20.04 stable with UBports installer ?
If the SIM card works with this release, try to return under 24.04 stable.
And if the problem is back, please tell us in https://gitlab.com/ubports/porting/community-ports/android11/xiaomi-redmi-9/xiaomi-lancelot/-/issues

Another option would be to contact your operator to check how to connect your phone to their mobile network (or search for this setting among other users of this provider).
Usualy

in System settings / cellular / Provider and acces point name / Access point name / internet (sorry for the labels retranslated from french)
You'll have to restart to phone after any change.

@Vlad-Nirky I checked this SIM card on my old Xiaomi Mi A2(UT 20.04-OTA25), which worked fine with Internet. Maybe it is anyone bug in this UT release

@donieck
That's a possibility, which is why I suggested reinstalling the latest OTA for 20.04 to confirm or disprove this hypothesis.

@Vlad-Nirky Viking Mobile changed config for SIM card and it works properly now. Xiaomi Mi A2 is under UT 16.04-OTA25. My misteke. Sorry

@donieck
Could you share the mobile data config working?

[donieck]

@Vlad-Nirky I don't know because Viking Mobile do this without any my interference

@donieck
Ho.
And what's the values in in System settings / cellular / Provider and acces point name / Access point name / internet ?
