Mobile data isn't working when the SIM card is locked with a PIN. Analyzed the output of adb logcat, it seems that these might be relevant:

Telephony: TelecomAccountRegistry: Failed to get status for, slotId: 0 Exception: java.lang.NullPointerException: Attempt to invoke interface method 'int com.android.internal.telephony.IExtTelephony.getCurrentUiccCardProvisioningStatus(int)' on a null object reference
[...]
Telephony: TelecomAccountRegistry: Failed to get primary stack id

It worked again after removing the SIM pin and restarting the device. The above messages no longer appear.

Some extra observations:

• After enabling and disabling airplane mode, the above errors reappear and a reboot is required.
• After re-installing the PIN, at first boot the SIM card isn't detected and now also voice had no service. A full shutdown and reboot resolved this situation, to restore it to the state in which only data has no service.
• Removing the PIN again and rebooting the device restores data service.
