After installing CyanogenMod 13 on Xiaomi Redmi Note Pro 3, the smartphone does not see contacts on the Sim Card.
If you have not deleted the contacts from the Sim Card, they are still located on it, and there are several ways to reach them:
Open the Dialer, go to Settings, and then select “Import/Export” – “Export to VCF file”. Transfer this file to your smartphone and import the contacts on your smartphone using the same settings.
Is the problem solved?
