How do you suppress the phone number on huawei p20 lite?

There are two options for number suppression in the GSM network:

1.) Suppress phone number for all outgoing calls:

To do this, enter the code * 31 # on the keyboard of your smartphone and confirm with the dial button (green receiver). From now on, your number will NOT be displayed for all outgoing calls. This setting is deactivated again by entering the code # 31 # and confirming with the dial button (green receiver).

2.) Withhold number only once:

To do this, enter the code # 31 # - followed by the desired phone number - and confirm with the dial button (green receiver), e.g. # 31 # 01761234567. Your phone number is only suppressed for this one call.
