I want to ask how can we block some number permanently in windows Lumia phone 525 such that its not even visible in blocked messages and calls.I even don't want caller calls and messages in blocked.
Call Forwarding (you have to order the service from the operator)
002# - Cancel all diverts
004# - Cancel all conditional call forwarding
**004* phone number # - Activate all conditional call forwarding
Unconditional call forwarding (Call Forward All)
21 - Switch off and deactivate
21# - Deactivate
**21*phone number# - Enable and Activate *21# - Activate *#21# - Check the condition
Diversion in case of "no answer"
61 - Switch off and deactivate
61# - Deactivate
**61* phone number# - Enable and Activate *61# - Activate *#61# - Check the condition
Setting the call time until the call forwarding option "no answer" When installing forwarding on "no answer" you can set the time in seconds that the system allows you to hook. If during this time you have not picked up the phone, the incoming call will be diverted. Example: - ** 61 * + ** 709576617601234 # 30 - set the waiting time of 30 seconds Set timeout - ** 61 * Phone Number ** N #, N = 5..30 (seconds) Remove the previous installation - ## 61 #
