How to show my number when calling out?

Question

I have my SIM card set to block the number I'm calling from when calling out. I need this due to work.



What is annoying is that some contacts I need to get a hold of will usually not pick up "Unknown numbers" that call, requiring me to leave a message. I know if I turn my Call ID back on, they pick up right away. I understand this behaviour, and I do it as well.



My issue is that on my phone, I have to go through 5 menus before my number is unblocked, then back to the main Phone screen, then make the call, then back to those 5 screens to turn the blocking back on.



I know I can block per call, but then I need to remember to turn this on. Is there an easy way I can quickly enable/disable the Call Block setting? I'm on an Asus ZenFone 3 on the Telus network (purchased through 3rd party supplier, not from Telus directly)

Answer

Just put *31# before the number you're calling.



More information: Enabling Caller ID.




Depending on the operator and country, there are a number of prefix
codes that can unblock Caller ID.




  • Australia: 1832 (landline and mobile phones)

  • Czech Republic: 31 (landline)

  • Denmark: 31

  • Germany: *31# (Some mobile providers)

  • India: *31#

  • Ireland: *31# (dialling from mobile) 142 (dialling from landlines)

  • Japan: 186

  • Hong Kong: 1357

  • New Zealand: 0196 (Telecom/Spark)

  • North America: *82 (*UB, UnBlock), 1182 (rotary phone)

  • Switzerland: #31#

  • United Kingdom: 1470



On GSM mobile networks, callers may dial *31# before the number
they wish to call to enable caller ID.
