How to show my number when calling out? 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)
Just put *31# before the number you're calling.
