Disposable anti-AON - is there such an app for iPhone?

Question

Android

Sometimes you need to make a call with a hidden number (otherwise the recipient of the call will enter my number into the database and will regularly call and take out the brain when it is not necessary at all). I have to go into the settings, turn off the definition, call, and then, after a week, find out that I forgot to remove the setting back and I call all my colleagues and acquaintances with an undefined number, which makes them start to tense up or think, why am I hiding from them. Is there an app that allows you to make ONE call with a disabled caller ID, and then return the setting to its normal state?
There is a prefix 141 dialed in front of the number in order to enable caller ID blocking for this call only, except that my operator said that they do not support this feature.

Answer 1

Try *67 as a prefix before the subscriber's number.

Answer 2

And why, if everything can be made easier. There is a special GSM code for this (network standard service that works in almost any network).
We dial *31# and the number of the subscriber whom we want to call with anti-AON enabled, then press the key / icon (depending on the phone) of the call

Answer 3

"download brain.apk, memory enhancer.ipa, free without SMS, SHOCK VIDEO "

Answer 4

Is Skype not suitable?
