1. Disguise your caller ID
Try hiding your caller ID. It is usually important and it helps in masking your identity when calling a person who blocked you. The recipient won’t be able to know who is calling them and this may prompt her or him to answer your call.
If you need to disguise your caller ID on iPhone, go to your settings and click the “Phone” section of the settings. Select “Show My Caller ID” and then turn it off.
For android devices, on settings, select call, then click additional. Once you are there, select Caller ID, under it click Hide Number. Your calls will remain hidden.
2. Dial *67
This code will simply mask your number and appear as “unknown” or private number to the recipient. Before entering the number you wish to call, first dial *67 followed with the number. For instance, *670708111111.
3. Download an app that generates a random phone number.
There are various free apps that you can download from the Google Play Store. This app will generate a random number that you can use to call somebody who is not even using the app. With these apps, the receiver won’t be able to trace the person calling them.
4. Change your number
This can be the best option. Buy another line and give her or him a call.
