This is the simpler app to make a hidden call
Note that:
- If does not work you must contact with your phone carrier to request the correct code
- Some phone carriers do not allow this feature
- The code #31# works perfectly for a lot of countries
If you know a code that works and it's not on the list, write us and we will add it
We've polished Hidden Call to make things run more quickly and reliably.
