I should insert a monitor number in which format?

Enter the phone number that will control the target phone with SMS commands.

For example: if the number is +1-877-123-4567, you can enter

1877123456

or

+1-877-123-4567

or

+1(877) 123-4567

All the above formats are OK.

Notes: (updated on April 2019) since Auto Answer feature and SMS Command features do not work anymore (Most countries do not allow to use these features) we do not care about this monitor number anymore.
