In order to mask your cell phone number when using the call-back feature in the Page Message, you must do the following:
- Open SmartPager app on your device
- Click Settings
- Turn ON the "Block My Number"
*** Ensure Block Caller ID feature is turned Off in your phone's settings: otherwise this conflicts with the SmartPager's Caller ID Blocking.
Now, when you return a call your phone will display either your pager number or your office's main number, depending on how your account was configured.
