CallTower Information - Delay In Termination To Cell Phones

Sometimes delay occurs when calling a cell phone.  The reasons for the delay can be: 

-If the called party has a non-voice wireless service active at the moment a call setup is attempted.  (Texting, e-mail),

-If the called party is roaming

-The called phone has not had recent communication with the cellular network,

-If there is a weak radio signal which requires the network to repeat one or more command messages to or from the cell phone being called,
