If the phone signal is weak, she's not going to have much luck with calls. Maybe she needs a different network - the Precedent runs on Sprint. (And if she's using wifi to access the internet, that can cause what you describe with a weak phone signal.)

 

We have had enough with the sprint service. we are re activating the Nokia E71 that we had before this POS service. My wife`s phone now has multiple bars signal strength and no dropped calls!!!!
