buy calling card

Projections are now $10 billion per year by 2010 In 1995, US West introduced the
first chip-based prepaid cards in the U.S., while Sprint offered their own version
of calling card, the “FONCARD.” In 2001, the first disposable cell phone calling
card was introduced. All these facts point to some amazing growth!

I have a Treo 700w. I have Verizon as my provider. I have gone through 4 700w’s and awaiting my 5th one. Seems that the software gets corrupted and can not fix. The problem I keep facing is the phone portion. All of a sudden I can not hear the caller and they can not hear me.Also, the Speakerphone is hashed out. I can hear with a headset but the caller can not hear me and when I unplug the headset it cancells the call (hangs up); and the Bluetooth headset does not work (it looks like it is engaged on the software, but once the call comes in the bluetooth phone is hashed out). So basically I lose all phone functions while everything else continues to work (the other software on the PDA is still available). Soft reboot only allows the speakerphone for 1 call, then it is unavailable for the next call, which means I have to do a soft reboot after each time I use the phone and can only use the SPeakerphone once before it hashes out again.Does anyone know of this being an ongoing problem? Does anyone know how I can fix the PDA? Any support is greatly appreciated. I am sure that I must not be the only one having this repeated problem, as I pointed out this will be my 5th pone (or 4th replacement). Oh, a hard reboot does not do anything to help.Post relates to: Treo 700w (Verizon)
