Hello,

Soft Reset
A Soft Reset stops all active (or open) programs and "reboots" the handheld. When the Treo powers back up, you'll start with all programs closed and the unit will be ready to use. The soft reset is intended to reset the Treo if it is malfunctioning or has become bogged down.
The Palm Treo 750 can be soft reset by quickly pressing and releasing the tiny red button beneath the miniSD memory card door:
Hard Reset
A Hard Reset wipes the internal memory and returns the Treo to its factory specs, in effect returning the Treo 750 to the state it was in when you purchased it. All data entered, preferences set or software installed on the Treo after purchase will be lost after a hard reset and will have to transferred or reinstalled via ActiveSync / Windows Mobile Device Center.
The Palm Treo 750 can be hard reset by pressing and holding the power button (seen left) while at the same time pressing and holding reset button beneath the miniSD memory card door. Press and hold the two buttons until the screen completely fades. When the screen returns, you'll be given the option to "Erase all data." Select Yes to complete the hard reset. The Treo will now be as it was when it left the factory and you can start fresh. You may have to perform a soft reset after the hard reset to get the unit to power on.

my favourite (treo 750) i own 1 but not sure i have had that problem yet depending on if you install a program it could be causing that problem maybe a call blocker! u could check to see if ur network is on automatic
start-setting-personal-phone-network-netselection automatic
try backing up your phone data then master reset back to factory setting
N.B you would loose everything that cannot be backed up but this solved my bluetooth problem 1 time holding down the reset button then press power. when prompted to reset say yes

have you tried to hard reset the unit - backup your personal data before you do

set different ring to different callers.

mayb you can try to do a hard reset.
Take out your battery press and hold end call button ( don't release ) then put in your batery wait the loading finished and change to other screen then you release your from the end call button you pressing just now.If still can't work,no choice need to go back to you service center .

i have palm treo 680 mobile phone
i have use any sim my phone

There is a treo repair website that shows you how to replace the screen yourself.

Sad to say - you need to go get out your phone bill and call Sprint - they may need to fix their end of the internet connection. They often disconnect services you have paid for and can't use. In any case their tech support is pretty good. They can also reset your password and let you know your text message address.

Do you have a Treo desktop charger/sync cradle where you can drop the battery into the charger?
