Some of these codes work only on CDMA models, but most of them are for both versions of Treo. For SPRINT CDMA models you should enter "# # ..." before number the code, and for GSM models you have to enter "# *...", and for VERIZON CDMA, enter "# * # ...", where "..." is the number code. Enter the codes as if you are actually dialing the number from your Phone app.
Signal strength is given as "RSSI," which stands for "Received Signal Strength Indicator."
Please note: the function of many of these codes remains a mystery to enthusiasts. A lot of them were discovered through trial and error (yes, we have a lot of time on our hands) -- while the presence of some of these codes can be easily discovered this way, their purposes are often more difficult to understand. We have indicated some codes with which users should be particularly careful.
Very useful codes:
