- [11/04/99] - Programming a QUALCOMM Cell Phone
-
- I should have written this article a while ago, but I have been
- postponing it due to the fact that I'm not sure how useful it will be.
- While I was goofing around with my cell phone I realized how easy it was
- to get into the "non-customer" features. By typing in the number "1" six
- times (it should look like 111-111) and pressing in the dial shuttle you
- can bring up a new menu. This menu contains three extra functions,
- Version, Programming and Field Debug. Obviously if you select Version it
- will show your phone's version, mine reads: DB2.0.10. Version also gives
- you a submenu named "more" which reads PRL then a four digit #. I'm not
- sure what this stands for but it could be the personal ID number for
- whoever set up your phone. Now to the more interesting stuff. The Field
- Debug menu requires you to enter a six digit code before you can access
- it. On my phone (the QCP-1920, ver.2.0.10) the access code is really
- simple, "000000" After you press the last zero the menu reads "Screen,
- Test Calls, Errors, Clr Errors, and 13k Voice. If you have a dual mode
- phone your passwd might be different. I'm not going to explain all of
- the features because I don't want to bore you, but the one I find most
- interesting is the Test Calls. Once you are in the Test Calls menu u can
- do many different things. You can make a call in 8k or 13k while testing
- for errors, but it will only let you test for about 34sec per call.
- There is also a loop test which can be performed in 8k or 13k. The 8k
- did not work for me even when I disabled 13k voice. but the 13k did just
- fine. Speaking of disabling 13k voice this can be done by selecting 13k
- Voice in the main debug menu. I made a few calls with it 13k voice
- enabled and disabled but I noticed no difference.
-
- I know you probably only wanted to know about the Programming option
- so I'll move on. When you select Programming, like the Debug Menu,
- stops you with a required passwd input. This passwd is differs from each
- calling area. So in theory every one in the Seattle area should have the
- same programming code. The code has to be six digits long and no,
- "000000" does not work. Now you either can type in 000000 through 999999
- until you get the right code, (not only would that take a REALLY long
- time but just to help slow you down, your phone will shut off every
- incorrect passwd entered) or you can do a little social engineering.
- They best way to get the code it to call your cell phone service
- provider and tell them you need to change your number. Give any reason u
- like, like you want to change your # cuz you have been receiving
- harassing phone calls. Now you also need to have a excuse for why you
- can't come in to their service center just incase. Now if all goes well
- they should have you re-program your # right there while your talking to
- them. Which means they'll have to give you your phone's passwd. Now try
- to remember everything he/she has you do for later reference, its not to
- hard to do but if your worried you can always record the conversation.
- One thing to keep in mind, they might change the code right after you
- get off the phone. So make sure you enter the Programming menu ASAP.
- Most likely they wont change it for a few months or not at all if your
- real lucky. Well I hope this helps you get started on "customizing" your
- QUALCOMM phone. In the future I'll try to write another article that
- goes into more of the programming codes, so keep checking back every
- once and a while.
