Warning: This is an advanced user hack, only attempt this if you are confident in your Palm OS skills!
Use at your own risk!!!
Also be sure than you are on an unlimited data plan, like SERO, so that you will not be charged per kilobyte!

Before Sprint launched Power-Vision(EV-DO) all phones could be used as a modem.
After the launch of power-vision it became a little trickier.
Samsung phones can be used as a modem pretty easily.
Originally there was a generic code that I outlined back in March of 2006.
Then Samsung got a little sneakier and changed the generic code to your phone’s unlock code. Luckily that code is fairly easy to get with Sprint.

At any rate Palm takes it one step further-you actually need to add a file to your phone to make it work as a modem.

The easy way is to pay $34 for Pdanet.

The following is for those of you out there who are up doing a little more work to get something for free…

Step 1: Download and install Resco Explorer onto your treo. Here is the application link for a 14 day free trial:
Resco Explorer .prc Linky

Step 2: Download and install the following hack ONTO AN SD/MINI-SD CARD. You can do so either by putting the .prc file directly onto the memory card using a memory card reader, or via Palm Desktop quick install and putting the file into the expansion card file. Hack Linky

Step 3: Launch Explorer on your treo and open up the SD card file for Palm, and then launcher to find the hack file. Highlight the hack file, go to the edit menu and select copy to and then copy it to RAM.

Step 4: Download Sprint Connection Manager. Install the files for the treo.

You should be good to go, if you have any problems connecting you may want to close down hotsync and/or try connecting to the internet from the treo itself before dialing out as a modem.

Do you know how can i get a treo for free from sprint or cheap??


if you add a line i know someone that can get you one for free after 100 dollar rebate. let me know if you are intrested.


Dan, is it true that sprint has “nailed” many customers who unfairly use their phone as a modem by fining them or even terminating their contract?


what about hacking a treo 680? i have thousands of rollover minutes… can i use it as a modem and just use my minutes and not be charged per kb? I have cingular (ATT)


Does any one have a hack for the samsung a920.


With this hack sprint has no way of knowing whether you are using your phone as a modem.

As long as you dont download huge files you’ll be fine.

For the a920 you’ll probably need your phone’s 6 digit MSL unlock code code, although you can try the March 2006 post linked to above.


And how does someone get a MSL unlock code


Any hack’s for a windows Treo?


To do this with a windows treo, just go to your windows folder and open up the “Internet Sharing” program.


Cody- which “internet sharing” program?
The windows folder is quite large- but I don’t see in there.

I seem to be having trouble with this lately. I get an error that says “Unable to Connect. Dial-up networking error #678 has occurred.”

I only started getting this recently. Do you know any solution to this?
